Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. Which metal commonly used in drink cans can be melted down and recycled repeatedly with up to 95% less energy than making it from raw bauxite ore: aluminium or coal?
Aluminium
Recycling aluminium saves roughly 95% of the energy required for primary smelting.
2. 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.
3. 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.
4. 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.
5. What device converts sunlight directly into electricity using semiconductor cells: a photovoltaic solar panel or a diesel generator?
Photovoltaic solar panel
Photovoltaic cells convert light photons directly into electrical current.
6. Is crude oil (petroleum) extracted from underground reservoirs a renewable or non-renewable resource?
Non-renewable
Crude oil is a finite fossil fuel resource.
7. What rock ore is mined as the primary raw material for extracting aluminium metal: bauxite or chalk?
Bauxite
Bauxite is the principal aluminium ore.
8. 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).
9. Is wind power captured by wind turbines a renewable or non-renewable energy resource?
Renewable
Wind is continuously generated by uneven solar heating of Earth’s atmosphere.
10. Is coal formed from ancient buried plants over millions of years a renewable or non-renewable resource?
Non-renewable
Coal is a fossil fuel that takes millions of years to form and cannot be replaced quickly.
11. 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.
12. 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.
