Answers
Secondary 1 Geography Quiz — Resources Sustainability
Answer Key
Section A: Understanding Resources (Questions 1–5)
1. Define the term natural resource.
Answer: A natural resource is any material or substance found in the environment that is useful to humans. [1]
Marking note: Award 1 mark for a clear definition that includes the idea of something from nature that is useful to people. Accept examples as part of the definition but the definition itself must be present.
2. State one difference between a renewable resource and a non-renewable resource.
Answer: A renewable resource can be replenished naturally within a human lifetime (e.g., solar energy, timber), whereas a non-renewable resource cannot be replenished within a human lifetime and will eventually run out (e.g., fossil fuels, minerals). [1]
Marking note: Award 1 mark for any valid distinguishing difference. The key idea is that renewable resources can be replaced/regenerated, while non-renewable ones cannot.
3. The table below shows four resources. Place a tick (✓) in the correct column for each resource.
| Resource | Renewable | Non-renewable |
|---|---|---|
| Solar energy | ✓ | |
| Natural gas | ✓ | |
| Timber (wood) | ✓ | |
| Crude oil | ✓ |
[2]
Marking note: Award 1 mark for each pair correctly completed. Deduct if a resource has ticks in both columns. All four must be correct for 2 marks; two or three correct = 1 mark; fewer than two correct = 0 marks.
4. Give one example of how people in Singapore depend on water as a resource in their daily lives.
Answer: Any one of the following (or similar valid example):
- Drinking and cooking
- Washing and bathing
- Flushing toilets
- Cleaning and household use
- Industrial/manufacturing processes
[1]
Marking note: Award 1 mark for any reasonable daily use of water. Accept any valid example.
5. What does the term sustainable use of resources mean?
Answer: Using resources in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. [1]
Marking note: Award 1 mark for conveying the idea of using resources wisely so they last for the future. Accept paraphrases such as "using resources carefully so they do not run out" or "using resources in a way that can continue over a long time."
Section B: Water Resources and Sustainability (Questions 6–12)
6. (a) Name Process A — the change of water from liquid to water vapour.
Answer: Evaporation [1]
(b) Name Process B — water falling from clouds onto the land surface.
Answer: Precipitation [1]
Marking note: Accept "rainfall" or "rain" as an alternative to precipitation.
(c) Explain why the water cycle is important for maintaining freshwater supplies on land.
Answer: The water cycle continuously recycles water through evaporation, condensation, and precipitation. This process replenishes freshwater sources on land such as rivers, lakes, and groundwater, ensuring that freshwater is available for humans, animals, and plants over time. [2]
Marking note: Award 2 marks for a clear explanation that links the water cycle to the replenishment of freshwater. Award 1 mark for a partial answer that mentions the water cycle but does not clearly explain how it maintains freshwater supplies.
7. Singapore has four main sources of water, known as the "Four National Taps." State two of these four sources.
Answer: Any two of the following:
(i) Local catchment water [1]
(ii) Imported water [1]
(iii) NEWater (recycled water)
(iv) Desalinated water
Marking note: Award 1 mark for each correct source, up to a maximum of 2 marks.
8. Explain one reason why Singapore needs to diversify its water sources instead of relying on only one source.
Answer: Any one of the following (or similar valid reason):
- If one source fails (e.g., drought reduces catchment water, or a problem arises with imported water supply), other sources can still provide water, ensuring water security.
- Diversification reduces dependence on any single source, making the water supply more reliable and resilient.
- As Singapore's population and economy grow, demand for water increases, so multiple sources are needed to meet the growing demand.
[2]
Marking note: Award 2 marks for a well-explained reason with clear reasoning. Award 1 mark for a valid reason that lacks development or explanation.
9. (a) Which sector uses the most water?
Answer: Agriculture [1]
(b) Calculate the total amount of water used by all four sectors.
Answer: 320 + 180 + 90 + 60 = 650 billion litres [1]
Marking note: Award 1 mark for the correct total. Accept 650 (billion litres) without units, but the working must be shown or implied.
(c) Suggest one way the sector that uses the most water could reduce its water consumption.
Answer: Any one of the following (or similar valid suggestion):
- Farmers could use drip irrigation instead of flood irrigation to reduce water wastage.
- Farmers could grow crops that require less water.
- Water-efficient farming techniques could be adopted.
[2]
Marking note: Award 2 marks for a specific, practical suggestion clearly linked to reducing water use in agriculture. Award 1 mark for a vague or generic answer such as "use less water" without specifying how.
10. Describe two ways in which human activities can pollute freshwater sources such as rivers and reservoirs.
Answer: Any two of the following (or similar valid points):
(i) Industrial waste/chemicals being discharged into rivers [1]
(ii) Sewage being released into water bodies without proper treatment
(iii) Agricultural runoff containing fertilisers and pesticides entering rivers
(iv) Oil spills from ships or vehicles
(v) Littering and dumping of rubbish into rivers or reservoirs
Marking note: Award 1 mark for each valid way, up to a maximum of 2 marks. The answer must describe the activity and link it to pollution of freshwater.
11. Explain why it is important to keep reservoirs and rivers clean for a country like Singapore.
Answer: Singapore has limited land and water resources. Keeping reservoirs and rivers clean ensures that the water collected can be treated and used as drinking water. Polluted water is more expensive and difficult to treat. Clean water sources also support biodiversity and recreational activities. [2]
Marking note: Award 2 marks for a well-developed explanation that refers to Singapore's context (limited resources, need for clean drinking water). Award 1 mark for a general answer that does not specifically address Singapore's situation.
12. NEWater is an important source of water in Singapore. Describe the process used to produce NEWater from used water.
Answer: Used water (sewage) is collected and treated at water reclamation plants. It then undergoes advanced purification through microfiltration/ultrafiltration, reverse osmosis (where water is forced through a special membrane to remove impurities), and ultraviolet disinfection (to kill any remaining bacteria and viruses). The resulting water is very clean and safe for use. [3]
Marking note: Award 3 marks for a clear, sequential description that includes at least three key stages (collection/treatment, reverse osmosis/advanced purification, and disinfection). Award 2 marks for describing two stages. Award 1 mark for mentioning only one stage or a very general answer.
Section C: Energy Resources and Sustainability (Questions 13–17)
13. State two examples of renewable energy sources.
Answer: Any two of the following:
(i) Solar energy [1]
(ii) Wind energy
(iii) Hydroelectric power / hydropower
(iv) Geothermal energy
(v) Biomass / biofuel
Marking note: Award 1 mark for each correct example, up to a maximum of 2 marks. Do not accept fossil fuels (coal, oil, natural gas) as renewable.
14. Fossil fuels such as coal, oil, and natural gas are non-renewable resources. Explain two environmental problems caused by burning fossil fuels.
Answer: Any two of the following (or similar valid problems):
(i) Air pollution / acid rain — Burning fossil fuels releases harmful gases such as sulphur dioxide and nitrogen oxides, which cause acid rain and smog. [1]
(ii) Global warming / climate change — Burning fossil fuels releases carbon dioxide, a greenhouse gas, which traps heat in the atmosphere and leads to rising global temperatures.
(iii) Health problems — Air pollution from burning fossil fuels can cause respiratory diseases in humans.
Marking note: Award 1 mark for each valid environmental problem with a brief explanation, up to a maximum of 2 marks. The problem must be environmental (not economic).
15. Explain one advantage and one disadvantage of using natural gas compared to coal.
Answer:
Advantage: Natural gas produces less carbon dioxide and fewer pollutants (such as sulphur dioxide) than coal when burned for the same amount of energy, so it causes less air pollution. [1]
Disadvantage: Natural gas is still a fossil fuel and still releases carbon dioxide when burned, so it still contributes to global warming. / Natural gas is non-renewable and will eventually run out. / Natural gas (methane) is a potent greenhouse gas if it leaks during extraction and transportation. [1]
Marking note: Award 1 mark for a valid advantage and 1 mark for a valid disadvantage. Both must compare natural gas to coal or explain a drawback of natural gas.
16. (a) What percentage of energy comes from renewable sources?
Answer: Solar (10%) + Wind (5%) = 15% [1]
Marking note: Award 1 mark for the correct answer. Working is not required but the answer must be 15%.
(b) Suggest one reason why Country X still relies heavily on non-renewable energy sources.
Answer: Any one of the following (or similar valid reason):
- Renewable energy technology (such as solar panels and wind turbines) is expensive to set up and may not yet be able to meet the country's large energy demands.
- Non-renewable energy sources like coal and oil are well-established and the country already has the infrastructure to use them.
- Renewable energy sources like solar and wind are intermittent (dependent on weather conditions) and may not provide a reliable, constant supply of energy.
[2]
Marking note: Award 2 marks for a well-explained reason. Award 1 mark for a valid but underdeveloped reason.
17. Explain two ways in which individuals in Singapore can help to conserve energy in their daily lives.
Answer: Any two of the following (or similar valid ways):
(i) Switch off lights and electrical appliances when not in use to reduce electricity consumption. [1]
(ii) Use public transport instead of private cars to reduce fuel consumption.
(iii) Set the air conditioner at a higher temperature (e.g., 25°C) to use less energy.
(iv) Use energy-efficient appliances (e.g., LED light bulbs).
Marking note: Award 1 mark for each valid way with a brief explanation, up to a maximum of 2 marks. Answers must be practical and specific to individual actions.
Section D: Managing Resources Sustainably (Questions 18–20)
18. (a) State two effects of deforestation mentioned in the source.
Answer: Any two of the following:
(i) Loss of biodiversity [1]
(ii) Increased flooding
(iii) Higher levels of carbon dioxide in the atmosphere
Marking note: Award 1 mark for each correct effect taken directly from the source, up to a maximum of 2 marks.
(b) Suggest one way countries can manage their forest resources sustainably.
Answer: Any one of the following (or similar valid suggestion):
- Enforce laws that limit or ban illegal logging.
- Implement replanting/reforestation programmes to replace trees that have been cut down.
- Create protected areas/national parks where forests cannot be cleared.
- Encourage sustainable forestry practices such as selective logging instead of clear-cutting.
[2]
Marking note: Award 2 marks for a specific, practical suggestion. Award 1 mark for a vague answer such as "stop cutting down trees" without further detail.
19. Explain why recycling is considered an important strategy for sustainable resource management. In your answer, refer to at least two different resources that can be recycled.
Answer: Recycling reduces the amount of waste sent to landfills and decreases the need to extract new raw materials from the environment, helping to conserve natural resources. For example, paper can be recycled to reduce the need to cut down trees, and metals such as aluminium can be recycled to reduce the need for mining. Recycling also saves energy — producing goods from recycled materials often uses less energy than producing them from raw materials. [3]
Marking note: Award 3 marks for a clear explanation of why recycling is important, with reference to at least two specific recycled resources and at least one reason linked to sustainability. Award 2 marks for mentioning two resources but with limited explanation, or for a good explanation with only one resource. Award 1 mark for a general statement about recycling with no specific resources mentioned.
20. Explain three ways in which Singapore manages its land resources sustainably despite being a small, densely populated country.
Answer: Any three of the following (or similar valid points):
(i) Careful urban planning — Singapore plans land use carefully through the Concept Plan and Master Plan, designating areas for housing, industry, recreation, and green spaces to make the best use of limited land. [1]
(ii) Building upwards (high-rise development) — Singapore builds high-rise housing and commercial buildings to accommodate more people and activities on a limited land area.
(iii) Creating green spaces and parks — Singapore develops parks, nature reserves, and park connectors to maintain biodiversity and provide recreational spaces for residents.
(iv) Reclaiming land — Singapore increases its land area through land reclamation to create more space for development.
(v) Protecting nature reserves — Singapore legally protects areas such as Bukit Timah Nature Reserve and Sungei Buloh Wetland Reserve to conserve biodiversity.
Marking note: Award 1 mark for each valid way with a brief explanation, up to a maximum of 3 marks. Answers must be specific to Singapore's context.
