2. What is the contour interval shown on this map? [1 mark] Answer: 5m (or 10m depending on map scale) Award 1 mark for correct interval

3. State the 6-figure grid reference of sampling point B. [1 mark] Answer: 234654 (or appropriate 6-figure reference) Award 1 mark for correct 6-figure grid reference

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

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)

Marking Notes:

• Accept alternative valid answers where appropriate
• Award marks for geographical terminology used correctly
• Look for evidence-based responses that reference figures/data provided
