Answers

O-Level Geography Quiz - Resources Sustainability (Answer Key)

Total Marks: 40
Topic: Resources Sustainability
Level: O-Level

Section A: Short Answer

Q1 [2 marks]
Answers: (1) Freshwater is renewed by the water cycle (evaporation, precipitation) so it is renewable; (2) It is finite because total usable freshwater is limited by storage and pollution, and overuse exceeds recharge rate.
Teaching note: Renewable means naturally replenished; finite means limited stock. Student must show both ideas.
Marking: 1 mark each point.

Q2 [1 mark]
Answer: The total volume of freshwater used directly and indirectly to produce goods and services consumed by a person or community.
Teaching note: Link to virtual water in food/products.

Q3 [2 marks]
Answers: Coal, oil, natural gas (any two).
Marking: 1 mark each.

Q4 [1 mark]
Answer: A situation where all people have physical and economic access to sufficient safe and nutritious food.
Teaching note: Must include access + quantity + quality.

Q5 [2 marks]
Answer: e.g., Reduces food miles and transport energy; uses vacant rooftops; lowers import dependence. (Any one explained = 2 marks)
Teaching note: Connect to energy/land use.

Q6 [1 mark]
Answer: e.g., UN Sustainable Development Goals (SDG 12), Paris Agreement (indirect), ASEAN Agreement on Transboundary Haze (any valid).

Q7 [2 marks]
Answers: Land subsidence, saltwater intrusion, aquifer depletion (any two).
Marking: 1 mark each.

Q8 [1 mark]
Answer: Reduce, Reuse, Recycle.

Section B: Data & Source Interpretation

Q9 [3 marks]
Working: 136 000 m³ ÷ 8 000 households = 17 m³/household/month.
Answer: 17 m³.
Marking: 1 mark working, 2 marks correct answer with unit.
Common mistake: Dividing households by use.

Q10 [2 marks]
Town A: 150k/10k=15; B:17; C:156k/12k=13. Lowest = Town C at 13 m³.
Marking: 1 mark town, 1 mark value.

Q11 [3 marks]
Answers: (1) Exporting 80% timber while forests shrink; (2) Issuing logging licences despite loss; (3) Replanting slower than loss. (Any two = 2 marks + 1 for clear identification)
Marking: 1.5 each up to 3.

Q12 [2 marks]
Answer: e.g., Logging continues so loss > gain; trees take years to mature; monoculture may reduce biodiversity.
Marking: 2 marks for reasoned link.

Q13 [3 marks]
Country: Q (42%). Difference: 42% – 8% = 34%.
Marking: 1 mark country, 2 marks difference with working.

Q14 [2 marks]
Answer: Solar is clean (no CO₂ when operating), inexhaustible; coal emits greenhouse gases and is finite.
Marking: 1 mark point, 1 mark contrast.

Q15 [3 marks]
Answer: Industrial Zone 1 wastewater flows into reservoir → contaminates water supply; spatial proximity (12 km) risks sustainability.
Marking: 1 mark relationship, 2 marks explanation.

Section C: Structured & Extended Response

Q16 [3 marks]
Answers: Desalinisation converts seawater to drinkable water, adding to supply (1). Reduces rain dependence (1). Limitation: high energy cost / brine waste (1).
Marking descriptors: 3 = all three; 2 = two.

Q17 [4 marks]
Position: Not alone (1). Reason: recycling handles waste but not extraction of new materials (1); need reduce/reuse (1); behavioural and tech limits (1).
Marking: 4 = balanced eval; 2–3 = partial.

Q18 [3 marks]
Working: (90+70+85)÷3 = 245÷3 = 81.67%.
Answer: 81.7% (or 81.67%).
Marking: 1 working, 2 answer.

Q19 [3 marks]
Answers: Composting, water-saving taps, solar panels, green procurement (any two explained).
Marking: 1.5 each.

Q20 [5 marks]
Content: Tech (efficiency, alternatives) helps (2); examples: LED, vertical farm (1); but not total fix due to rebound effect, equity (1); conclusion balanced (1).
Marking descriptors: 5 = eval + examples + conclusion; 3–4 = partial.
