Answer three questions in total, one from each section.
15 Question · 93 marks
Question 1 · Thematic Structured Short Answer
6 marks
Explain the differences between constructive and destructive waves and how they affect the profile of a beach.
Show answer & marking scheme

Worked solution

Constructive waves are characterised by low frequency (6-9 per minute), low wave height, and long wavelength. Their swash is stronger than their backwash, leading to net deposition of sediment, which builds up the beach and forms features like berms, creating a wider, flatter profile. Destructive waves are characterised by high frequency (11-15 per minute), high wave height, and short wavelength. Their backwash is stronger than their swash, causing net erosion of sediment, which removes material from the beach and creates a steeper, narrower profile with offshore bars.

Marking scheme

Award up to 4 marks for wave characteristics (e.g., frequency, height, swash vs. backwash strength). Award up to 3 marks for beach profile impacts (e.g., deposition/building, erosion/narrowing, formation of berms/bars). Max 6 marks in total.
Question 2 · Thematic Structured Short Answer
6 marks
Explain the physical conditions required for the growth and development of coral reefs.
Show answer & marking scheme

Worked solution

Coral polyps have specific environmental needs to grow and build reefs: 1) Warm water temperatures, ideally between 20°C and 30°C, as they cannot survive in cold water. 2) Shallow depths, typically less than 50-60 meters, to allow sufficient sunlight to reach the symbiotic zooxanthellae algae for photosynthesis. 3) Clear, sediment-free water, because suspended sediment blocks light and can smother the polyps. 4) Normal marine salinity levels, as corals cannot survive in fresh or highly saline water. 5) Well-oxygenated water, often provided by strong wave action, which also brings a constant supply of microscopic food. 6) A solid, rocky sea floor substrate for the polyps to attach themselves.

Marking scheme

Award 1 mark for each physical condition explained (up to 6 marks): - Water temperature 20-30°C / warm water (1 mark) - Shallow water / less than 50-60m depth (1 mark) - Sunlight penetration / for photosynthesis (1 mark) - Clear / sediment-free water (1 mark) - Normal marine salinity / salt water (1 mark) - Oxygenated water / strong waves (1 mark) - Hard / rocky substrate (1 mark)
Question 3 · Thematic Structured Short Answer
6 marks
Explain how plate movement leads to volcanic eruptions at destructive (convergent) plate boundaries.
Show answer & marking scheme

Worked solution

At a destructive plate boundary, convection currents in the mantle drive two plates towards each other. The denser oceanic plate is forced downwards beneath the lighter continental plate in a process called subduction. As the oceanic plate descends into the subduction zone, intense friction, pressure, and geothermal heat cause it to melt, forming magma. Water carried down with the subducted plate also lowers the melting point of the surrounding mantle. This magma is less dense than the solid mantle and crust above it, causing it to rise through cracks, faults, and weaknesses in the continental crust. When it reaches the surface, pressure is released, resulting in an explosive volcanic eruption.

Marking scheme

Award marks for explained steps of the process: - Plates move towards each other/converge (1 mark) - Subduction of denser oceanic plate beneath continental plate (1 mark) - Mention of subduction zone/deep ocean trench (1 mark) - Friction/heat/pressure melts the subducted plate (1 mark) - Magma is less dense and rises (1 mark) - Magma travels through cracks/weaknesses/fissures in the crust (1 mark) - Pressure release causes explosive eruption (1 mark). Max 6 marks.
Question 4 · Thematic Structured Short Answer
6 marks
Explain how the design and location of a Stevenson screen ensure that the weather instruments inside record accurate air temperature.
Show answer & marking scheme

Worked solution

A Stevenson screen is designed to measure shade temperature accurately by isolating instruments from direct environmental influences. 1) It is painted white to reflect direct solar radiation, preventing the inside from absorbing heat. 2) It is constructed of wood, which is a poor heat conductor, preventing external heat from transferring inside. 3) It features double-slatted louvred sides that allow free air flow (ventilation) so the temperature of the air circulating inside is identical to the ambient air temperature, while still shielding instruments from direct wind and sun. 4) It is raised on a metal stand to about 1.25 to 1.5 meters above the ground to prevent heat radiating from the ground surface. 5) It is placed on a grass-covered surface rather than tarmac or concrete to prevent high heat absorption. 6) It is situated in an open area away from tall trees and buildings to avoid shadows, wind blocks, and heat from artificial structures.

Marking scheme

Award 1 mark for each design feature linked to its purpose (up to 6 marks): - White paint reflects solar radiation (1 mark) - Wood material acts as a poor conductor/insulator (1 mark) - Louvred/slatted sides allow ventilation/air flow (1 mark) - Double roof insulates against direct overhead sun (1 mark) - Raised 1.25m-1.5m to avoid ground radiation (1 mark) - Sited on grass to avoid heat absorption from artificial surfaces (1 mark) - Placed in open area to avoid shade/obstacles (1 mark).
Question 5 · Thematic Structured Short Answer
6 marks
Explain the social and economic challenges faced by international migrants in their destination countries.
Show answer & marking scheme

Worked solution

International migrants encounter several significant challenges upon arrival: 1) Language barriers: if they do not speak the local language, it is highly difficult to find work, navigate services, or integrate. 2) Employment challenges: qualifications from their home country are often not recognized, forcing them into low-paid, unskilled, or manual labor, and they may experience wage exploitation. 3) Housing difficulties: high costs and discrimination can relegate them to overcrowded, poor-quality accommodation or informal settlements. 4) Social exclusion and discrimination: they may face xenophobia, racism, and social isolation from the host population. 5) Access to services: legal or language issues can make it difficult to access healthcare, education, or financial services. 6) Cultural shock: adapting to new customs, food, and laws while experiencing homesickness.

Marking scheme

Award 1 mark for each explained challenge (up to 6 marks): - Language barriers limit communication/integration (1 mark) - Unrecognized qualifications lead to underemployment/low-pay (1 mark) - Exploitation/long hours/poor working conditions (1 mark) - High housing costs lead to overcrowding/poor accommodation (1 mark) - Discrimination/racism/xenophobia from host population (1 mark) - Difficulty accessing public services like healthcare or schools (1 mark) - Cultural shock/homesickness/loss of support network (1 mark).
Question 6 · Thematic Structured Short Answer
6 marks
Explain why rural areas in less economically developed countries (LEDCs) often experience high rates of out-migration.
Show answer & marking scheme

Worked solution

High rates of out-migration from rural areas in LEDCs are driven by several push factors: 1) Economic factors: there is a lack of diverse, well-paying job opportunities, with most people relying on subsistence agriculture which is physically demanding and yields low income. 2) Agricultural changes: increasing mechanization of farms reduces the demand for manual labor, leaving many young workers unemployed. 3) Natural hazards and food insecurity: droughts, floods, or pests can devastate crops, leading to severe food shortages, malnutrition, and loss of income. 4) Poor services: rural areas often suffer from a lack of secondary schools, universities, and hospitals, forcing people to move to obtain education or healthcare. 5) Poor infrastructure: a lack of electricity, clean piped water, and paved roads reduces the quality of life. 6) Land fragmentation: high population growth means family plots are divided into smaller, less viable parcels of land with each generation.

Marking scheme

Award 1 mark for each explained push factor (up to 6 marks): - Lack of job opportunities / low income from farming (1 mark) - Farm mechanization reducing labor demand (1 mark) - Crop failure/natural hazards (droughts/floods) leading to food insecurity (1 mark) - Poor healthcare/medical facilities (1 mark) - Poor educational facilities/lack of schools (1 mark) - Lack of basic infrastructure like clean water, electricity, or roads (1 mark) - Population pressure leading to land fragmentation/smaller farm plots (1 mark).
Question 7 · Thematic Structured Short Answer
6 marks
Explain how physical factors influence the site and growth of rural settlements.
Show answer & marking scheme

Worked solution

Physical factors are crucial in determining where rural settlements are established (sited) and how they expand: 1) Water supply: settlements are often sited near rivers or springs (wet-point sites) to ensure a reliable source of water for drinking, washing, and farming. 2) Avoidance of flooding: in low-lying wet areas, settlements are sited on elevated ground (dry-point sites) to prevent water damage. 3) Soil fertility: rural communities rely on agriculture, so they are sited near rich, fertile alluvial or volcanic soils to ensure productive crop yields. 4) Relief of the land: flat or gently sloping land is preferred because it makes constructing dwellings, roads, and farming much easier than steep slopes. 5) Aspect and shelter: in temperate areas, settlements may be sited on south-facing slopes (in the Northern Hemisphere) to maximize sunlight and warmth, and in valleys to seek shelter from strong winds. 6) Defence: natural defensive features such as hills, cliffs, or bends in rivers were historically chosen to protect against attacks.

Marking scheme

Award 1 mark for each physical factor explained with its influence on site or growth (up to 6 marks): - Wet-point sites/water supply for daily needs/irrigation (1 mark) - Dry-point sites on higher ground to avoid flooding (1 mark) - Fertile soils to support agricultural development/food source (1 mark) - Flat/gently sloping relief makes building/farming easier (1 mark) - Shelter/aspect (e.g., south-facing slopes for warmth/sunlight) (1 mark) - Defensive features (hills, river loops) for protection (1 mark).
Question 8 · Thematic Structured Short Answer
6 marks
Explain how the locational factors of high-technology industries differ from those of heavy manufacturing industries.
Show answer & marking scheme

Worked solution

The locational requirements of high-technology industries and heavy manufacturing differ significantly: 1) Labor: High-tech industries require highly skilled, professional workers, so they locate near universities and research parks. Heavy manufacturing requires a large supply of manual or semi-skilled labor. 2) Transport: High-tech products are lightweight and high-value, so they depend on proximity to international airports and major highways. Heavy manufacturing involves bulky, heavy raw materials and finished goods, making proximity to deep-water ports, railways, and heavy-freight networks essential to minimize transport costs. 3) Raw Materials: High-tech is 'footloose' and not tied to raw material sites. Heavy manufacturing is weight-losing and often locates directly near raw material sources (e.g., coal, iron ore) or coastal import terminals. 4) Site and Environment: High-tech companies prefer attractive, clean greenfield sites in science parks to attract skilled professionals. Heavy manufacturing requires vast areas of cheap, flat land and is often located in industrial zones or brownfield sites due to pollution, noise, and space requirements.

Marking scheme

Award up to 6 marks for detailed comparisons. Must address both sectors to get full marks: - Highly skilled labor/universities for high-tech vs manual labor for heavy manufacturing (1 mark) - Airports/light transport for high-tech vs ports/rail/bulk transport for heavy manufacturing (1 mark) - Footloose/no raw material ties for high-tech vs located near bulky raw materials for heavy manufacturing (1 mark) - Greenfield/clean environment for high-tech vs brownfield/industrial zones for heavy manufacturing (1 mark) - Small spatial footprint/high-quality infrastructure for high-tech vs large flat cheap land requirement for heavy manufacturing (1 mark).
Question 9 · Thematic Structured Short Answer
6 marks
Explain the physical processes that lead to the formation of a spit along a coastline.
Show answer & marking scheme

Worked solution

1. The prevailing wind blows at an angle to the shoreline, driving the swash to carry sediment up the beach at an angle. 2. Gravity pulls the backwash straight down the beach slope at a 90-degree angle, creating a zig-zag movement of sediment known as longshore drift. 3. At a bend in the coastline or a river estuary, the shoreline changes direction, but longshore drift continues to transport material in the original direction. 4. Due to the drop in wave energy in the deeper, sheltered water, the sediment is deposited. 5. This accumulation of sand and shingle builds up above the high-tide mark to form a long, narrow spit extending out to sea. 6. Occasional shifts in wind and wave direction can bend the seaward end of the spit inland to form a hook, and fine silt accumulates in the calm water behind the spit to form a salt marsh.

Marking scheme

Award 1 mark for each valid explanatory point up to 6 marks. Max 1 mark for naming longshore drift without explaining how it operates. Max 1 mark for explaining the role of wind/wave changes in creating a hooked end. Max 1 mark for explaining the development of a salt marsh behind the spit.
Question 10 · Thematic Structured Short Answer
6 marks
Explain both the positive and negative impacts of large-scale emigration (out-migration) on the country of origin.
Show answer & marking scheme

Worked solution

Positive impacts: 1. Remittances: Migrants send money back home to their families, which increases household income and boosts the local economy through increased spending. 2. Decreased unemployment: The departure of active labor reduces competition for jobs, lowering unemployment rates in the origin country. 3. Reduced pressure on resources: With fewer people, there is less demand on public services like healthcare, schools, and infrastructure. Negative impacts: 1. Brain drain: Highly skilled, educated professionals (such as doctors, nurses, and engineers) leave the country, reducing the quality of local services and slowing economic growth. 2. Loss of active workforce: The emigration of young, working-age people leads to labor shortages in agriculture, construction, or industries. 3. High dependency ratio: As mostly young adults leave, the remaining population becomes disproportionately composed of elderly individuals and young children, increasing the economic burden on the state and the remaining workers.

Marking scheme

Award 1 mark for each well-explained impact. Candidates must include at least one positive and one negative impact to achieve full marks. Max 4 marks if only positive or only negative impacts are discussed.
Question 11 · Thematic Structured Short Answer
6 marks
Explain why high population densities are often found in areas surrounding active volcanoes.
Show answer & marking scheme

Worked solution

1. Fertile agricultural land: Weathered volcanic ash and lava release essential minerals and nutrients into the soil, allowing high crop yields and making farming highly profitable. 2. Geothermal energy: The heat from volcanic systems can be harnessed to generate cheap, clean, renewable geothermal electricity and hot water for local residents. 3. Tourism opportunities: Dramatic volcanic landscapes, hot springs, and craters attract domestic and international tourists, creating numerous jobs in hotels, restaurants, guiding, and transport. 4. Valuable mineral resources: Volcanic activity deposits valuable minerals such as sulfur, copper, gold, and diamonds, which can be extracted by mining companies, creating local employment. 5. Social and economic constraints: Some communities have lived in volcanic areas for generations and hold strong ancestral connections to the land, while others are too poor to afford the cost of relocating to safer regions. 6. Monitoring and protection: Modern volcanic observatories provide early warnings, giving residents confidence that they can evacuate safely before a major eruption occurs.

Marking scheme

Award 1 mark for each fully explained factor up to 6 marks. Do not award marks for simple lists (e.g., 'soil and jobs' receives 1 mark unless developed into an explanation of how they benefit local residents).
Question 12 · Thematic Structured Short Answer
6 marks
Explain how the design and location of a Stevenson Screen ensure that weather instruments inside record accurate air temperatures.
Show answer & marking scheme

Worked solution

Design features: 1. Painted white: This reflects incoming solar radiation, preventing the box from absorbing heat and ensuring that the air temperature inside does not rise above actual ambient levels. 2. Slatted / louvred sides: These allow air to circulate freely through the screen, ensuring that the instruments measure the temperature of the moving air rather than trapped, stagnant air. 3. Double-layered roof: The space between the roof layers provides insulation, blocking overhead heat from the sun from penetrating down to the instruments. Location features: 1. Raised on legs (approx. 1.21 to 1.5 meters): This ensures the instruments measure true air temperature, avoiding the heat radiated or conducted from the ground surface. 2. Placed over grass rather than concrete: Concrete absorbs and radiates substantial amounts of heat, whereas grass absorbs heat naturally without creating artificial temperature spikes. 3. Located in an open area: It is kept away from buildings, trees, and fences to prevent artificial shade or wind blockages from skewing the readings.

Marking scheme

Award 1 mark for each correct explanation of a design or location feature. Candidates must include at least two design features and two location features to achieve full marks. Max 4 marks if only design or only location features are covered.
Question 13 · Thematic Case Study
7 marks
For a named international migration flow you have studied, describe the positive and negative impacts of this migration on the destination country.
Show answer & marking scheme

Worked solution

Case Study: Mexico to the United States (USA)

Positive impacts on the destination country (USA):
- Migrants fill labor shortages in low-skilled, low-wage sectors such as agriculture (e.g., fruit picking in California), construction, and the hospitality industry. This keeps production costs down and lowers prices for consumers.
- The influx of diverse cultures enriches the social fabric of American cities, introducing new foods, music, language, and cultural festivals (such as Cinco de Mayo).
- Migrants contribute significantly to the local economy by purchasing goods and paying taxes (such as sales tax and property tax), which funds public services.

Negative impacts on the destination country (USA):
- Increased pressure on public services, particularly healthcare and education, in border states like California, Texas, and Arizona. Public schools may face extra costs to support English as a Second Language (ESL) programs.
- High levels of undocumented migration lead to significant government expenditure on border security, patrol forces, and detention infrastructure.
- Social and political tensions can arise, with some native-born citizens claiming that migration suppresses local wages or alters the cultural identity of local communities.

Marking scheme

Level 1 (1–3 marks):
- Simple, generic statements describing impacts without specific detail or development.
- E.g., "Migrants do low-paid jobs." "Schools become overcrowded." "They bring their food and culture."
- Note: Max 3 marks if no case study is named or if the chosen case study is inappropriate.

Level 2 (4–6 marks):
- Developed statements explaining how or why these impacts occur.
- E.g., "Migrants work in the agricultural sector picking crops in states like California, which helps keep food prices low for US consumers because they accept lower wages than local workers." (Developed positive impact)
- E.g., "Increased numbers of non-English speaking children put a strain on school budgets in border states because extra funding is needed to hire specialist ESL teachers." (Developed negative impact)
- Note: Max 5 marks if only positive or only negative impacts are described.

Level 3 (7 marks):
- Comprehensive response containing at least two fully developed positive points and two fully developed negative points.
- Must include place-specific details or data (e.g., specific state names like California/Texas, statistics, or details unique to the Mexico-USA migration corridor).
Question 14 · Thematic Case Study
7 marks
For a named volcanic eruption you have studied, explain the causes of the eruption and describe its effects on people and the environment.
Show answer & marking scheme

Worked solution

Case Study: Eyjafjallajökull Eruption, Iceland (\(2010\))

Causes:
- Iceland is situated on the Mid-Atlantic Ridge, a constructive (divergent) plate boundary where the North American and Eurasian tectonic plates are pulling apart.
- As the plates move away from each other, magma rises from the mantle to fill the gap, creating a shield volcano.
- In April \(2010\), basaltic magma erupted directly underneath the Gigjökull glacier. The interaction of \(1200\)°C molten rock with ice caused rapid cooling, fragmentation of the lava into highly abrasive silica glass particles, and explosive steam-driven eruptions (phreatomagmatic activity).

Effects:
- Environmental: The ash plume rose up to \(9\) km into the atmosphere and drifted south-east across Europe due to jet stream winds. Huge volumes of glacial meltwater (jökulhlaups) flooded local valleys, destroying farmland, bridges, and sections of Iceland's main Route 1 ring road.
- Social/Economic: Local farms downwind of the volcano were heavily blanketed in ash, and livestock had to be kept indoors to prevent fluorine poisoning. Globally, the ash cloud led to the closure of airspace across much of Europe for six days. Over \(100,000\) flights were canceled, leaving millions of travelers stranded and costing the global airline industry an estimated \(1.7\) billion USD in lost revenue.

Marking scheme

Level 1 (1–3 marks):
- Simple, generic statements explaining the cause or describing the effects of a volcanic eruption.
- E.g., "The plates moved apart and let lava out." "Ash covered the area and planes could not fly." "Local people had to wear masks."
- Note: Max 3 marks if no case study is named or if the chosen case study is inappropriate.

Level 2 (4–6 marks):
- Developed statements explaining the tectonic process or detailing the consequences of the eruption.
- E.g., "The eruption occurred at a constructive boundary where the North American and Eurasian plates are moving apart, allowing magma to rise and erupt under an ice cap." (Developed cause)
- E.g., "The volcanic ash drifted over European airspace, causing the cancellation of over \(100,000\) flights because the silica glass in the ash could melt inside and damage jet engines." (Developed effect)
- Note: Max 5 marks if only causes or only effects are covered.

Level 3 (7 marks):
- Comprehensive response explaining both causes and effects (covering both human and environmental impacts).
- Must include specific place-specific details or data (e.g., named tectonic plates, specific dates, cost of damage, names of glaciers/local areas like Gigjökull, or specific flight cancelation figures).
Question 15 · Thematic Case Study
7 marks
For a named factory or industrial zone you have studied, explain how physical and human factors influenced its location.
Show answer & marking scheme

Worked solution

Case Study: Toyota Car Manufacturing Plant, Burnaston, Derby, UK

Physical Factors:
- Flat Land: The factory is located on the flat floodplain of the River Trent valley at Burnaston. This made the construction of a large, single-story assembly plant covering \(110\) hectares physically easier and cheaper than building on sloped ground.
- Room for Expansion: The site was surrounded by greenfield agricultural land, allowing Toyota the physical space to expand its facilities, test track, and storage yards over time.

Human/Economic Factors:
- Transport Links: The plant is built immediately adjacent to the A38 and A50 dual carriageways, which connect directly to the M1 motorway. This allows for rapid transport of completed vehicles to ports and facilitates the 'Just-In-Time' supply chain for components.
- Labor Supply: Derby has a long history of engineering excellence (being the home of Rolls-Royce). This provided Toyota with a large pool of highly skilled, pre-trained engineering labor within commuting distance.
- Government Incentives: The UK government and local councils offered financial grants and helped clear planning permission to attract Toyota to the area, aiming to regenerate the local economy and reduce regional unemployment.

Marking scheme

Level 1 (1–3 marks):
- Simple statements identifying location factors without explanation or development.
- E.g., "It was built on flat land." "It is next to a big road." "There were many workers living nearby."
- Note: Max 3 marks if no case study is named or if the chosen case study is inappropriate.

Level 2 (4–6 marks):
- Developed statements explaining how physical or human factors influenced the location decision.
- E.g., "The factory was built on flat, cheap greenfield land at Burnaston, which made the physical layout of a huge horizontal assembly line possible and reduced initial construction costs." (Developed physical factor)
- E.g., "The site is located next to the A38 and A50 dual carriageways, allowing parts to arrive from suppliers quickly under a 'Just-In-Time' manufacturing system without needing large warehouses." (Developed human factor)
- Note: Max 5 marks if only physical or only human factors are explained.

Level 3 (7 marks):
- Detailed explanation covering both physical and human factors in a balanced way.
- Must include place-specific details (e.g., specific road names like the A38/A50, local city names like Derby/Nottingham, or specific site details like the acreage of the Burnaston site).

Study the coastal data below. At Site A, a limestone cliff has retreated by 18 metres over a monitoring period of 12 years.

(a) Calculate the average annual rate of cliff retreat at Site A. Show your working. [2]

(b) Using geographical terms, describe three differences between constructive and destructive waves. [3]

(c) State three coastal management strategies that could be implemented to protect this cliff from further retreat. [3]
Show answer & marking scheme

Worked solution

(a) To calculate the annual rate of cliff retreat, divide the total retreat distance by the total time period: \( 18 \text{ metres} / 12 \text{ years} = 1.5 \text{ metres per year} \).

(b) Constructive waves are depositional, featuring a powerful swash that pushes sediment up the beach, a weak backwash, long wavelengths, low height, and low frequency. Destructive waves are erosional, with a weak swash, powerful backwash that drags sediment away, short wavelengths, high height, and high frequency.

(c) Coastal management strategies to protect cliffs from erosion include hard engineering techniques such as building concrete sea walls to reflect wave energy, placing rip-rap (large boulders) at the base of the cliff to dissipate wave force, or soft engineering like cliff regrading to reduce slope steepness and prevent landslides.

Marking scheme

Part (a) [2 marks]:
- 1 mark for correct working shown: \( 18 / 12 \).
- 1 mark for correct calculation: 1.5 (must include units: metres per year or m/yr).

Part (b) [3 marks]:
- 1 mark for contrasting swash/backwash characteristics (e.g., constructive has stronger swash than backwash; destructive has stronger backwash than swash).
- 1 mark for contrasting wave dimensions (e.g., constructive are low/flat/long wavelength; destructive are high/steep/short wavelength).
- 1 mark for contrasting wave frequency (e.g., constructive have low frequency/6-8 waves per minute; destructive have high frequency/10-14 waves per minute).

Part (c) [3 marks]:
- 1 mark for each valid hard or soft engineering strategy mentioned (e.g., sea walls, rip-rap/rock armour, groynes, gabions, revetments, cliff regrading, beach nourishment). Max 3 marks.
Question 3 · Thematic Skill Application

Study the following details of an earthquake event. At a distance of 15 km from the epicenter, Settlement P (built on soft alluvial silt) recorded a Modified Mercalli Intensity of VIII, while Settlement Q (built on solid granite bedrock) at the same distance recorded an intensity of V.

(a) Suggest why the shaking intensity was higher at Settlement P than at Settlement Q. [2]

(b) Name the instrument used to record the ground motion of an earthquake, and state the term used to describe the primary point of rupture deep underground where the earthquake originates. [2]

(c) Explain how planning and preparation can reduce the impacts of earthquakes in high-risk urban areas. [4]
Show answer & marking scheme

Worked solution

(a) Shaking intensity is heavily influenced by local geology. Unconsolidated deposits like alluvial silt undergo ground amplification, increasing shaking severity, and can experience liquefaction where wet soil behaves like a liquid. Hard igneous rocks like granite transmit seismic energy much more stably, resulting in lower Mercalli intensity levels.

(b) Earthquakes are recorded using a seismometer (or seismograph). The underground point of origin where the rock breaks is called the focus or hypocentre (the point directly above it on the surface is the epicentre).

(c) Planning and preparation save lives by making buildings and infrastructure resilient (such as utilizing rubber foundations, steel frames, and shatterproof glass), designating safe evacuation spaces, mapping hazard zones to prevent expansion on vulnerable ground, and running educational campaigns so the public knows to 'Drop, Cover, and Hold On'.

Marking scheme

Part (a) [2 marks]:
- 1 mark for stating that soft alluvial silt amplifies seismic waves / causes liquefaction.
- 1 mark for contrast showing that granite bedrock is solid / stable / dampens waves.

Part (b) [2 marks]:

Question 4 · Thematic Skill Application

A student recorded weather observations at a school weather station. The dry-bulb temperature is 20°C, and the wet-bulb temperature is 16°C.

(a) Calculate the wet-bulb depression. [1]

(b) Using the relative humidity principles, if a wet-bulb depression of 4°C at a dry-bulb temperature of 20°C corresponds to a relative humidity of 66%, state the relative humidity. [1]

(c) State three design features of a Stevenson Screen and explain how each feature ensures that air temperature is recorded accurately. [3]

(d) Explain how relief (orographic) rainfall is formed. [3]
Show answer & marking scheme

Worked solution

(a) Wet-bulb depression is calculated by subtracting the wet-bulb temperature from the dry-bulb temperature: \( 20^{\circ}\text{C} - 16^{\circ}\text{C} = 4^{\circ}\text{C} \).

(b) By cross-referencing the dry-bulb temperature of 20°C with the depression value of 4°C on a hygrometer table, the relative humidity is identified as 66%.

(c) A Stevenson Screen protects sensitive instruments from direct external heat sources. The white paint reflects solar radiation, preventing the box from heating up; the louvred (slatted) sides allow ambient air to flow through freely so that air temperature is measured; the double roof provides an insulating layer of air to block conduction of heat from the top.

(d) Relief rainfall occurs when prevailing winds blow moist air from the ocean toward mountains. The air is forced upward. As it rises, adiabatic cooling occurs, water vapour condenses to form cumulus clouds, and rain falls on the windward side, leaving a dry rain shadow on the leeward side.

Marking scheme

- 1 mark for correct calculation: 4°C.

Part (b) [1 mark]:
- 1 mark for correct statement of relative humidity: 66%.

Part (c) [3 marks]:

- Louvres/slats -> allows air to circulate/ventilation [1 mark].
- Double roof -> insulates against heat from above [1 mark].
- Raised off ground (approx. 1.2m) -> avoids heat radiated from ground surface [1 mark].
- Wood construction -> poor conductor of heat [1 mark].

Part (d) [3 marks]:
- 1 mark for stating air is forced to rise over a barrier (mountain/hills).
- 1 mark for stating that rising air cools and condenses (forming clouds).
- 1 mark for stating that rain falls on the windward slope.
Question 5 · Thematic Skill Application

In 2022, Country X (a developing nation) experienced significant migration flows. A total of 55,000 people emigrated from Country X to Country Y (a developed nation), while 5,000 people migrated from Country Y to Country X.

(a) Calculate the net migration for Country X in 2022. State whether this is a net migration gain or loss. [2]

(b) Identify two economic push factors that would lead to high emigration from Country X. [2]

(c) Explain how large-scale outward migration can affect the population structure and economy of the country of origin (source country). [4]
Show answer & marking scheme

Worked solution

(a) Net migration is calculated as Immigration minus Emigration: \( 5,000 \text{ (in-migrants)} - 55,000 \text{ (out-migrants)} = -50,000 \). Since the value is negative, it represents a net migration loss of 50,000 people.

(b) Economic push factors include domestic conditions that drive people to leave, such as severe unemployment, underemployment, low average wages, inflation, and a lack of career opportunities in local industries.

(c) Large-scale emigration typically targets young, economically active males and females. This leads to an aging population structure in the source country and a reduction in the birth rate as young families migrate. Economically, it depletes the domestic workforce (especially skilled professionals, known as 'brain drain'), but the domestic economy benefits from financial remittances sent back by overseas workers to their families.

Marking scheme

Part (a) [2 marks]:
- 1 mark for correct calculation: -50,000 (or loss of 50,000).
- 1 mark for identifying this as a net migration loss.

Part (b) [2 marks]:
- 1 mark for each economic push factor identified, up to 2 marks (e.g., high unemployment, low salaries, poverty, lack of jobs, poor working conditions). Reject environmental or political factors unless directly tied to economic survival.

Part (c) [4 marks]:
- Up to 2 marks for effects on population structure (e.g., loss of reproductive/working-age group, aging population, increased proportion of elderly/children, gender imbalance if migration is male-dominated).
- Up to 2 marks for effects on economy (e.g., brain drain/loss of skilled labor, decline in productivity, but positive impact of financial remittances, reduction of pressure on job markets).
Question 6 · Thematic Skill Application

Study the employment structure data for three countries in the table below:

- Country A: Primary 5%, Secondary 25%, Tertiary 70%
- Country B: Primary 65%, Secondary 15%, Tertiary 20%
- Country C: Primary 15%, Secondary 45%, Tertiary 40%

(a) Identify which country is most likely to be an LEDC (Less Economically Developed Country) and justify your answer using the data. [2]

(b) Explain why high-technology industries are considered 'footloose' and state three factors that influence their specific location. [3]

(c) Explain the difference between primary and secondary economic activities. [3]
Show answer & marking scheme

Worked solution

(a) Country B is the LEDC. In the early stages of development (Clark-Fisher model), the primary sector dominates because subsistence agriculture is the primary means of survival, and there is a lack of advanced machinery and service industries.

(b) High-technology industries produce lightweight, high-value components (like microchips). They do not require bulky materials like coal or iron ore, making transport costs of inputs low. Thus, they are 'footloose' and locate where they can access highly educated labor pools, specialized business parks, and fast transport links (e.g., motorways and airports).

(c) Primary economic activities yield raw, unprocessed natural resources directly from the biosphere, lithosphere, or hydrosphere. Secondary economic activities transform these primary products into tangible, consumer-ready goods through refining, processing, and assembly lines.

Marking scheme

Part (a) [2 marks]:
- 1 mark for identifying Country B.
- 1 mark for data-backed justification (e.g., high primary employment of 65% / low tertiary employment of 20%, representing dependency on agriculture).

Part (b) [3 marks]:
- 1 mark for explaining 'footloose' (i.e., not tied to raw material sites because raw materials are not heavy/bulky / transport of finished products is easy/cheap).
- 2 marks for identifying location factors (e.g., proximity to universities for research/skilled staff, pleasant environmental living conditions, modern high-speed communication infrastructure, transport links like airports/highways). Max 3 marks.

Part (c) [3 marks]:
- 1 mark for definition/explanation of primary activities (extraction of natural resources/raw materials).
- 1 mark for definition/explanation of secondary activities (processing raw materials/manufacturing goods).
- 1 mark for providing accurate examples of each (e.g., farming/mining for primary; car assembly/food packaging for secondary).

Students from a school in Devon, UK, investigated the impact of coastal management structures on beach morphology at a local resort. They focused their investigation on a series of wooden groynes built along the beach. They wanted to test the following hypotheses: Hypothesis 1: The beach is wider and has a steeper profile on the updrift side of a groyne than on the downdrift side. Hypothesis 2: Average pebble size decreases with distance from the high-water mark (HWM) towards the low-water mark (LWM).

(4 marks) (a)(ii) Identify two safety precautions the students should take when conducting fieldwork on this beach. (2 marks) (b) The students measured the beach width at five different groynes. They measured from the groyne to the edge of the dry beach on both the updrift and downdrift sides. Their results are shown in Table 1: Groyne 1 (Updrift: 15.2m, Downdrift: 5.8m), Groyne 2 (Updrift: 16.0m, Downdrift: 6.1m), Groyne 3 (Updrift: 14.5m, Downdrift: 6.2m), Groyne 4 (Updrift: 17.1m, Downdrift: 5.9m), Groyne 5 (Updrift: 15.8m, Downdrift: 6.0m).

(c)(i) Explain how they could select the pebbles at each interval to ensure a systematic, unbiased sample. (3 marks) (c)(ii) Describe how they would measure the size of each selected pebble. (3 marks) (c)(iii) At the HWM (0m), the average pebble size was 5.4 cm. At 3m, it was 4.2 cm. At 6m, it was 3.1 cm. At 9m, it was 2.2 cm. At the LWM (12m), it was 1.1 cm. State whether these results support Hypothesis 2. Justify your answer using the data provided. (4 marks) (d) Explain how a groyne causes the difference in beach width and profile between its updrift and downdrift sides. (4 marks) (e) Suggest how the students could improve the reliability and accuracy of their data if they repeated this investigation. (4 marks)
Show answer & marking scheme

Worked solution

Step-by-step Solution: Part (a)(i) requires a clear fieldwork methodology for measuring beach profiles. Ranging poles are placed at breaks of slope, distances measured with a tape, and angles read with a clinometer between matching height markers. Part (a)(ii) demands practical safety actions like checking local tide timetables and wearing high-grip shoes. Part (b)(i) outlines comparative bar chart construction. Part (b)(ii) requires analyzing the data table: comparing updrift (averaging over 15m) to downdrift (averaging around 6m), which clearly proves the hypothesis. Part (c)(i) and (ii) focus on pebble sampling without bias (using quadrats with systematic point-sampling) and measurement technique (using calipers along the long axis). Part (c)(iii) uses the provided pebble size data (5.4 cm down to 1.1 cm) to validate the second hypothesis. Part (d) applies geographical theory of longshore drift blockage.
