(c) Suggest one method to make data collection more reliable. [1 mark]

Sample answers:

• Repeat the survey multiple times
• Use multiple survey locations
• Standardize the survey area size
• Survey at different times/days
• Use multiple surveyors for comparison

Question 4 [8 marks]

(a) Name the coastal landform shown. [1 mark]

Answer: Headland/Rocky headland/Cliff

(b) Describe three features visible in the photograph. [3 marks]

Sample answers (any 3):

• Steep rocky cliffs
• Sea caves at the base of cliffs
• Natural arches formed in the rock
• Offshore stacks/rock pillars
• Wave-cut platforms
• Layered rock structure/bedding planes

Marking: 1 mark per accurate feature description

(c) Explain how wave erosion has created these features. [4 marks]

Sample answer: Hydraulic action occurs when waves crash against the cliff, compressing air in cracks and creating pressure when waves retreat. Abrasion happens as waves hurl rocks and sand against the cliff face. These processes exploit weaknesses like joints and bedding planes in the rock. Over time, caves are enlarged and may break through to form arches. When arches collapse, isolated stacks remain offshore.

Marking scheme:

• 1 mark for hydraulic action explanation
• 1 mark for abrasion explanation
• 1 mark for mentioning rock weaknesses (joints/bedding planes)
• 1 mark for sequence of landform development (caves→arches→stacks)

Section B: Map Skills [15 marks]

Question 5 [6 marks]

(a) Identify two threats from urban development. [2 marks]

Sample answers:

• Road construction fragments habitats
• Urban expansion reduces reserve size
• Pollution from traffic and buildings
• Noise pollution disturbs wildlife
• Light pollution affects nocturnal species
• Increased human access and disturbance

Marking: 1 mark per valid threat identified from map evidence

(b) Explain how MacRitchie Reservoir location helps water security. [2 marks]

Sample answer: Located in forested catchment area which provides clean water supply. Central location allows efficient distribution across Singapore. Protected by nature reserve status preventing contamination from development.

Marking: 1 mark for catchment function, 1 mark for strategic location/protection

(c) Suggest why MRT lines avoid nature reserves. [2 marks]

Sample answer: Construction would damage sensitive ecosystems and wildlife habitats. Government policy protects nature reserves from development. Alternative routes around reserves minimize environmental impact while still providing transport access.

Marking: 1 mark for environmental protection, 1 mark for policy/planning consideration

Question 6 [9 marks]

(a) Describe relationship between earthquakes and plate boundaries. [2 marks]

Answer: Most earthquakes occur along or near plate boundaries. Earthquake frequency and magnitude appear higher near active plate boundaries, particularly where oceanic and continental plates meet.

Marking: 1 mark for spatial relationship, 1 mark for noting concentration along boundaries

(b) Explain why Indonesia has more earthquakes than Malaysia. [3 marks]

Sample answer: Indonesia is located directly on active plate boundaries where Indo-Australian, Eurasian, and Pacific plates meet. Malaysia is located further from major plate boundaries on the relatively stable Eurasian plate. Indonesia sits on the "Ring of Fire" with high tectonic activity, while Malaysia experiences fewer and weaker earthquakes due to its more stable geological position.

Marking: 1 mark each for Indonesia's location on plate boundaries, Malaysia's stable position, and reference to tectonic activity levels

(c) Predict impacts of magnitude 7.5 earthquake near Jakarta. [4 marks]

Predicted impacts:

• Building collapse, especially older/poorly constructed structures
• Casualties from falling debris and building collapse
• Infrastructure damage (roads, bridges, utilities)
• Economic disruption and business closure
• Secondary hazards like fires and landslides

Reasoning: Jakarta has high population density and many buildings not designed for major earthquakes. Soft sediments in coastal areas may amplify shaking. Limited earthquake preparedness compared to countries like Japan.

Marking: 2 marks for realistic impact predictions, 2 marks for sound reasoning based on Jakarta's characteristics

Section C: Fieldwork Application [15 marks]

Question 7 [8 marks]

(a) Suitable research question. [1 mark]

• "To what extent has tourism damaged the natural environment of Sentosa?"

Marking: 1 mark for clear, focused research question about tourism-environment relationship

(b) Suitable sampling method. [2 marks]

Sample answer: Use systematic sampling along transects from beach areas to inland areas at regular intervals (e.g., every 100m). This ensures representative coverage of different zones with varying tourism intensity.

Marking: 1 mark for systematic/stratified sampling, 1 mark for spatial justification

(c) Two types of primary data and usefulness. [4 marks]

Sample answers:

Data type 1: Environmental quality surveys (noise levels, litter count, vegetation damage) Why useful: Provides quantitative measures of environmental degradation that can be compared between high and low tourism areas.

Data type 2: Tourist behavior observations/questionnaires
Why useful: Identifies specific activities causing environmental impact and tourist awareness of environmental issues.

Marking: 1 mark per data type, 1 mark per explanation (4 total)

(d) One limitation of fieldwork method. [1 mark]

Sample answers:

• Time-consuming to cover large area
• Weather conditions may affect data collection
