Total Marks: 40
Section A: Map Reading (8 marks)
Q1. 2152
Teaching note: Read easting (21) first, then northing (52). Common mistake: reversing order. [1]
Q2. 316637 (acceptable 316636–316638)
Method: 4-fig = 3163, school at 6/10 east, 7/10 north → 316637. [1]
Q3. 10 m
Method: Difference between adjacent labelled contours (20–10). [1]
Q4. 4252
Forest east of bridge at 4152 → grid square 4252. [1]
Q5. 2761
Highest spot height 180 m at that grid. [1]
Q6. 503544
Junction at 3/10 east, 4/10 north of 5035. [1]
Q7. 5 m
Contours 5,10,15 → interval 5 m. [1]
Q8. 1431
Lake south of hill 1432 → 1431. [1]
Section B: Data Interpretation (12 marks)
Q9. Jupiter
Table shows 95 moons, highest. [1]
Q10. [2 total]
- Pattern 1: Number of moons increases with distance from Sun (Mercury 0 → Jupiter 95). [1]
- Pattern 2: Diameter is largest for Jupiter (142984 km) and smaller for inner planets. [1]
Marking: 1 mark each clear pattern with evidence.
Q11. [3]
- Water use fell from 158 L (2010) to 143 L (2020). [1]
- Steady decrease over time. [1]
- Drop of 15 L per person per day. [1]
Marking descriptors: trend stated (1), evidence used (1), quantification (1).
Q12. [3]
Site X (forest stream) healthier. [1]
Reason 1: Lower turbidity (2 NTU vs 15) = clearer water. [1]
Reason 2: Higher dissolved oxygen (8 vs 4 mg/L) = better for aquatic life. [1]
Q13. [2]
Year: 2020 [1]; Amount: 2800 mm [1].
Q14. [3]
Mean = (26+28+27+27) / 4 = 108/4 = 27 °C. [2 for calculation, 1 for unit/answer]
Step-by-step: sum = 108, divide by 4.
Section C: Graph and Map Application (20 marks)
Q15. [3]
Landform: Hill. [1]
Explanation: Concentric contours with values increasing to centre (100→160 m). [1]
Summit ~160 m, slopes all around. [1]
Q16. [4]
- Water consumption decreased (160→140 L). [1]
- Population increased (4.0→5.7 million). [1]
- Opposite trends. [1]
- Singapore reduced per capita use despite growth. [1]
Q17. [2]
4-fig school: 2963 [1]; 6-fig temple: 303633 [1].
Q18. [4]
Method 1: Measure turbidity with tube — shows suspended particles, suits comparing clarity. [2]
Method 2: Test dissolved oxygen with kit — indicates pollution level, suits health check. [2]
Q19. [2]
416548 (or 417547–417549). Northernmost in square = higher northing. [2]
Q20. [5]
- As temperature rises, visitors increase. [1]
- 24°C→120, 33°C→400. [1]
- Positive relationship. [1]
- From 24 to 33°C, visitors more than triple. [1]
- Likely warmer weather attracts park visitors. [1]
Marking: description (2), data evidence (2), conclusion (1).
