  1. A.Traction
  2. B.Saltation
  3. C.Suspension
  4. D.Solution
Show answer & marking scheme

Worked solution

Suspension is the process by which very fine and light material is carried along within the flow of the water. Traction rolls large rocks, saltation bounces medium particles, and solution carries dissolved minerals.

Marking scheme

Award 1 mark for the correct answer (C).
Question 4 · MCQ
1 marks
Which Milankovitch cycle describes the variation in the shape of the Earth's orbit around the Sun, changing from nearly circular to mildly elliptical over a 100,000-year cycle?
  1. A.Precession
  2. B.Obliquity
  3. C.Eccentricity
  4. D.Solar output
Show answer & marking scheme

Worked solution

Eccentricity refers to the changes in the shape of the orbit of the Earth around the Sun, transitioning between circular and elliptical cycles every 100,000 years. Obliquity is axial tilt, and precession is the axial wobble.

Marking scheme

Award 1 mark for identifying Eccentricity (C).
Question 5 · MCQ
1 marks

  1. A.Forest floor
  2. B.Understorey
  3. C.Canopy
  4. D.Emergent layer
Show answer & marking scheme

Worked solution

The emergent layer contains the tallest trees in the rainforest that poke out above the canopy, coping with direct intense sunlight, high winds, and lower humidity.

Marking scheme

Award 1 mark for the correct answer (D).
Question 6 · short_answer
2 marks
Explain one way in which past tectonic processes have influenced the physical landscape of the UK.
Show answer & marking scheme

Worked solution

Past tectonic processes, including volcanic eruptions and folding, created resistant igneous and metamorphic rocks (such as granite and slate) in the north and west of the UK. Over millions of years of erosion, these harder rocks resisted weathering and erosion far better than the softer sedimentary rocks of the south and east, resulting in upland mountainous landscapes like the Lake District or the Scottish Highlands.

Marking scheme

Award 1 mark for identifying a relevant tectonic process or rock type (1), and a further 1 mark for explaining how this influenced the landscape/topography (1). For example: Volcanic eruptions formed resistant granite (1), which resisted erosion to form upland tor landscapes (1).
Question 7 · short_answer
3 marks
Explain how a discordant coastline develops over time.
Show answer & marking scheme

Worked solution

Discordant coastlines occur where bands of different rock types run perpendicular (at right angles) to the coast. Differential erosion occurs because softer rocks (such as sands and clays) are eroded rapidly by hydraulic action and abrasion to form bays. Conversely, harder, more resistant rocks (such as chalk or limestone) erode much more slowly, leaving them jutting out into the sea as headlands.

Marking scheme

Award 1 mark for identifying the geology layout (alternating bands of hard and soft rock perpendicular to the coast) (1). Award 1 mark for explaining differential erosion (soft rock eroding faster than hard rock due to wave action) (1). Award 1 mark for linking this to the formation of headlands and bays (1).
Question 8 · short_answer
2 marks
Explain the process of rotational slumping on a coastline.
Show answer & marking scheme

Worked solution

Rotational slumping is a form of mass movement. It begins when heavy rain saturates clay or unconsolidated sediment, increasing its weight and reducing friction along a slip plane. Gravity then pulls the unstable mass of cliff down, causing it to slide or slip backwards along a concave (curved) slip plane towards the beach, leaving a curved scar on the cliff face.

Marking scheme

Award 1 mark for explaining the role of water/saturation (saturates the cliff, adding weight or lubricating the slip plane) (1). Award 1 mark for explaining the movement (the rock/soil slips or rotates downwards under gravity along a curved slip plane) (1).
Question 9 · short_answer
3 marks
Explain how an oxbow lake is formed.
Show answer & marking scheme

Worked solution

An oxbow lake starts as a highly pronounced meander loop. Lateral erosion (hydraulic action and abrasion) occurs on the outer bends, while deposition occurs on the inner bends, narrowing the neck of the meander. During a flood or high-flow event, the river takes the straightest, shortest route and cuts through the narrow neck. The river flow then bypasses the old bend. Deposition eventually seals off the ends of the old bend, leaving an abandoned, crescent-shaped body of water called an oxbow lake.

Marking scheme

Award 1 mark for explaining the narrowing of the meander neck due to erosion on the outer bends (1). Award 1 mark for describing the river cutting through the neck during high flow/flood (1). Award 1 mark for explaining that deposition seals off the old bend to isolate the lake (1).
Question 10 · short_answer
2 marks
State two physical factors that can decrease the lag time on a storm hydrograph.
Show answer & marking scheme

Worked solution

Physical factors that shorten the lag time (the time between peak rainfall and peak discharge) include: (1) Impermeable rock or clay soils, which prevent water infiltrating, leading to rapid surface runoff. (2) Steep valley slopes, which cause gravity to pull water down to the river channel very quickly. (3) Saturation of the soil from previous rainfall, preventing further infiltration.

Marking scheme

Award 1 mark for each valid physical factor identified, up to a maximum of 2 marks. Acceptable answers include: steep slopes/gradient (1); impermeable rocks/geology (1); saturated soils/antecedent rainfall (1); high drainage density (1); intense precipitation (1). Do not accept human factors like urbanisation or deforestation.
Question 11 · short_answer
3 marks
Explain how Milankovitch cycles cause long-term climate change.
Show answer & marking scheme

Worked solution

Milankovitch cycles refer to three natural variations in the Earth's orbit over thousands of years. First, eccentricity changes the Earth's orbit from circular to elliptical, altering how close the Earth gets to the sun. Second, obliquity changes the tilt of the Earth's axis, affecting the intensity of the seasons. Third, precession is the wobble of the Earth's axis. Together, these cycles change the amount and distribution of solar energy received by the Earth, leading to long-term shifts between glacial (cold) and interglacial (warm) periods.

Marking scheme

Award 1 mark for identifying at least one specific cycle (eccentricity, obliquity, or precession) (1). Award 1 mark for explaining how this cycle changes the Earth's orbit or axis tilt (e.g., eccentricity changes the orbit shape from circular to elliptical) (1). Award 1 mark for linking these orbital changes to variations in solar radiation received, causing glacial/interglacial cycles (1).
Question 12 · short_answer
2 marks
Explain why low-pressure belts, such as the equator, experience high levels of precipitation.
Show answer & marking scheme

Worked solution

At the equator, the sun's rays are highly concentrated, causing intense heating of the Earth's surface. This warms the air above it, making it less dense so that it rises, creating an area of low pressure. As this warm, moist air rises, it cools and water vapour condenses to form cumulus clouds, resulting in high levels of precipitation.

Marking scheme

Award 1 mark for explaining that warm air rises due to intense solar heating at the equator (1). Award 1 mark for explaining that as the air rises, it cools and condenses to form clouds and rain (1).
Question 13 · short_answer
3 marks
Explain how nutrients are cycled within a tropical rainforest ecosystem.
Show answer & marking scheme

Worked solution

The nutrient cycle in a tropical rainforest is exceptionally rapid due to the hot, wet climate. First, large amounts of organic matter (like dead leaves and branches) fall to the forest floor, forming a thick litter layer. Second, the warm, moist conditions allow decomposers (fungi and bacteria) to break down this litter extremely quickly, releasing nutrients into the soil. Third, shallow-rooted rainforest trees immediately absorb these nutrients to support their rapid growth, meaning very few nutrients remain in the soil for long.

Marking scheme

Award 1 mark for identifying the input of nutrients via falling litter/organic matter (1). Award 1 mark for explaining rapid decomposition of litter due to hot, wet conditions (1). Award 1 mark for explaining that trees rapidly absorb these nutrients from the soil, leaving the soil relatively nutrient-poor (1).
Question 14 · Short Structured
2 marks
Explain one difference between constructive waves and destructive waves.
Show answer & marking scheme

Worked solution

Constructive waves have a stronger swash than backwash, which deposits material on the beach (1 mark), whereas destructive waves have a stronger backwash than swash, which erodes and removes material from the beach (1 mark).

Marking scheme

Award 1 mark for identifying a difference in wave action (e.g. swash vs backwash strength) and 1 mark for explaining the impact of this difference on the beach (deposition vs erosion).
Question 15 · Short Structured
3 marks
Explain how river discharge changes downstream.
Show answer & marking scheme

Worked solution

River discharge increases downstream (1 mark) because more tributaries join the main river channel as it moves towards the mouth (1 mark), and the catchment area increases, meaning more surface runoff contributes to the total volume of water (1 mark).

Marking scheme

Award 1 mark for identifying the trend (discharge increases) and up to 2 further marks for explaining why (tributaries joining, increased catchment area, or reduced friction/increased velocity).
Question 16 · Short Structured
2 marks
Explain one way in which human activity has increased the concentration of methane in the atmosphere.
Show answer & marking scheme

Worked solution

An increase in commercial livestock farming (such as cattle) (1 mark) has led to more methane being released into the atmosphere as a byproduct of the animals' digestive processes (1 mark). Alternatively, increased rice paddy cultivation (1 mark) leads to anaerobic decomposition of organic matter in flooded fields, releasing methane (1 mark).

Marking scheme

Award 1 mark for identifying a relevant human activity (e.g., intensive livestock farming, landfill sites, rice cultivation) and 1 mark for explaining how it releases methane.
Question 17 · Short Structured
3 marks
Explain the role of decomposers in the nutrient cycle of a tropical rainforest.
Show answer & marking scheme

Worked solution

Decomposers such as fungi and bacteria break down dead organic matter (leaf litter) on the forest floor (1 mark). This chemical breakdown releases essential nutrients back into the topsoil (1 mark), which are then rapidly absorbed by the shallow root systems of tropical trees to support new growth (1 mark).

Marking scheme

Award 1 mark for identifying the action of decomposers (breaking down dead organic matter/litter). Award 1 mark for explaining the release of nutrients into the soil. Award 1 mark for linking this to the rapid uptake of nutrients by vegetation.
Question 18 · Short Structured
2 marks
Explain how the geology of the UK affects the distribution of its upland landscapes.
Show answer & marking scheme

Worked solution

Upland areas are predominantly located in the north and west of the UK because these regions are formed of hard, resistant igneous and metamorphic rocks (such as granite or slate) (1 mark). These rocks are highly resistant to weathering and erosion, leaving them as high-relief mountains and hills over time (1 mark).

Marking scheme

Award 1 mark for identifying the link between upland areas and resistant rock types (igneous/metamorphic) or their location (north/west). Award 1 mark for explaining that these rocks resist erosion/weathering, maintaining high relief.
Question 19 · Short Structured
3 marks
Explain how orbital changes (Milankovitch cycles) can cause global temperatures to change.
Show answer & marking scheme

Worked solution

Milankovitch cycles consist of three main orbital variations: eccentricity (changes in the shape of Earth's orbit), obliquity (changes in Earth's tilt), and precession (wobble of Earth's axis) (1 mark). These cycles alter the distance of the Earth from the Sun and the angle at which solar energy hits the surface (1 mark). This changes the total amount of solar radiation (insolation) received by the Earth, which can trigger natural shifts between ice ages (glacial periods) and warmer interglacial periods (1 mark).

Marking scheme

Award 1 mark for identifying a specific orbital change (eccentricity, obliquity, precession). Award 1 mark for explaining how this affects solar radiation/insolation received by the Earth. Award 1 mark for linking this to global temperature changes (glacials/interglacials).
Question 20 · essay
8 marks
Assess the effectiveness of global scale initiatives compared to local scale initiatives in protecting tropical rainforest ecosystems.
Show answer & marking scheme

Worked solution

Global scale initiatives like CITES (Convention on International Trade in Endangered Species) and REDD+ (Reducing Emissions from Deforestation and Forest Degradation) are critical because they address the systemic drivers of deforestation, such as international timber trade and carbon emissions. CITES effectively blocks the illegal market for endangered hardwood species, while REDD+ offers financial incentives for developing countries to keep forests standing. However, global schemes can suffer from weak enforcement, lack of international compliance, and bureaucratic delays. Local scale initiatives, such as community-managed ecotourism (e.g., in Costa Rica) and selective logging schemes, directly engage indigenous populations and offer immediate economic alternatives to destructive practices like cattle ranching or clear-felling. The main limitation of local schemes is that they are often small-scale and cannot easily halt major national infrastructure projects or widespread illegal logging without strong governmental backing. Ultimately, while local initiatives ensure community buy-in and direct conservation, they rely on global frameworks to curb international market demands and provide the overarching funding needed to make conservation economically viable.

Marking scheme

AO2 (4 marks): Demonstrates knowledge and understanding of global initiatives (e.g. CITES, REDD+, debt-for-nature swaps) and local initiatives (e.g. selective logging, ecotourism, sustainable farming) in tropical rainforests.
AO3 (4 marks): Evaluates and assesses the relative effectiveness of both scales of management, identifying limitations and strengths, leading to a justified conclusion.

Level 1 (1-3 marks): Demonstrates isolated elements of understanding of rainforest management. Analysis is basic, focusing on simple descriptions of one or two strategies with little comparison of their effectiveness.
Level 2 (4-6 marks): Demonstrates good geographical understanding of both global and local strategies. Explains how they protect ecosystems. The assessment is developed, comparing the scales of management, though it may favor one side or lack a fully balanced conclusion.
Level 3 (7-8 marks): Demonstrates precise and comprehensive geographical understanding of both scales of initiatives. Evaluates both sides with balanced, logical reasoning. Offers a clear, justified judgment on their relative effectiveness, supported by evidence.
Question 21 · essay
8 marks
Assess the significance of Milankovitch cycles (orbital changes) compared to solar output variations in causing past climate change during the Quaternary period.
Show answer & marking scheme

Worked solution

Milankovitch cycles operate on very long, predictable timescales: eccentricity changes the Earth's orbit from circular to elliptical over a 100,000-year cycle, axial tilt (obliquity) varies between 22.1 and 24.5 degrees over 41,000 years, and precession (wobble) occurs on a 23,000-year cycle. Together, these orbital changes alter the distribution and intensity of solar radiation reaching the Earth's surface, triggering the major glacial and interglacial periods of the Quaternary. In contrast, variations in solar output operate on much shorter cycles, most notably the 11-year sunspot cycle, as well as longer solar minimums (like the Maunder Minimum, which contributed to the Little Ice Age). While solar output variations can cause minor, short-term regional cooling or warming trends, they do not possess the magnitude or sustained temporal scale required to plunge the planet into or out of full-scale ice ages. Therefore, Milankovitch cycles are of paramount significance for long-term Quaternary climate shifts, while solar output variations act as secondary, shorter-term modifiers of the global climate system.

Marking scheme

AO2 (4 marks): Demonstrates knowledge and understanding of how orbital changes (eccentricity, obliquity, precession) and solar output variations influence the global climate system during the Quaternary.
AO3 (4 marks): Evaluates the relative significance of these mechanisms, analyzing their respective timescales (tens of thousands of years vs. decades/centuries) and climate impacts (glacial cycles vs. minor temperature anomalies).

Level 1 (1-3 marks): Shows basic knowledge of orbital changes or sunspots. Description of climate change causes is descriptive with little comparative evaluation of their significance.
Level 2 (4-6 marks): Shows clear geographical understanding of both Milankovitch cycles and solar output. Explains how they affect climate. The assessment begins to compare their relative significance, though it may lack depth regarding specific cycles or timescales.
Level 3 (7-8 marks): Demonstrates comprehensive geographical understanding of both mechanisms. Conducts a highly structured, balanced evaluation of their significance over the Quaternary period, concluding with a logical, well-supported judgment on why orbital changes are the primary driver of major glacial shifts.
Question 22 · essay
8 marks
For a named UK river basin, assess the extent to which human activities have increased the risk of flooding.
Show answer & marking scheme

Worked solution

In the River Severn basin, human activities have significantly amplified flood risks, though they act alongside natural physical factors. Urbanization in towns like Shrewsbury, Worcester, and Gloucester has led to the construction of impermeable surfaces (concrete, tarmac) and extensive drainage networks. This reduces infiltration, accelerates surface runoff, and shortens the lag time on the river hydrograph, leading to rapid, high peak discharges. Deforestation in the upper catchment of the Welsh hills for pastureland has further reduced interception and evapotranspiration, meaning more water enters the river systems rapidly. Additionally, intensive agriculture has caused soil compaction, lowering the soil's infiltration capacity. However, these human actions must be balanced against extreme physical factors. The River Severn basin is subject to heavy, prolonged relief rainfall from Atlantic depressions, and the upper catchment has steep slopes with impermeable clay and crystalline geology. While natural factors set the baseline vulnerability of the catchment, human activities have dramatically worsened the frequency and severity of peak flood events, making human actions a highly significant contributor to modern flood risk.

Marking scheme

AO2 (4 marks): Applies knowledge and understanding of how human activities (urbanization, land use change, river management) and physical factors (geology, relief, weather) influence river processes and flood risk in a named UK basin.
AO3 (4 marks): Evaluates and assesses the extent to which human factors are responsible for flooding compared to natural factors, leading to a reasoned and supported judgment.

Level 1 (1-3 marks): Outlines basic human causes of flooding (e.g., building roads, cutting down trees). Reference to a specific basin is weak or absent. Minimal evaluation of human vs. physical factors.
Level 2 (4-6 marks): Explains specific human activities and physical factors within a named UK river basin. The assessment of which factor is more significant is developed, showing clear connections between land use and the hydrological cycle.
Level 3 (7-8 marks): Detailed, case-study-specific assessment of the named UK river basin. Demonstrates a sophisticated understanding of how human actions interact with physical catchment characteristics to exacerbate flood risk, culminating in a highly balanced, well-justified conclusion.
Question 23 · essay
8 marks
Assess the extent to which the choice of coastal management strategies on a named UK coastline is influenced by conflicting economic and environmental interests.
Show answer & marking scheme

Worked solution

Along the Holderness Coast in Yorkshire, the choice of management strategies is heavily contested due to economic and environmental conflicts. At Mappleton, the decision to install two rock groynes and a rip-rap barrier in 1991 was economically motivated to protect the B1242 coastal road and local homes, costing over £2 million. This successfully halted erosion locally. However, this decision created severe environmental and economic conflict further south. The groynes trapped sediment, starving beaches downdrift (such as at Great Cowden) of material. Lacking beach protection, cliffs at Great Cowden experienced accelerated erosion, leading to the loss of valuable agricultural land and caravan parks. Similarly, protecting the gas terminal at Easington with rock armour is a national economic priority, but it prevents the natural erosion of cliffs that feeds sediment southwards to Spurn Point, a vital geological spit and nature reserve. Consequently, coastal management cannot satisfy all stakeholders; high-value economic assets are heavily protected, while agricultural and environmentally sensitive areas are often sacrificed through 'managed realignment' or 'no active intervention' due to cost-benefit analyses, showing that economic concerns often override local environmental impacts.

Marking scheme

AO2 (4 marks): Demonstrates knowledge and understanding of different coastal management strategies and their physical/human impacts along a named UK coastline.
AO3 (4 marks): Evaluates the extent to which conflicts between economic interests (e.g., infrastructure, tourism, homes) and environmental factors (e.g., sediment starvation, habitat protection, coastal processes) determine which strategies are chosen.

Level 1 (1-3 marks): Identifies some basic coastal defences (e.g., sea walls, groynes) with limited or generic reference to a UK coastline. Basic mention of cost or environmental damage.
Level 2 (4-6 marks): Explains coastal management decisions at specific locations along a named UK coastline. Clearly identifies conflicts between economic assets and environmental impacts. The assessment of how these conflicts influence decisions is developed.
Level 3 (7-8 marks): Provides a highly detailed and balanced assessment of a named UK coastline. Synthesizes complex geographical relationships, explaining how cost-benefit analyses, sediment cells, and stakeholder conflicts dictate management plans (such as Shoreline Management Plans), culminating in a clear, well-supported conclusion.

Question 1 · MCQ
1 marks
Identify one pull factor that encourages suburbanisation in UK cities.
  1. A.The expansion of heavy manufacturing industry in the central business district (CBD).
  2. B.Greater availability of larger houses with gardens and more green open space.
  3. C.High levels of atmospheric pollution and traffic noise in the inner-city areas.
  4. D.Deindustrialisation and the loss of manufacturing jobs in the urban core.
Show answer & marking scheme

Worked solution

Suburbanisation is the outward movement of people from the inner city to the suburbs. A pull factor is a positive aspect that attracts people to a new area. Greater availability of larger houses with gardens and open green spaces (Option B) is a classic pull factor. Options C and D are push factors (negative aspects driving people away from the inner city), and Option A is incorrect because manufacturing did not expand in the CBD during suburbanisation.

Marking scheme

Award 1 mark for the correct option (B).

  3. C.The areas of highest population density are in the south-east, while the areas of highest rainfall are in the north and west.
  4. D.The areas of lowest population density are in the south-east, while the areas of highest rainfall are in the north and west.
Show answer & marking scheme

Worked solution

The UK's water mismatch is spatial: the areas of highest rainfall (supply) are in the mountainous north and west, whereas the highest population density and economic activity (demand) are located in the flatter, drier south-east.

Marking scheme

Award 1 mark for the correct option (C).
Question 4 · MCQ
1 marks
Which of the following is a major environmental challenge caused by the rapid, unplanned growth of informal settlements in emerging country megacities?
  1. A.A complete decline in the informal sector, leading to high unemployment rates.
  2. B.Rapid depopulation of the urban core as residents migrate back to rural farming areas.
  3. C.Decreased air pollution levels due to the lack of vehicle ownership among informal settlement residents.
  4. D.Severe contamination of local water supplies due to the lack of proper sanitation and sewage infrastructure.
Show answer & marking scheme

Worked solution

Rapid urbanisation in emerging cities often outpaces infrastructure development. Informal settlements (slums) lack proper municipal sewage systems, resulting in raw sewage and untreated waste being discharged directly into local rivers and streams, causing severe water contamination.

Marking scheme

Award 1 mark for the correct option (D).
Question 5 · Short Structured
2.8 marks
Explain one reason why suburbanisation has occurred in many UK cities.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying a valid reason for suburbanisation, plus 2 further marks for development. For example: Improved transport networks, such as commuter rail or motorways (1 mark), make it easier and faster for people to travel to work (1 mark), allowing them to live further from the city centre where housing is cheaper and larger (1 mark).

Marking scheme

Award 1 mark for a valid reason identified. Award 1 mark for initial explanation showing how this enables or drives movement. Award 1 mark for further development linking it to suburbanisation benefits. Accept any other valid reason such as cheaper land prices, perception of lower crime, or rise of out-of-town retail/business parks.
Question 6 · Short Structured
2.8 marks
Explain one way that green spaces can make an urban area more sustainable.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying a way green spaces contribute to sustainability, plus 2 further marks for explaining how this benefits the urban area. For example: Urban parks and green roofs absorb rainwater through soils and vegetation (1 mark), which reduces surface runoff (1 mark). This lowers the risk of flash flooding in the city, protecting infrastructure for the future (1 mark).

Marking scheme

Award 1 mark for identifying a valid way (e.g., absorbing rainwater, improving air quality, cooling the city). Award 1 mark for explanation of the process. Award 1 mark for linking to long-term sustainability (e.g., flood reduction, health benefits, biodiversity protection).
Question 7 · Short Structured
2.8 marks
Explain one limitation of using Gross National Income (GNI) per capita as a measure of development.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying a limitation of GNI per capita, plus 2 further marks for development. For example: GNI per capita is a country-wide average (1 mark) which hides inequalities between the very rich and the very poor (1 mark). This means it does not show the true quality of life or poverty levels of most citizens (1 mark).

Marking scheme

Award 1 mark for a valid limitation identified (e.g., it is an average, hides regional variations, ignores the informal economy, does not measure non-economic factors like health/education). Award 1 mark for explaining how this occurs. Award 1 mark for showing how it reduces the indicator's usefulness as a measure of development.
Question 8 · Short Structured
2.8 marks
Explain one advantage of being a member of a trading bloc for an emerging country.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying an advantage of trading bloc membership, plus 2 further marks for explanation. For example: Members of a trading bloc benefit from the removal of trade barriers like tariffs (1 mark). This makes exports from the emerging country cheaper and more competitive in other member states (1 mark), which increases industrial production and creates manufacturing jobs (1 mark).

Marking scheme

Award 1 mark for identifying a valid advantage (e.g., removal of tariffs, access to a larger market, increased political security, easier migration of skilled labour). Award 1 mark for explaining how this advantage works. Award 1 mark for linking this directly to the economic or social development of the emerging country.
Question 9 · Short Structured
2.8 marks
Explain one reason why global water consumption has increased rapidly over the last 50 years.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying a reason for increased water consumption, plus 2 further marks for development. For example: Economic development has led to rising household incomes globally (1 mark). This allows more people to afford water-intensive appliances like dishwashers and showers (1 mark), which increases overall domestic water demand per person (1 mark).

Marking scheme

Award 1 mark for a valid reason identified (e.g., global population growth, industrialisation, expansion of irrigated agriculture, rising standards of living/incomes). Award 1 mark for explaining how this increases water demand. Award 1 mark for further development linking it to the rapid global rise over the 50-year period.
Question 10 · Short Structured
2.8 marks
Explain one environmental benefit of transitioning to wind energy instead of fossil fuels.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying an environmental benefit, plus 2 further marks for development. For example: Wind energy does not release greenhouse gases like carbon dioxide during electricity generation (1 mark). This reduces the enhanced greenhouse effect (1 mark), which helps mitigate the rise in global temperatures and extreme weather events (1 mark).

Marking scheme

Award 1 mark for a valid environmental benefit (e.g., reduction in greenhouse gas emissions, reduction in air pollution, no extraction damage to landscapes). Award 1 mark for explaining how transitioning to wind achieves this. Award 1 mark for further development linking it to broader ecological benefits (e.g., mitigation of climate change, improvement in human/animal health due to cleaner air).
Question 11 · Short Structured
2.8 marks
Explain one negative impact of large-scale water transfer schemes.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying a negative impact, plus 2 further marks for explanation. For example: Large-scale water transfer schemes require the construction of dams and reservoirs which flood large areas of land in the donor region (1 mark). This destroys terrestrial habitats and disrupts river ecology (1 mark), leading to a significant loss of local biodiversity (1 mark).

Marking scheme

Award 1 mark for identifying a valid negative impact (e.g., ecological disruption in the donor area, displacement of communities, high financial costs of construction, potential political conflicts). Award 1 mark for explaining how the scheme causes this impact. Award 1 mark for further development of the consequence.
Question 12 · Short Structured
2.8 marks
Explain one reason why rapid population growth leads to challenges in managing waste in megacities.
Show answer & marking scheme

Worked solution

Award 1 mark for identifying a reason, plus 2 further marks for development. For example: The growth of the population often outpaces the development of official municipal services (1 mark). This leads to the expansion of informal settlements where narrow, unpaved roads make physical access for waste collection vehicles impossible (1 mark). As a result, waste accumulates in public areas, increasing the spread of diseases (1 mark).

Marking scheme

For a named major city in a developing or emerging country, assess the success of one or more strategies used to improve the quality of life for its residents.
Show answer & marking scheme

Worked solution

An exemplar response focusing on Rio de Janeiro, Brazil (Favela-Bairro Project):

The Favela-Bairro Project (Slum to Neighbourhood) is a social integration scheme implemented in Rio de Janeiro to improve the quality of life in favelas like Complexo do Alem\u00e3o.

AO2 (4 marks) - Knowledge and Understanding:
* Strategies included paving roads, installing water and sewage pipes, building new health clinics and schools, and installing a cable car system to connect residents to the city center and employment hubs.
* Security was addressed through the introduction of Pacifying Police Units (UPPs) to reduce drug-related crime.

AO3 (4 marks) - Assessment/Evaluation:
* Successes: The project led to a tangible improvement in sanitation and health, reducing water-borne diseases. The cable car dramatically reduced commute times, helping residents access jobs. Standard of living increased as property values rose, and some residents opened formal small businesses.
* Limitations/Failures: The scheme has not been rolled out to all favelas due to a lack of funding ($1 billion budget was insufficient). Some infrastructure has fallen into disrepair because of poor maintenance. Additionally, rising rents caused by gentrification have forced some poorer residents out. The UPP strategy has faced criticism for police brutality, and drug gangs have returned to some areas.

Conclusion:
Overall, while the Favela-Bairro project has successfully transformed infrastructure and connectivity for many, its success is limited by funding shortages and its inability to address the root socioeconomic inequalities across the entire city.

Marking scheme

For a named developing or emerging country, assess the social and environmental impacts of a top-down development project.
Show answer & marking scheme

Worked solution

An exemplar response focusing on the Sardar Sarovar Dam on the Narmada River in India:

The Sardar Sarovar Dam is a massive top-down multi-purpose development scheme aimed at boosting India's economic growth through hydroelectric power and irrigation.

AO2 (4 marks) - Knowledge and Understanding:
* Social impacts: The dam was designed to provide clean drinking water to over 30 million people in drought-prone areas like Gujarat and Rajasthan. It also generates electricity for homes and industries. However, building the reservoir flooded vast areas, displacing over 300,000 people, mostly indigenous tribal groups (Adivasis), who were forced to relocate without adequate compensation.
* Environmental impacts: The dam provides clean, renewable hydroelectric energy, reducing greenhouse gas emissions. However, the creation of the reservoir flooded 37,000 hectares of forest and agricultural land, destroying ecosystems and reducing biodiversity. Downstream flow has been altered, impacting fisheries and causing coastal erosion.

AO3 (4 marks) - Assessment/Evaluation:
* Assessment of positive impacts: From a national development perspective, the project successfully secured water for agriculture and municipal use, significantly improving crop yields (food security) and supporting industrial growth.
* Assessment of negative impacts: However, the local human and ecological cost has been devastating. The failure to properly resettle and compensate displaced communities created severe social marginalisation. The environmental loss of forest and fertile land is irreversible.

Conclusion:
While the project successfully achieved its top-down macroeconomic goals of securing energy and water resources, this came at an extremely high local social and environmental cost, disproportionately affecting the poorest rural populations.

Marking scheme

**Marking Criteria:**

  1. A.It will cause prolonged summer droughts that permanently dry out the soils.
  2. B.It will decrease the rate of urbanisation and runoff in river catchments.
  3. C.It is projected to increase the frequency and intensity of extreme rainfall events.
  4. D.It will lead to a global drop in sea levels, increasing the gradient of river channels.
Show answer & marking scheme

Worked solution

Climate change is projected to increase the frequency and intensity of heavy, extreme rainfall events in the UK. When intense rain falls on saturated ground, it quickly enters river channels as surface runoff, causing rapid increases in discharge and severe flooding.

Marking scheme

Award 1 mark for the correct option (c). Any other response receives 0 marks.
Question 4 · Short Structured
2.5 marks
Explain one reason why it is important to select an appropriate sampling strategy when investigating river channel velocity.
Show answer & marking scheme

Worked solution

An appropriate sampling strategy is critical because river velocity is not uniform; it varies significantly across a river cross-section due to friction with the bed and banks. For example, using systematic sampling (such as measuring at 10% increments across the channel width) ensures that both the slower shallow edges and the faster-flowing deep pools are represented. This prevents personal bias in choosing where to measure, ensuring that the final average velocity calculated is reliable and geographically representative.

Marking scheme

Award 1 mark for identifying the core reason, such as ensuring representative data or avoiding bias (1 mark). Award 1 mark for explaining how the strategy is applied to river features, such as taking measurements at regular intervals across the width to capture variations caused by friction (1 mark). Award 0.5 marks for explaining the impact on the investigation, such as ensuring the final calculated average velocity is valid and accurate (0.5 marks).
Question 5 · Short Structured
2.5 marks
Explain one limitation of using a float (such as an orange or tennis ball) to measure river velocity.
Show answer & marking scheme

Worked solution

Floats sit on the water surface, meaning they only measure surface velocity rather than the velocity throughout the water column. Furthermore, floats can easily be affected by wind, which may artificially accelerate or decelerate them, or they can get caught in surface debris or eddies near the banks. This results in inaccurate measurements that do not reflect the true mean velocity of the river.

Marking scheme

Award 1 mark for identifying the limitation, such as only measuring surface velocity or being affected by external factors like wind or debris (1 mark). Award 1 mark for explaining the physical or mechanical issue, such as surface water flowing faster due to less friction or wind pushing the float out of the main current (10 mark). Award 0.5 marks for linking to data accuracy, such as resulting in an overestimation of the average channel velocity (0.5 marks).
Question 6 · Short Structured
2.5 marks
Explain one reason why using a pilot study is beneficial when preparing to carry out a questionnaire in an urban area.
Show answer & marking scheme

Worked solution

A pilot study is a small-scale trial run of the questionnaire. It allows the researcher to identify if any questions are confusing, offensive, or too open-ended. By testing and refining the questions beforehand, the researcher can make necessary adjustments, saving valuable time and ensuring that the actual data collected is consistent, relevant, and easy to analyze.

Marking scheme

Award 1 mark for identifying the purpose of a pilot study, such as testing and refining the questionnaire design (10 mark). Award 1 mark for explaining how this is achieved, such as identifying ambiguous phrasing or questions that people refuse to answer (1 mark). Award 0.5 marks for explaining the benefit to the fieldwork outcome, such as leading to higher quality, more reliable data when the actual questionnaire is rolled out (0.5 marks).
Question 7 · Short Structured
2.5 marks
Explain one advantage of using a decibel meter app on a smartphone rather than a qualitative description to measure environmental quality in an urban area.
Show answer & marking scheme

Worked solution

Qualitative descriptions of noise (such as 'quiet' or 'very loud') are highly subjective and vary based on an individual's perception. In contrast, a decibel meter app measures sound pressure levels in decibels (dB), yielding objective, quantitative data. This allows researchers to make precise, reliable comparisons between sites and perform statistical tests, which improves the scientific validity of the environmental quality assessment.

Marking scheme

Award 1 mark for identifying the advantage, such as providing quantitative, objective data rather than subjective opinions (1 mark). Award 1 mark for explaining why this is better than qualitative methods, such as eliminating personal bias as different students have different perceptions of loudness (1 mark). Award 0.5 marks for explaining the advantage in data processing, such as enabling precise comparisons and statistical testing between fieldwork sites (0.5 marks).
Question 8 · Short Structured
2.5 marks
Explain one way that the development of brownfield sites can help to reduce the UK's housing shortage while protecting the environment.
Show answer & marking scheme

Worked solution

Brownfield sites are abandoned or underused industrial lands within existing urban boundaries. Redeveloping them for residential housing directly targets the housing shortage where infrastructure and demand already exist. This protects the environment because it diverts development pressure away from greenfield sites and the green belt, thereby preserving rural ecosystems, agricultural land, and biodiversity.

Marking scheme

Award 1 mark for identifying how brownfield development works, such as utilizing existing derelict urban land for housing (1 mark). Award 1 mark for explaining the environmental benefit, such as preventing the development of greenfield sites and protecting the green belt (1 mark). Award 0.5 marks for connecting it to the outcome, such as conserving rural ecosystems and biodiversity from urban sprawl (0.5 marks).
Question 9 · Short Structured
2.5 marks
Explain one challenge that the UK faces in managing its future water supply due to population growth and climate change.
Show answer & marking scheme

Worked solution

The UK's water supply and demand are geographically mismatched. The highest population density and fastest growth are in London and the South East, which receive the lowest annual rainfall. Conversely, the highest rainfall occurs in the north and west, where population density is lower. Climate change exacerbates this by causing hotter, drier summers, increasing water stress in the South East and requiring costly water transfer infrastructure or strict demand management.

Marking scheme

Award 1 mark for identifying the core challenge, such as geographical mismatch between water supply and population demand (1 mark). Award 1 mark for explaining the impact of climate change or population, such as hotter, drier summers reducing reservoir levels in the South East where demand is highest (1 mark). Award 0.5 marks for explaining the resulting management problem, such as requiring expensive infrastructure like pipelines or causing severe water restrictions (0.5 marks).
Question 10 · Short Structured
2.5 marks
Explain one economic benefit of developing sustainable transport schemes, such as cycle superhighways, in major UK cities.
Show answer & marking scheme

Worked solution

By encouraging commuters to switch from private cars to cycling, sustainable transport schemes significantly lower the volume of vehicles on the road. This reduces traffic congestion, meaning commercial deliveries and public transit move more quickly. The economic benefit is a reduction in lost working hours and fuel costs for businesses, which boosts urban productivity and increases the overall economic efficiency of the city.

Marking scheme

Award 1 mark for identifying an economic benefit, such as reduction in congestion, faster journey times, or lower fuel costs (1 mark). Award 1 mark for explaining how this benefits workers or businesses, such as workers spending less time stuck in traffic, leading to fewer lost working hours (1 mark). Award 0.5 marks for linking to the wider economic impact, such as boosting business productivity and saving transport costs (0.5 marks).
Question 11 · Short Structured
2.5 marks
Explain one way in which national park authorities in the UK can manage the negative environmental impacts of tourism.
Show answer & marking scheme

Worked solution

High visitor numbers in popular areas like the Lake District or Peak District lead to severe footpath erosion and soil compaction. To manage this, national park authorities use stone-pitching (laying local stone to create clear, hard-wearing paths). This encourages walkers to stay on the main path, which successfully protects the surrounding delicate vegetation and prevents wider soil erosion and landscape scarring.

Marking scheme

Award 1 mark for identifying a management strategy, such as footpath restoration, stone-pitching, or zoning areas (1 mark). Award 1 mark for explaining how the strategy is implemented, such as using local stone to construct a durable path that encourages walkers to stick to the route (1 mark). Award 0.5 marks for explaining the environmental benefit, such as preventing soil compaction, erosion, and destruction of nearby habitats (0.5 marks).
Question 12 · Short Structured
2 marks
Explain one challenge that the UK's ageing population will present for healthcare services.
Show answer & marking scheme

Worked solution

An ageing population means there are more elderly people who typically suffer from complex, long-term health conditions (1 mark). This leads to a higher volume of hospital admissions and longer stays, which increases pressure on NHS staff and resources (1 mark).

Marking scheme

Award 1 mark for identifying a valid challenge, and 1 mark for explaining/developing how it affects healthcare services. e.g. Increased demand on GP surgeries (1) because elderly people are more likely to suffer from multiple, ongoing health issues (1). Accept any other reasonable responses.
Question 13 · Short Structured
3 marks
Explain one advantage of using systematic sampling when choosing locations to measure environmental quality in an urban fieldwork investigation.
Show answer & marking scheme

Worked solution

Systematic sampling means locations are selected at regular intervals (e.g., every 100 metres) along a transect (1 mark). This removes any subjective bias by the researcher when choosing where to record environmental quality (1 mark), ensuring that the collected data is highly representative of the changes across the urban area (1 mark).

Marking scheme

Award 1 mark for describing/identifying a characteristic advantage of systematic sampling (1), and up to 2 further marks for explaining how this benefits the quality of the fieldwork data (1+1). e.g. Points are selected at equal intervals (1) which prevents the researcher choosing only clean or dirty areas (1), making the final environmental quality index map more representative and accurate (1).

Assess the view that developing brownfield sites is the most sustainable solution to meet the UK’s growing demand for housing.
Show answer & marking scheme

Worked solution

Introduction
The UK faces a significant housing crisis driven by a growing, ageing, and urbanising population. Resolving this shortage sustainably requires balancing social needs (affordable housing), economic viability, and environmental preservation. Developing brownfield sites (previously used land in urban areas) is often championed as the ideal solution, but it presents distinct challenges compared to greenfield development (untouched rural/semi-rural land).

Arguments for developing brownfield sites (Environmental & Social Sustainability)
1. Environmental preservation: Building on brownfield sites protects the greenfield land, agricultural fields, and the Green Belt. This prevents the loss of natural ecosystems, biodiversity, and carbon sinks.
2. Urban regeneration: Developing derelict or abandoned urban areas improves the local environment, reduces urban decay, and removes eyesores, which can lower crime rates and boost community pride.
3. Existing infrastructure: Brownfield sites are already connected to major road networks, public transport, electricity, water, and sewage systems. This significantly reduces the carbon footprint and financial cost associated with building new infrastructure.

Arguments against relying solely on brownfield sites / Arguments for greenfield sites
1. High cleanup costs and economic viability: Many brownfield sites (especially former industrial zones) suffer from toxic contamination. Decontamination is extremely expensive and time-consuming, making projects less economically attractive to developers or resulting in fewer affordable housing units being built.
2. Location and space constraints: Brownfield sites are often small, irregular, or located in inner-city areas with high congestion and air pollution. This limits the scale of housing that can be built and may not suit families who prefer suburban open spaces.
3. Insufficient supply: The sheer volume of demand for new homes (estimated at 300,000 per year in England) cannot be met by brownfield sites alone, as many are not in areas where the demand is highest (e.g., the South East of England).

Conclusion
In conclusion, while brownfield development is highly sustainable in terms of land preservation and urban renewal, it is not a complete solution on its own. The high costs of decontamination and the mismatch between where brownfield land is available and where housing is most needed limit its effectiveness. Therefore, a truly sustainable approach must combine brownfield regeneration with highly planned, sustainable greenfield developments (such as 'garden villages' or sustainable urban extensions) to meet the UK’s housing needs without causing environmental degradation.
