Secondary 1 Geography Quiz - Resources Sustainability (Answer Key)

Total Marks: 40
Topic: Resources Sustainability

---

Section A: Multiple Choice

1. D (1 mark)
   Teaching note: Singapore’s Four National Taps are local catchment, imported water, NEWater, desalination. "Rainforest collection" is not a tap. Common mistake: choosing NEWater as not real.

2. B (1 mark)
   Mangrove roots trap sediment and weaken waves, protecting coast from erosion.

3. B (1 mark)
   Water cycles but total store is fixed; local supply can be limited.

4. A (1 mark)
   Cutting forests releases carbon stored in trees → more greenhouse gases.

5. B (1 mark)
   Desalination makes fresh water from sea, a sustainable tech strategy.

Section B: Short Answer & Data

6. Solid (ice) or gas (water vapour) (1 mark)
   Any one correct state.

7. 1423 (1 mark)
   Easting 14 first, northing 23 second (lower-left of reservoir square).

8. 10 m (1 mark)
   30 m − 20 m = 10 m contour interval.

9. Any two: habitation, raw materials, recreation, food (2 marks, 1 each)
   e.g., (a) timber (b) tourism.

10. Pattern: Daily water use per person fell from 155 L (2010) to 140 L (2020). Decrease of 15 L over 10 years. Steady decline. (3 marks: identify start/end 1, trend 1, value use 1)

11. To breathe in oxygen-poor muddy soil / support in soft ground (2 marks: 1 for oxygen, 1 for support)

12. Site X (1); higher dissolved oxygen supports aquatic life, less pollution (1). (2 marks)

13. In tree biomass / soil / leaves (1 mark)

14. (a) Coast erosion protection (b) Habitat for fish / carbon storage (2 marks)

15. Sewage, factory waste, oil spill, litter (1 mark, any one)

---

Section C: Structured Response

16. (a) Continuous movement of water between land, ocean, air (1 mark)
    (b) Dry season → less rain input, evaporation continues → water budget deficit; reservoir levels drop. (3 marks: less input 1, output continues 1, result 1)

17. (a) Rose from 140 to 210 million gallons/day (2000–2020), increasing trend (2 marks)
    (b) Population growth / more households (2 marks, reasoned)

18. Biodiversity: many species in layers (emergent, canopy). Climate: store carbon, release O2. (4 marks: 2 each, with examples)

19. NEWater: recycles used water, reduces import need. Desalination: sea water, weather-independent. (4 marks: 2 each with explanation)

20. Not sustainable: loses coastal protection, habitat, carbon store. Short-term jobs vs long-term harm. (4 marks: counter 2, reason 2)
