Section C: Coastal Environments and Data Analysis [15 marks]

Question 17 [3 marks] Describe the distribution of mangroves in Singapore.

Sample Answer: Mangroves are found along the northern and western coastlines of mainland Singapore. They are also present on offshore islands such as Pulau Ubin and Pulau Tekong. The largest mangrove area is at Sungei Buloh in the northwest.

Marking:

• 1 mark: Coastal/shoreline distribution
• 1 mark: Specific locations/directions
• 1 mark: Reference to offshore islands

Question 18 [3 marks] Explain why mangrove forests are found in sheltered coastal environments.

Sample Answer: Mangrove seedlings need calm water conditions to establish and take root without being uprooted by strong waves or currents. Sheltered environments provide protection from strong winds and wave action, allowing young mangroves to grow successfully. The calm conditions also allow sediment to settle, creating suitable muddy substrates for mangrove growth.

Marking:

• 1 mark: Reference to seedling establishment needs
• 1 mark: Protection from waves/currents
• 1 mark: Sediment deposition/substrate formation

Question 19 [4 marks] Describe how mangroves help prevent coastal erosion.

Sample Answer: Mangroves have dense root systems that trap and stabilize loose sediments along the coast. The trapped sediments accumulate over time, building up the coastal area. The root networks also reduce wave energy and slow down water flow, preventing the washing away of coastal materials. The aerial roots act as natural barriers that break up wave action before it reaches the shore.

Marking:

• 1 mark: Root systems trap sediments
• 1 mark: Sediment accumulation/coastal building
• 1 mark: Reduction of wave energy
• 1 mark: Physical barrier effect

Question 20 [5 marks] Analyze temperature data and suggest reasons for differences.

Analysis: Site Q (East Coast Park) shows higher temperatures than Site P (Sungei Buloh) at both morning and afternoon readings. The temperature difference is greater in the afternoon (4°C difference) compared to morning (2°C difference).

Reasons for differences:

• Vegetation cover: Sungei Buloh has dense mangrove canopy that provides shade and cooling, while East Coast Park has less tree cover
• Urban heat island effect: East Coast Park is closer to urban development which generates and retains more heat
• Coastal exposure: East Coast Park may be more exposed to direct sunlight and heat absorption from concrete surfaces

Marking:

• 2 marks: Analysis of data patterns with specific figures
• 3 marks: Three reasons with explanations (1 mark each)
