Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. What do we call collecting rainwater from roofs into storage tanks for household use: rainwater harvesting or desalination?
Rainwater harvesting
Rainwater harvesting captures clean precipitation before it runs off.
2. In the “3 Rs” of waste reduction (Reduce, Reuse, Recycle), which action prevents waste from being created in the first place: Reduce or Recycle?
Reduce
Reducing consumption avoids using raw materials and energy from the outset.
3. Which greenhouse gas is released in large quantities when fossil fuels (coal, oil and gas) are burned: carbon dioxide or argon?
Carbon dioxide
Combustion of carbon-based fuels oxidises carbon into carbon dioxide (CO₂).
4. Does switching from incandescent bulbs to LED bulbs use less electrical energy for the same brightness (Yes / No)?
Yes
LEDs convert a much higher proportion of electrical energy into light rather than waste heat.
5. Is crude oil (petroleum) extracted from underground reservoirs a renewable or non-renewable resource?
Non-renewable
Crude oil is a finite fossil fuel resource.
6. Is geothermal energy drawn from heat inside Earth’s crust a renewable or non-renewable energy resource?
Renewable
Earth’s internal heat is continuously produced and replenished.
7. Is tidal energy generated by the rise and fall of ocean tides a renewable or non-renewable resource?
Renewable
Ocean tides are reliably driven by the gravitational pull of the Moon and Sun.
8. What happens when too many fish are caught faster than the population can reproduce: overfishing (stock depletion) or eutrophication?
Overfishing (stock depletion)
Harvesting beyond maximum sustainable yield depletes fish populations.
9. Why is fresh groundwater on small coral islands a delicate resource that must not be over-pumped: saltwater intrusion can spoil the freshwater lens, or it turns into lava?
Saltwater intrusion can spoil the freshwater lens
Freshwater floats as a thin lens above denser seawater; over-extraction draws salt water in.
10. Is hydroelectric power generated by flowing river water a renewable or non-renewable energy resource?
Renewable
The water cycle continually replenishes river flow through rainfall.
11. What do we call organic kitchen and garden waste (such as fruit peels and leaves) decomposed into nutrient-rich soil improver: compost or plastic?
Compost
Composting recycles organic matter into humus for soil.
12. Why does planting coastal mangroves and vegetation help protect islands: roots bind sand and buffer wave erosion, or they increase wave height?
Roots bind sand and buffer wave erosion
Coastal vegetation stabilises shorelines and absorbs wave energy.
