2023 Cambridge IGCSE Geography (0460) 模擬試題連答案詳解

(a) (i) The sphere of influence is the area served by a settlement, shop, or service.
(ii) Factors include:
- The population size of the settlement.
- The range and order of goods/services provided.
- The quality of accessibility/transport links.
- The degree of competition from other neighboring settlements.
(iii) Frequency of use: Services used daily (e.g., bakeries) need a small threshold population because people purchase products constantly. Services used rarely (e.g., furniture shops) need a much larger threshold population to ensure enough customers over a given period.
Cost: Expensive services require a higher threshold population to make a profit because fewer transactions occur, whereas cheap goods can rely on small populations.
(iv) Low-order services (e.g., newsagents, grocery stores) offer convenience goods that are cheap, bought frequently, and have a short range/threshold, meaning they can survive in small villages as well as large cities. High-order services (e.g., luxury car dealerships, specialist hospitals) provide comparison goods that are expensive, bought rarely, and have a huge threshold population and range, which is only supported by the massive, diverse population of a major city.

(b) (i) In the zone of transition (inner city), housing is older (often Victorian/industrial), higher density (terraced housing, high-rise flats), and lacks private open green spaces. In contrast, the suburbs feature modern, lower-density housing (detached/semi-detached houses), large private gardens, and tree-lined streets with nearby parks.
(ii) Challenges in rapidly growing LEDC cities include:
- Formation of squatter settlements/slums with poorly built, hazardous housing.
- Lack of clean piped water, proper sewage systems, and sanitation, causing water-borne diseases.
- High rates of unemployment or underemployment, pushing people into dangerous or poorly paid informal jobs.
- Severe traffic congestion and air/water pollution due to overburdened municipal infrastructure.
- Overcrowded schools, hospitals, and high crime rates due to inadequate municipal policing and funding.

(c) Case Study: London, UK (Traffic Congestion)
- Strategy 1: Congestion Charge. Introduced in central London, charging vehicles driving into the central zone. This directly reduced private vehicle volume and encouraged public transport usage.
- Strategy 2: Cycle Superhighways and Santander Cycles. Dedicated cycle lanes protected from traffic lanes were created, along with public bike-sharing schemes, facilitating zero-emission commuting.
- Strategy 3: Investment in Public Transport. Projects like Crossrail (the Elizabeth Line) and expansions of the London Underground have increased passenger capacity, reducing reliance on private cars.

(a) (i) 1 mark for clear definition:
- Area served by a settlement / shop / service.

(ii) 1 mark per valid factor (max 2):
- Population size of the settlement.
- Range / order of goods and services.
- Level of transport links / accessibility.
- Level of competition from nearby settlements.

(iii) 3 marks total:
- 1 mark for linking high frequency of use to a low threshold population (or vice versa).
- 1 mark for linking high cost to a high threshold population (or vice versa).
- 1 mark for clear reasoning / exemplification.

(iv) 4 marks total:
- 1 mark for identifying low-order services as having small range/threshold/convenience.
- 1 mark for explaining why villages can support low-order services.
- 1 mark for identifying high-order services as having large range/threshold/comparison.
- 1 mark for explaining why only cities can support high-order services.

(b) (i) 3 marks total (must compare/contrast both zones to get full marks):
- Max 2 marks if only describing one zone.
- Points: high density vs low density; terraced/flats vs detached/semi-detached; lack of green space vs private gardens; older vs modern housing.

(ii) 5 marks total (1 mark per distinct challenge explained):
- Squatter settlements / poor building structures [1]
- Inadequate sanitation / lack of clean water [1]
- High unemployment / growth of informal sector [1]
- Traffic congestion / air pollution [1]
- High crime / strain on services (schools/hospitals) [1]

(c) 7 marks total (Case Study):
- Level 1 (1-3 marks): Simple, generic statements describing a problem or strategy without specific local detail.
- Level 2 (4-6 marks): Explains specific strategies for a named urban area, explaining *how* they work.
- Level 3 (7 marks): Detailed, comprehensive explanation with specific names of strategies and place-specific details for the chosen city.

(a) (i) Barometer (or Aneroid Barometer).
(ii) Read the maximum temperature at the base of the index on the maximum side. Read the minimum temperature at the base of the index on the minimum side. Subtract the minimum temperature from the maximum temperature to find the diurnal temperature range.
(iii) Read the air temperature on the dry-bulb thermometer. Read the temperature on the wet-bulb thermometer (which is cooled by evaporation). Subtract the wet-bulb temperature from the dry-bulb temperature to find the wet-bulb depression. Use a relative humidity conversion table to find where the dry-bulb value and wet-bulb depression intersect.
(iv) It must be placed in an open area, away from tall trees and buildings (to avoid shade and artificial wind blockages). It should be sited over grass (not concrete/tarmac, which absorb and radiate heat). It must be elevated 1.25 meters above the ground (to prevent ground radiation from affecting the air temperature readings). It must be painted white (to reflect direct sunlight).

(b) (i) Features: Fluffy, cotton-wool appearance, white at the top with a dark, flat base. Formation: Convection currents occur when the sun heats the ground, heating the air above it. The warm air rises, cools at the dry adiabatic lapse rate, reaches dew point, and condenses into cloud droplets.
(ii) High temperatures: High solar angle means concentrated insolation; clear skies allow maximum incoming solar radiation to reach the desert surface without cloud reflection. Low rainfall: Located at 20° to 30° north and south of the equator, in the subtropical high-pressure belt where air is descending, warming, and drying, preventing condensation. Prevailing trade winds are blowing from land to sea (offshore) and contain little moisture.

(c) Case Study: Cyclone Nargis in Myanmar (2008)
- Impact 1: Severe flooding of the Irrawaddy Delta caused by a 3.5-meter storm surge, which swept away coastal villages and drowned livestock.
- Impact 2: Over 138,000 deaths and widespread destruction of infrastructure, including hospitals, roads, and communication lines, which delayed emergency aid.
- Impact 3: Loss of agricultural land. The storm surge salinized fertile rice paddies, destroying crops and causing long-term food insecurity and economic hardship for local farmers.

(a) (i) 1 mark for Barometer / Aneroid Barometer.

(ii) 2 marks:
- 1 mark for identifying that the maximum and minimum readings are taken from the bottom of the metal indexes.
- 1 mark for explaining that the minimum temperature is subtracted from the maximum temperature.

(iii) 3 marks:
- 1 mark for recording dry-bulb and wet-bulb temperatures.
- 1 mark for calculating the wet-bulb depression (difference between the two).
- 1 mark for using relative humidity tables / chart.

(iv) 4 marks (1 mark per site condition explained, max 4):
- Sited on grass / natural surface (avoids concrete radiation) [1]
- Open space / away from buildings/trees (prevents shading/sheltering) [1]
- Standard height / 1.25-1.5m above ground (avoids ground heat transfer) [1]
- Painted white (reflects solar radiation) [1]
- Louvered / slatted sides (allows free flow of air) [1]

(b) (i) 3 marks:

(c) 7 marks total (Case Study):
- Level 1 (1-3 marks): General list of impacts of drought/tropical storm (deaths, loss of homes, food shortages).
- Level 2 (4-6 marks): Detailed descriptions of specific primary and secondary impacts in a named location.
- Level 3 (7 marks): Comprehensive, well-explained impacts with specific locational facts and figures for the named area.

(a) (i) The movement of water up the beach after a wave breaks.
(ii) Differences:
- Constructive waves have a stronger swash than backwash, whereas destructive waves have a stronger backwash than swash.
- Constructive waves have a lower wave height and frequency, whereas destructive waves have a higher wave height and frequency.
(iii) Hydraulic action: Waves crash against the cliff, trapping air in cracks. The air is compressed, and as the wave retreats, the pressure is suddenly released, causing the rock to shatter.
Abrasion: Waves fling rocks, sand, and pebbles against the base of the cliff, chipping away and wearing down the rock surface like sandpaper.
(iv) Waves approach the shore at an oblique angle, driven by the prevailing wind. The swash carries sediment up the beach at this same angle. The backwash then drags sediment straight back down the beach at a right angle (90 degrees) due to gravity. This continuous zig-zag movement transports material along the coast.

(b) (i) Longshore drift moves sediment along the coast. Where there is a change in the shape of the coastline (e.g., at an estuary or headland), the sediment is deposited in the sheltered, shallow water. Over time, deposition builds up a ridge of sand and shingle that projects out into the sea. Winds or secondary waves may curve the end of the spit, forming a hook.
(ii) Formation: Coral reefs are built by millions of tiny polyps that extract calcium carbonate from seawater to build protective skeletons. When they die, new polyps grow on top of the old skeletons, building up the reef.
Conditions required:
- Warm sea temperatures between 18°C and 30°C.
- Shallow water (less than 60m) so sunlight can reach zooxanthellae (algae) for photosynthesis.
- Clean, clear, sediment-free water to prevent smothering.
- Saline, well-oxygenated water with strong waves to bring nutrients.

(c) Case Study: Holderness Coast, Yorkshire, UK
- Opportunities: Tourism in seaside resorts like Hornsea and Bridlington, where sand beaches support local shops and guest houses. Gas terminals at Easington process a significant proportion of the UK's North Sea gas, providing energy and employment.
- Hazards: Severe coastal erosion (soft boulder clay cliffs erode at up to 2 meters per year). This has caused homes to fall into the sea at villages like Skipsea, dropping property values and causing psychological distress to residents. Coastal roads are also destroyed, isolating communities.

(a) (i) 1 mark for defining swash (movement of water up the beach).

(ii) 2 marks for stating two differences (1 mark per distinct comparative point):
- Constructive waves have strong swash/weak backwash, destructive have weak swash/strong backwash.
- Constructive waves are low/gentle, destructive waves are high/steep.
- Constructive waves deposit, destructive waves erode.
- Constructive waves have low frequency, destructive waves have high frequency.

(iii) 3 marks:
- 1.5 marks for explaining hydraulic action (trapped air, compression, sudden release/shattering).
- 1.5 marks for explaining abrasion (waves throwing sediment/rocks against the cliff base).

(iv) 4 marks:
- Prevailing wind blows waves at an angle to the coast [1]
- Swash carries material up the beach at an angle [1]
- Backwash carries material straight down due to gravity [1]
- Repetition of this process leads to a zig-zag movement along the coast [1]

(b) (i) 3 marks:
- Longshore drift carries sediment past a change in coast shape / river mouth [1]
- Sediment is deposited in the slack, shallow water [1]
- Ridge grows outward and curves at the end due to change in wind direction / currents [1]

(ii) 5 marks (max 2 on polyp formation, max 4 on environmental conditions):
- Polyps build calcium carbonate skeletons [1]
- Warm water temperatures (18°C to 30°C) [1]
- Shallow water / less than 60m depth (sunlight) [1]
- Clear, sediment-free water [1]
- Saline water / high oxygen levels [1]

(c) 7 marks total (Case Study):
- Level 1 (1-3 marks): Simple description of opportunities and hazards in general coastal areas.

- Level 3 (7 marks): Detailed, balanced case study with specific locational details and clear explanations of both opportunities and hazards.

(a) (i) The point on the Earth's surface directly above the focus of an earthquake.
(ii) The focus is the exact point underground where the earthquake originates (the fracture point along the fault line). The epicentre is the point on the ground surface directly above it, where the strongest seismic shockwaves are first felt.
(iii) Convection currents in the mantle pull two plates toward each other. The denser, heavier oceanic plate is forced downward beneath the lighter continental plate in a process called subduction, moving into the asthenosphere where it melts due to intense friction and heat.
(iv) At conservative boundaries, two plates slide horizontally past one another, either in opposite directions or in the same direction at different speeds. The edges of the plates are rough and jagged, causing them to catch and become locked together by friction. As plates continue to try to move, tension and pressure build up in the rocks. Eventually, the strain exceeds the strength of the rock, causing it to suddenly fracture and slip, releasing accumulated potential energy as seismic waves.

(b) (i) Hazards:
- Pyroclastic flows: Superheated, fast-moving clouds of toxic gases, ash, and rock fragments that incinerate everything in their path.
- Ash fall: Fine volcanic ash that covers landscapes, collapses building roofs, ruins crops, and disrupts aviation.
- Lahars: Mudflows formed when volcanic ash mixes with melted snow/glaciers or heavy rain, rushing down river valleys.
(ii) Reduction through:
- Preparation: Regular earthquake drills in schools and offices to educate the public; disaster response kits; mapping high-risk seismic zones to avoid building there; installing early-warning warning sirens.
- Engineering: Constructing earthquake-resistant buildings using shock absorbers/base isolators at the foundations, cross-bracing steel frames, and using reinforced concrete. Installing flexible utility gas and water pipes to prevent fires and water supply failures.

(c) Case Study: Tohoku Earthquake, Japan (2011)
- Causes: Occoured at a convergent (destructive) plate boundary. The Pacific Plate subducted beneath the Eurasian Plate (North American subplate). Friction caused the plates to lock, building up massive elastic tension. On March 11, the plate ruptured, releasing a magnitude 9.0 earthquake and displacing a huge volume of water above the fault line.
- Effects: The earthquake caused building collapse and fires, but the resulting tsunami caused the vast majority of deaths (nearly 16,000 people drowned). The tsunami flooded the Fukushima Daiichi nuclear power plant, causing a cooling system failure, nuclear meltdowns, and radiation leaks, forcing over 150,000 people to evacuate their homes.

(a) (i) Mass tourism is tourism on a large scale, involving huge numbers of people visiting the same resort or destination at the same time.
(ii) Reasons:
- Growth in global disposable incomes, allowing more people to afford travel.
- Growth of budget airlines and cheaper flights, making air travel accessible.
- More paid annual leave and shorter working weeks.
- Easier booking systems via the internet and online travel agencies.
(iii) Benefits:
- Creates direct employment in hotels, restaurants, and as tour guides.
- Indirect employment through construction and local agricultural suppliers (multiplier effect).
- Tourism generates foreign exchange currency for the country.
- Tax revenues from tourism allow the government to improve infrastructure (roads, clean water, hospitals).
(iv) Environmental impacts:
- Clearance of natural habitats (e.g., clearing mangroves or forests) to build hotels.
- Water pollution from untreated sewage discharged into the sea, damaging coral reefs.
- High carbon emissions and air pollution from aircraft and tourist vehicles.
- Depletion of local groundwater reserves due to high consumption by hotels (golf courses, laundry, pools).

(b) (i) The Butler Model shows the evolution of a resort through stages:
- Exploration & Involvement: Very few tourists visit; basic local amenities are developed.
- Development & Consolidation: Mass tourism occurs with foreign investment, major hotel construction, and tourism becomes the dominant economic sector.
- Stagnation: Carrying capacity is reached; the resort becomes crowded, run-down, and starts losing its appeal.
- Decline or Rejuvenation: The resort either loses tourists to competitors (decline) or reinvests in new attractions/upgrades to attract visitors again (rejuvenation).
(ii) Sustainable management strategies:
- Enforce daily limits or quotas on tourist numbers (carrying capacity) to prevent overcrowding in fragile areas.
- Promote ecotourism where visitors stay in low-impact eco-lodges made of local renewable materials.
- Use renewable energy sources (solar/wind) and water recycling systems in hotels.
- Ensure a percentage of resort entrance fees goes directly to local wildlife conservation and community development.
- Ban plastic usage on beaches and create marine sanctuaries.

(c) Case Study: Maasai Mara, Kenya
- Development: Developed through safari-based tourism focusing on wildlife viewings (the Big Five) and cultural visits to Maasai villages. Luxury lodges and campsite networks have been built.
- Advantages: Created jobs for the local Maasai people as rangers, drivers, and hotel staff. Income is generated by selling handmade traditional crafts. Some tourism revenue is used to build local schools and health clinics.
- Disadvantages: Land has been taken from the Maasai, restricting their nomadic cattle grazing. Cultural dilution occurs as traditional dances are performed as commercial spectacles. High inflation of local food prices makes basic goods expensive for locals.

(a) (i) Secondary industry is the sector of the economy that processes raw materials into finished or semi-finished goods (manufacturing).
(ii) Inputs include: Raw materials, labor (workers), capital (investment), energy (electricity), and land.
(iii) Weight-losing (bulk-reducing) industries process heavy, bulky raw materials into lighter products (e.g., steel production), so factories locate near raw materials to minimize expensive transport costs.
Weight-gaining (bulk-gaining) industries produce items that are heavier or bulkier than the raw inputs (e.g., soft drink bottling), so they locate close to the market. Perishable products (e.g., bakeries) must also locate near the market to ensure freshness.
(iv) Government policies: Governments can set up enterprise zones with tax holidays, subsidies, and relaxed planning permissions to attract high-tech companies.
Transport networks: High-tech industries depend on rapid, high-quality transport networks like motorways and proximity to international airports to ship valuable, lightweight components quickly and to allow skilled workers to commute easily.

(b) (i) In an LEDC, a high percentage of the workforce is employed in the primary sector (agriculture/mining) due to low mechanization, and the tertiary sector is relatively small. In contrast, an MEDC has a very small primary sector due to high mechanization, a declining secondary sector (due to outsourcing), and a dominant tertiary sector (services, finance, and technology).
(ii) Environmental impacts:
- Air pollution: Factories release greenhouse gases (carbon dioxide) and sulfur dioxide, contributing to global warming and acid rain.
- Water pollution: Chemical effluents and heavy metals dumped into rivers/lakes destroy aquatic ecosystems.
- Solid waste: Toxic sludge and slag heaps take up land space and leak chemicals into the soil.
- Noise/light pollution: Industrial operations disturb local communities and wildlife patterns.
- Resource depletion: Heavy consumption of fossil fuels and raw mineral resources.

(c) Case Study: Toyota Manufacturing Plant, Burnaston, Derby, UK

An exemplary response includes the following details:

(a)(i) The students would calculate a regular sampling interval by dividing the total transect length by the number of desired sites: \( \frac{8\text{ km}}{5} = 1.6\text{ km} \). Starting at the edge of the CBD (0 km), they would identify sites at fixed intervals of 1.6 km (Site 1 at 1.6 km, Site 2 at 3.2 km, Site 3 at 4.8 km, Site 4 at 6.4 km, and Site 5 at 8.0 km) using a map or GPS.

(a)(ii) Safety precautions include: 1) Wearing high-visibility jackets to ensure drivers can see them clearly. 2) Standing safely back on the pavement/footpath, well away from the road edge, during counts.

(b)(i) To ensure reliability: 1) Students should work in pairs or groups of three at each site to discuss and agree on scores, reducing personal bias. 2) They should use a detailed descriptor sheet defining exactly what features constitute a score of -2, 0, or +2. 3) They should conduct assessments at the same time of day and take multiple readings at different spots around each site, calculating an average.

(b)(ii) Advantage: EQI yields quantitative data (numerical scores) which can be easily coded, graphed, and statistically tested.
Disadvantage: The scoring system is highly subjective, and different groups of students might rate the same site differently based on personal standards or transient factors like temporary noise.

(c)(i) To ensure accuracy and comparability: 1) Count traffic at all 5 sites simultaneously (using 5 sub-groups of students). 2) Use mechanical tally counters to prevent miscounting errors. 3) Standardise the classification of vehicles beforehand (e.g., establishing a clear rule on whether to count bicycles or emergency vehicles).

(c)(ii) To construct the bar chart: 1) Label the vertical axis (y-axis) as 'Number of vehicles (per 10 minutes)' with an appropriate scale from 0 to 250. 2) Label the horizontal axis (x-axis) as 'Survey Site (Distance from CBD in km)'. 3) Plot the heights of the bars accurately: Site 1 at 240, Site 2 at 165, Site 3 at 110, Site 4 at 60, and Site 5 at 25. 4) Use uniform bar widths and leave equal gaps between the bars, adding a descriptive title.

(d)(i) Hypothesis 1 is fully supported. The data shows a continuous, direct relationship where environmental quality increases as distance from the CBD increases. At Site 1 (0.5 km from CBD), the EQI is very low at -6, whereas at the furthest point, Site 5 (7.5 km from CBD), the EQI rises to +9, representing an overall increase of \( +9 - (-6) = 15 \) index points over a distance of \( 7.5 - 0.5 = 7.0 \) km.

(d)(ii) Hypothesis 2 is fully supported. Traffic counts decrease consistently from 240 vehicles at Site 1 (0.5 km) to only 25 vehicles at Site 5 (7.5 km), showing a reduction of \( 240 - 25 = 215 \) vehicles. There is also a strong correlation between lower traffic volumes and higher environmental quality; for instance, Site 1 has the heaviest traffic (240 vehicles) and the lowest EQI (-6), while Site 5 has the lightest traffic (25 vehicles) and the highest EQI (+9).

(e) To study the sphere of influence, students could conduct questionnaires with pedestrians in the CBD to ask where they travelled from (recording their residential postcode or town name) and the frequency of their visits. They could then plot these origin points on a base map of the region and draw desire lines or a boundary (using GIS) around the furthest points of origin to delineate the CBD's catchment area.

An exemplary response includes the following details:

(a)(i) The method is as follows: 1) Measure out a fixed distance (e.g., 10 metres) along the beach shoreline parallel to the sea and mark the start and end points with ranging poles. 2) Stand in the water at the start point and place an orange (which acts as a highly visible float that sits low in the water) into the swash zone. 3) Start a stopwatch immediately when the float is released. 4) Stop the stopwatch when the float passes the second ranging pole and record the time in seconds. 5) Observe and record the compass direction of movement (e.g., towards the East). 6) Repeat the procedure 5 times and calculate the average speed of movement using the formula: \( \text{speed} = \frac{\text{distance}}{\text{time}} \).

(a)(ii) Natural factors: 1) Strong onshore or offshore winds can blow the exposed top of the float, causing it to deviate from the true water current. 2) Large waves can wash the float onshore onto the dry beach. To minimise these impacts, students should use a low-profile float like an orange which is almost entirely submerged, and they should perform the experiment on a calm day with typical wave conditions.

(b)(i) To measure a beach profile: 1) Lay out a safety tape measure perpendicular to the shoreline, running from the low-tide line up to the dunes. 2) Identify key 'breaks of slope' along this line. 3) Place one ranging pole at the start and another at the first break of slope. 4) Ensure both ranging poles are held vertically. 5) Use a clinometer to sight from a marked, matching height on the first pole (e.g., eye level, 1.5m) to the same height mark on the second pole, and read the angle of inclination/slope in degrees. 6) Record the distance along the tape between the poles and the angle. 7) Move the poles systematically up the beach to each consecutive break of slope and repeat the steps.

(b)(ii) A beach profile diagram should feature: 1) A continuous, sloped line representing the beach surface from the sea level (left) rising up to the dunes/cliffs (right). 2) Two vertical lines representing the ranging poles placed at different breaks of slope. 3) Annotations showing: a horizontal arrow indicating the 'tape measure measuring distance', a dashed line of sight between the two poles, and a callout showing the 'clinometer at eye level' measuring the angle of inclination in degrees.

(c)(i) To obtain a representative, unbiased sample: 1) Use a quadrat or a belt transect running from the low-water mark to the upper storm beach. 2) Generate random coordinates within the quadrat or select pebbles at fixed intervals along the transect tape (systematic sampling, e.g., every 50 cm). 3) Always pick up the pebble exactly at the intersection point without choosing based on visual appeal (e.g., picking the pebble closest to the toe of your shoe).

(c)(ii) To measure size, students should use callipers to measure the longest axis of each selected pebble in centimetres. To measure roundness, they should visually compare each pebble with a standard Powers' Scale of Roundness chart (showing visual profiles of classes 1 to 6) and assign the matching integer score.

(d)(i) On a scatter graph, pebble size (long axis in cm) would be plotted on the independent horizontal axis (x-axis) from 0 to 10 cm. The average roundness index score (from 1 to 6) would be plotted on the dependent vertical axis (y-axis). Each of the 5 sites would be plotted as a single coordinate point (e.g., Site A at (9.2, 1.8), Site E at (1.2, 5.2)), and a negative line of best fit would be drawn.

(d)(ii) Hypothesis 2 is fully supported by the data from all five sites. As we move from west to east (Site A to Site E): 1) Average pebble size decreases continuously: Site A (9.2 cm) -> Site B (7.1 cm) -> Site C (5.0 cm) -> Site D (3.2 cm) -> Site E (1.2 cm), showing an overall decrease of \( 9.2 - 1.2 = 8.0 \) cm. 2) Average roundness score increases continuously: Site A (1.8 - very angular) -> Site B (2.6) -> Site C (3.5) -> Site D (4.4) -> Site E (5.2 - well-rounded), showing an overall increase of \( 5.2 - 1.8 = 3.4 \) on the index. This matches the transport direction of longshore drift, where pebbles are progressively broken down and smoothed by attrition.

(e) Groynes block the lateral movement of sediment by longshore drift. This causes: 1) Sediment to accumulate on the updrift (western) side, making the beach wider and steeper. 2) Sediment starvation on the downdrift (eastern) side, reducing beach volume and leaving cliffs vulnerable to erosion.

Part (a)(i) [4 marks]:
- 1 mark for measuring a fixed distance (e.g., 10m) using a tape measure and marking with ranging poles.

- 1 mark for recording compass direction and repeating the trial (minimum 3 times) to calculate an average.

Part (a)(ii) [3 marks]:
- 1 mark per valid natural factor (e.g., wind drag, high wave energy pushing float onshore, tidal currents). Max 2.
- 1 mark for a corresponding mitigation strategy (e.g., using a heavy, semi-submerged float like an orange; avoiding days with strong onshore winds; measuring wave frequency and repeating trials).

Part (c)(i) [3 marks]:

Part (c)(ii) [3 marks]:
- 1 mark for using callipers (or a ruler) to measure the long/longest axis of the pebble.
