Renewable & non-renewable resources
Take your time. Show your thinking.
1. What happens when too many fish are caught faster than the population can reproduce: overfishing (stock depletion) or eutrophication?
2. What mineral ore is smelted in a blast furnace to produce iron and steel: hematite (iron ore) or halite?
3. Is coal formed from ancient buried plants over millions of years a renewable or non-renewable resource?
4. Does switching from incandescent bulbs to LED bulbs use less electrical energy for the same brightness (Yes / No)?
5. In the “3 Rs” of waste reduction (Reduce, Reuse, Recycle), which action prevents waste from being created in the first place: Reduce or Recycle?
6. What rock ore is mined as the primary raw material for extracting aluminium metal: bauxite or chalk?
7. Is hydroelectric power generated by flowing river water a renewable or non-renewable energy resource?
8. Why does planting coastal mangroves and vegetation help protect islands: roots bind sand and buffer wave erosion, or they increase wave height?
9. What do we call collecting rainwater from roofs into storage tanks for household use: rainwater harvesting or desalination?
10. Is wind power captured by wind turbines a renewable or non-renewable energy resource?
11. Is geothermal energy drawn from heat inside Earth’s crust a renewable or non-renewable energy resource?
12. Is crude oil (petroleum) extracted from underground reservoirs a renewable or non-renewable resource?

Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. 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.
2. What mineral ore is smelted in a blast furnace to produce iron and steel: hematite (iron ore) or halite?
Hematite (iron ore)Hematite (Fe₂O₃) is a major iron ore.
3. Is coal formed from ancient buried plants over millions of years a renewable or non-renewable resource?
Non-renewableCoal is a fossil fuel that takes millions of years to form and cannot be replaced quickly.
4. Does switching from incandescent bulbs to LED bulbs use less electrical energy for the same brightness (Yes / No)?
YesLEDs convert a much higher proportion of electrical energy into light rather than waste heat.
5. In the “3 Rs” of waste reduction (Reduce, Reuse, Recycle), which action prevents waste from being created in the first place: Reduce or Recycle?
ReduceReducing consumption avoids using raw materials and energy from the outset.
6. What rock ore is mined as the primary raw material for extracting aluminium metal: bauxite or chalk?
BauxiteBauxite is the principal aluminium ore.
7. Is hydroelectric power generated by flowing river water a renewable or non-renewable energy resource?
RenewableThe water cycle continually replenishes river flow through rainfall.
8. 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 erosionCoastal vegetation stabilises shorelines and absorbs wave energy.
9. What do we call collecting rainwater from roofs into storage tanks for household use: rainwater harvesting or desalination?
Rainwater harvestingRainwater harvesting captures clean precipitation before it runs off.
10. Is wind power captured by wind turbines a renewable or non-renewable energy resource?
RenewableWind is continuously generated by uneven solar heating of Earth’s atmosphere.
11. Is geothermal energy drawn from heat inside Earth’s crust a renewable or non-renewable energy resource?
RenewableEarth’s internal heat is continuously produced and replenished.
12. Is crude oil (petroleum) extracted from underground reservoirs a renewable or non-renewable resource?
Non-renewableCrude oil is a finite fossil fuel resource.
