PRELIMINARY EXAMINATION - ANSWER KEY & MARKING SCHEME

Version 4 of 5

---

Section A: Map, Graph & Data Skills (20 marks)

1. Coastal Landform Interpretation (a) Identify the coastal landform shown in Figure 1. [1]

• Answer: A stack / sea stack.

(b) Describe two features of this landform that are visible in the photograph. [2]

• Award 1 mark for each valid feature described with reference to the photo.
• Possible features:
  • It is a steep-sided, isolated pillar of rock standing in the sea, detached from the mainland/cliffs.
  • The rock shows clear vertical jointing or bedding planes.
  • There is evidence of undercutting at the base (a wave-cut notch).
  • The surrounding water appears shallow with visible rock debris at the base.

(c) With reference to the photograph, explain how this landform was formed. [3]

• Award 1 mark for each step in the formation process, with clear links to the photograph.
• Answer method:
  • Step 1 (1m): The stack was originally part of a headland. Lines of weakness (joints/faults) visible in the rock were attacked by hydraulic action and abrasion, forming a cave.
  • Step 2 (1m): Continued erosion on both sides of the headland caused the cave to extend through to form an arch. The photograph shows the isolated nature of the stack, indicating the arch's roof has since collapsed.
  • Step 3 (1m): The roof of the arch collapsed due to gravity and lack of support, leaving the isolated pillar (the stack) separated from the retreating cliff line.

2. Pie Chart Construction (a) Calculate the total number of visitors to the nature reserve. [1]

• Answer: 450 + 300 + 150 + 70 + 30 = 1000 visitors

(b) Calculate the percentage of visitors from Singapore. Show your working. [2]

• Award 1 mark for correct working, 1 mark for correct answer.
• Working: (450 / 1000) × 100%
• Answer: 45%

(c) Construct a pie chart to represent the data in Table 1. [3]

• Award 1 mark for each of the following:
  • Correct angle calculations (implicit): Singapore (162°), Other Asian (108°), Europe (54°), Americas (25.2°), Others (10.8°). Tolerance of ±2°.
  • Accurate plotting: Sectors are correctly sized and labeled or a clear legend is provided.
  • Presentation: Chart has an appropriate title (e.g., "Origin of Visitors to Bukit Timah Nature Reserve").

3. Climograph Interpretation (a) State the mean annual temperature and the total annual rainfall. [2]

• Award 1 mark for each correct reading.
• Answer: (Values will depend on the specific climograph in Figure 3. Example:)
  • Mean annual temperature: 27°C
  • Total annual rainfall: 2400 mm

(b) Name the climate type shown in Figure 3. [1]

• Answer: Tropical Equatorial Climate / Tropical Rainforest Climate.

(c) Account for the high rainfall experienced by this location throughout the year. [3]

• Award 1 mark for each valid point of explanation.
• Answer method:
  • High insolation (1m): The location is near the equator, receiving high solar radiation throughout the year. This causes intense heating of the ground and air.
  • Convectional rainfall (1m): The heated air rises rapidly in strong convection currents, cools, and condenses to form cumulonimbus clouds, leading to heavy, daily convectional rain.
  • ITCZ influence (1m): The location is under the influence of the Inter-Tropical Convergence Zone (ITCZ) for most of the year, where converging trade winds force air to rise, leading to high rainfall.

4. Map Analysis – Protected Area Management With reference to Figure 4, explain how the creation of this marine park helps to conserve the quality of the coastal ecosystem. [4]

• Award 1 mark for each identified map feature and 1 mark for a linked explanation of its conservation role. Two features with explanations are required.
• Possible features and explanations:
  • No-take zones / Core conservation zones (1m): These areas on the map prohibit all fishing and extraction. This allows fish stocks and coral reefs to recover and thrive, acting as a nursery for the wider ecosystem (1m).
  • Mooring buoys (1m): The map shows designated mooring points for boats. This prevents anchors from being dropped onto and destroying fragile coral reefs (1m).
  • Visitor education centre (1m): The presence of a centre on the map indicates a focus on educating tourists about the ecosystem's fragility, promoting responsible behaviour like not touching corals or littering (1m).
  • Zoned areas for recreation (1m): By restricting activities like snorkeling and diving to specific, resilient zones, the park limits human pressure on the most sensitive habitats (1m).

Section B: Structured Response (15 marks)

5. Explain how the geology of a coastal area can affect the rate of erosion. [6]

• Award marks for explaining the role of rock type and rock structure.
• Rock Type (up to 3 marks):
  • Resistance (1m): Different rock types have different resistance to erosion. For example, granite is highly resistant due to its interlocking crystals and slow weathering rate.
  • Chemical composition (1m): Rocks like limestone are susceptible to solution/carbonation, where weak acids in seawater dissolve the rock, accelerating erosion.
  • Permeability (1m): Permeable rocks absorb water, reducing surface runoff but can be weakened by chemical weathering. Impermeable rocks promote surface runoff, which can erode the cliff face.
• Rock Structure (up to 3 marks):
  • Joints and faults (1m): Closely spaced joints and faults are lines of weakness. They are exploited by hydraulic action and abrasion, making erosion much faster than in solid, unjointed rock.
  • Bedding planes (1m): The angle of bedding planes matters. Horizontal bedding planes can create resistant platforms, while seaward-dipping planes create unstable cliffs prone to landslides.
  • Dip of strata (1m): Rocks dipping towards the sea are more vulnerable to mass wasting and wave erosion than rocks dipping inland.

6. Describe the formation of a beach, and explain how beach material can affect the slope of the beach. [6]

• Formation of a beach (up to 3 marks):
  • Sediment source (1m): Beaches form from sediment (sand, shingle) deposited by rivers, eroded from cliffs, or transported from offshore by waves.
  • Transport (1m): Waves and longshore drift transport this sediment along the coast.
  • Deposition (1m): Deposition occurs in low-energy environments, such as sheltered bays, where wave energy is reduced. The sediment accumulates between the low-water mark and the storm beach line.
• Effect of beach material on slope (up to 3 marks):
  • Permeability and particle size (1m): Coarse, permeable material like shingle/pebbles allows a strong swash to percolate quickly. This creates a weak backwash that cannot drag material back down, resulting in a steep beach slope.
  • Compaction and friction (1m): Fine, impermeable material like sand causes a weak swash to drain slowly. The resulting strong backwash pulls sand particles seaward, creating a wide, gently sloping beach profile.
  • Gravity (1m): Larger, heavier material can rest at a steeper angle of repose than fine sand, which is easily flattened by the backwash.

7. With reference to Figure 5, explain how the fragile nature of the coastline poses challenges for humans. [3]

• Award 1 mark for each challenge clearly linked to the fragility shown in the figure.
• Answer method:
  • Identify fragility (1m): The figure shows a low-lying coastal settlement with a narrow sand beach and no significant sea defenses, making it fragile to erosion and flooding.
  • Challenge 1: Property loss (1m): Coastal erosion can undermine buildings and infrastructure, leading to the loss of homes and roads, as the coastline retreats.
  • Challenge 2: Flooding (1m): The low elevation makes the settlement highly vulnerable to inundation during storm surges or high tides, threatening lives and property.

Section C: Essay (15 marks)

8. "Since earthquakes are hard to predict, it is better to invest in response measures than preparedness measures." To what extent do you consider this statement to be true? Use examples. [15]

Marking Descriptors:

Level	Marks	Descriptor
L4	13-15	A comprehensive and well-balanced evaluation. The answer clearly distinguishes between preparedness and response, arguing for their interdependence. Detailed, place-specific examples are used effectively to support a nuanced conclusion.
L3	9-12	A good evaluation with a clear argument. The answer explains both sides of the statement but may lack depth in one area. Examples are relevant but may lack detail. A clear conclusion is present.
L2	5-8	A basic argument that is mostly descriptive or one-sided. The answer shows knowledge of some measures but does not evaluate their relative importance effectively. Examples are generic or poorly linked.
L1	1-4	A weak answer with little or no evaluation. Statements are general, unsupported, and may contain errors. No clear conclusion.

Indicative Content:

• Introduction: Define preparedness (land-use planning, building codes, education, drills) and response (search and rescue, emergency aid, evacuation). Acknowledge the difficulty of prediction.
• Arguments for the statement (Response is better):
  • Since timing is unknown, resources are wasted if preparedness is for an event that doesn't occur soon.
  • Effective response directly saves lives immediately after an event (e.g., rapid search and rescue teams in Japan 2011).
  • Response measures like early warning systems (e.g., Pacific Tsunami Warning Center) can provide minutes to hours of notice, which is more directly useful than long-term building codes.
• Arguments against the statement (Preparedness is critical):
  • Preparedness reduces vulnerability, which is a key factor in the disaster risk equation. Response cannot save people if buildings collapse instantly (e.g., Haiti 2010 earthquake, where poor building codes caused mass casualties).
  • Strict building codes in Japan and California save countless lives by preventing infrastructure collapse, proving that long-term investment is effective.
  • Education and drills (e.g., in Japanese schools) ensure people know how to react, reducing panic and injury, a form of preparedness that is always valuable.
• Conclusion: A balanced view is required. While response is vital for immediate life-saving, preparedness is the only way to reduce the scale of the disaster in the first place. Both are essential and complementary, but in highly vulnerable regions, investment in preparedness yields the greatest long-term reduction in risk.

9. 'Recent climate change is more affected by natural causes than anthropogenic factors.' To what extent do you consider this statement to be true? Give reasons to support your answer. [15]

Marking Descriptors: (Same levels as Q8)

Indicative Content:

• Introduction: Define natural causes (solar variation, volcanic activity, orbital cycles) and anthropogenic factors (burning fossil fuels, deforestation, industrial processes).
• Arguments for the statement (Natural causes are dominant):
  • Earth's climate has changed naturally throughout history (e.g., glacial and interglacial periods) due to Milankovitch cycles.
  • Solar output variations and major volcanic eruptions (e.g., Mount Pinatubo 1991) have a measurable cooling effect, showing nature's power to alter climate.
• Arguments against the statement (Anthropogenic factors are dominant):
  • The rate of warming since the Industrial Revolution is unprecedented and correlates directly with the sharp rise in greenhouse gas (GHG) emissions from human activities.
  • The physical science of the greenhouse effect is well-established; increased CO₂ and methane from human activity trap more heat.
  • Scientific consensus (IPCC) attributes the majority of recent warming to human activity. Isotopic analysis of carbon in the atmosphere proves the added CO₂ comes from fossil fuels.
  • Natural factors like solar activity have not increased significantly in the last 50 years, meaning they cannot explain the observed rapid warming.
• Conclusion: While natural factors drive long-term climate cycles, the overwhelming scientific evidence shows that the recent, rapid climate change is predominantly caused by anthropogenic factors. The statement is largely false.
