Answers
Secondary 1 Geography Quiz - Resources Sustainability
Answer Key
Section A: Multiple Choice Questions
1. C — Solar energy [1]
Explanation: Solar energy is renewable because it is continuously replenished by the sun. Natural gas, coal, and petroleum are fossil fuels that take millions of years to form.
2. B — Agricultural expansion [1]
Explanation: The leading cause of tropical deforestation globally is the clearing of land for agriculture, including cattle ranching and palm oil plantations.
3. B — A resource that takes millions of years to form [1]
Explanation: Non-renewable resources such as fossil fuels and minerals form over geological timescales and cannot be replenished within a human lifetime.
4. B — Desertification [1]
Explanation: Desertification is the degradation of land in dry areas due to factors such as drought, deforestation, and inappropriate agriculture.
5. B — Rainwater harvesting [1]
Explanation: Rainwater harvesting captures and stores rainwater for later use, reducing reliance on other water sources and promoting sustainability.
6. C — Carbon dioxide [1]
Explanation: Carbon dioxide (CO₂) is the primary greenhouse gas emitted through human activities such as burning fossil fuels, contributing most to global warming.
7. C — Recycling aluminium cans [1]
Explanation: Recycling reduces the need to extract raw materials, saves energy, and decreases waste sent to landfills.
8. B — Depletion of marine resources [1]
Explanation: Overfishing removes fish faster than populations can reproduce, leading to declining fish stocks and disruption of marine ecosystems.
9. C — Food shortages [1]
Explanation: When resources such as fertile soil, water, or fish stocks are depleted, the ability to produce food is reduced, leading to shortages.
10. B — Reduce, Reuse, Recycle [1]
Explanation: The 3Rs are a widely promoted waste management hierarchy that encourages minimising waste generation.
Section B: Short Answer Questions
11. [2]
A renewable resource is a natural resource that can be replenished naturally within a human lifetime. [1]

Marking note: Award 1 mark for a correct definition and 1 mark for a valid example. Accept any reasonable renewable resource.
12. [2]
(a) Forests absorb carbon dioxide and release oxygen, helping to regulate the atmosphere / reduce greenhouse gases. [1]
(b) Forests provide habitats for a wide variety of plants and animals, supporting biodiversity. [1]
Alternative acceptable answers for (a) or (b):
- Forests help prevent soil erosion by stabilising soil with their roots.
- Forests play a role in the water cycle through transpiration.
- Forests provide resources such as timber, food, and medicine for humans.
13. [3]
Sustainable development means meeting the needs of the present generation without compromising the ability of future generations to meet their own needs. [1]
It involves using resources in a way that balances economic growth, [1] environmental protection, and social well-being. [1]
Marking note: Award 1 mark for the core definition, 1 mark for mentioning balance of needs across generations, and 1 mark for reference to balancing economic/environmental/social factors.
14. [4]
(a) Country C [1]
(b) Total = 12.5 + 8.3 + 15.7 + 6.1 = 42.6 million tonnes [2]
Marking note: Award 1 mark for correct working and 1 mark for correct final answer. If working is shown but final answer has a minor arithmetic error, award 1 mark for method.
(c) The country can encourage recycling / implement a plastic bag tax / promote the use of reusable products / enforce stricter waste reduction policies. [1]
Marking note: Accept any reasonable suggestion.
15. [4]
(a) Effect 1: Water pollution can kill aquatic organisms such as fish and coral, disrupting ecosystems and reducing biodiversity. [2]
Marking note: Award 1 mark for identifying the effect and 1 mark for explaining the consequence.
(b) Effect 2: Polluted water can contaminate drinking water supplies, posing health risks to humans and animals / lead to algal blooms that deplete oxygen in water bodies (eutrophication). [2]
Marking note: Award 1 mark for identifying the effect and 1 mark for explaining the consequence. Accept any valid effect of water pollution.
Section C: Structured Response Questions
16. [6]
(a) Any one of: local catchment water / imported water / NEWater / desalinated water. [1]
(b) Singapore needs to import most of its water because it is a small island with limited land area for water catchments / limited natural freshwater sources such as rivers and lakes / a large population that creates high demand exceeding local supply. [2]
Marking note: Award 1 mark for identifying limited land/natural sources and 1 mark for linking to demand exceeding supply.
(c) NEWater is produced by treating used water (wastewater) to ultra-clean, high-grade reclaimed water using advanced membrane technologies and ultraviolet disinfection. [1] This reduces Singapore's dependence on imported water by providing an additional, reliable source of clean water. [1] It is a sustainable method because it recycles water that would otherwise be wasted, ensuring a continuous supply even during dry periods. [1]
Marking note: Award 1 mark for describing the process, 1 mark for explaining reduced import dependence, and 1 mark for linking to sustainability.
17. [4]
Way 1: Reduce the use of single-use plastics (e.g., bring reusable bags when shopping). [1]
How it helps: This reduces the amount of plastic waste that ends up in landfills or oceans, reducing pollution and harm to wildlife. [1]
Way 2: Conserve water at home (e.g., turning off the tap while brushing teeth, taking shorter showers). [1]
How it helps: This reduces water consumption, helping to preserve freshwater resources and ensuring there is enough water for future needs. [1]
Alternative acceptable answers:
- Using public transport / cycling instead of driving → reduces carbon emissions and air pollution.
- Recycling paper, plastic, and metal → reduces waste and conserves raw materials.
- Switching off lights and appliances when not in use → saves energy and reduces fossil fuel consumption.
- Buying locally produced food → reduces carbon footprint from transportation.
Marking note: Award 1 mark for each valid way and 1 mark for each correct explanation of environmental benefit (2 + 2 = 4 marks).
18. [4]
(a) Evaporation [1]
(b) Condensation [1]
(c) The water cycle is important because it distributes fresh water across the Earth through precipitation, [1] which is essential for drinking, agriculture, and sustaining all living organisms. It also regulates temperature and supports ecosystems. [1]
Marking note: For (c), award 1 mark for explaining distribution of fresh water and 1 mark for linking to sustaining life/ecosystems.
19. [5]
Environmental Impact 1: Soil erosion — When trees are removed, the soil is no longer held in place by roots. Rain washes away the topsoil, making the land less fertile and prone to landslides. [1]
Environmental Impact 2: Loss of biodiversity — Tropical rainforests are home to millions of species. Deforestation destroys habitats, leading to the extinction of plants and animals. [1]
Environmental Impact 3 (bonus): Increased atmospheric CO₂ — Trees absorb CO₂. When they are cut down or burned, stored carbon is released, contributing to global warming. [1]
Social Impact: Indigenous communities lose their traditional way of life — These communities depend on the forest for food, shelter, medicine, and cultural practices. Deforestation forces them to relocate and lose their livelihoods and heritage. [1]
Marking note: Award up to 3 marks for environmental impacts (any two well-explained = 2 marks; a third valid point = 1 bonus mark within the cap) and 1 mark for a well-explained social impact. Award 1 additional mark for overall structure, use of examples, or evaluative language (e.g., "this is unsustainable because…"). Total = 5 marks.
20. [5]
(a) Advantage of Option A (coal-fired power plant): It is cheaper to build and operate / provides a reliable and consistent supply of electricity. [1]
Disadvantage of Option A: It produces high levels of carbon dioxide and other pollutants, contributing to global warming and air pollution / it relies on a non-renewable resource (coal) that will eventually run out. [1]
(b) I would recommend Option B (solar energy) because:
Reason 1: Solar energy is a renewable and clean source of power. It does not produce carbon emissions during operation, which helps combat climate change and reduces air pollution. [1]
Reason 2: Although the initial cost is high, solar energy has low operating costs in the long run because sunlight is free. Over time, the town will save money on fuel costs and reduce its dependence on expensive imported fossil fuels. [1]
Alternative valid reason: Solar panels have a long lifespan and require minimal maintenance, making them a sustainable long-term investment.
Marking note: Award 1 mark for a valid advantage, 1 mark for a valid disadvantage, 1 mark for stating the recommended option, and up to 2 marks for well-explained reasons. If the student chooses Option A but provides valid, well-reasoned justification, award marks accordingly.
