4. Describe the distribution of mangrove forests shown in Figure 1. [3 marks] Sample Answer:
- Mangroves are found along the coastline/shoreline (1 mark)
- They are located in sheltered areas/bays (1 mark)
- They extend inland along river channels/estuaries (1 mark)
Award 1 mark each for three accurate distributional points
5. Which sampling point has the highest water quality? Use evidence from Figure 2 to support your answer. [2 marks] Answer: Point C (1 mark) Evidence: Point C has the highest dissolved oxygen (7.5 mg/L) and lowest turbidity (8 NTU), indicating cleaner water (1 mark)
Award 1 mark for identifying Point C, 1 mark for using specific data as evidence
6. Explain why Point C might have better water quality than Point B. [3 marks] Sample Answer:
- Point C is further from pollution sources/human activities (1 mark)
- Point C may have better water circulation/flow (1 mark)
- Point C may be in a more sheltered location with less disturbance (1 mark)
Award 1 mark each for three logical explanations
7. Describe one method students could use to measure water temperature during fieldwork. [2 marks] Sample Answer: Use a digital thermometer/temperature probe (1 mark) and place it in the water for 30 seconds to get an accurate reading (1 mark)
Award 1 mark for equipment, 1 mark for method
8. State two safety precautions students should take when conducting water quality testing near mangroves. [2 marks] Sample Answers:
- Wear appropriate footwear/boots to protect feet from sharp objects
- Stay in designated areas/follow marked paths
- Work in pairs/groups for safety
- Be aware of tides and water levels
- Wash hands after handling water samples
Award 1 mark each for two appropriate safety measures

Presenting results: Use line graphs to show relationship between distance and each water quality measure, or create a table with calculations (2 marks)
Award 2 marks each for appropriate responses in each category
20. Evaluate reliability of one day's data and suggest improvements. [4 marks]
Evaluation: One day's data is not reliable because water quality can vary with weather, tides, and daily activities (2 marks)
