Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. 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.
2. What rock ore is mined as the primary raw material for extracting aluminium metal: bauxite or chalk?
Bauxite
Bauxite is the principal aluminium ore.
3. 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.
4. What term describes meeting present human needs without compromising the ability of future generations to meet their own needs: sustainability or deforestation?
Sustainability
Sustainability balances environmental, social and economic stewardship over time.
5. 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.
6. Why is pole-and-line tuna fishing (practised in the Maldives) considered more sustainable than large drift nets: it catches fish one by one with minimal bycatch, or it scrapes the seabed?
It catches fish one by one with minimal bycatch
Pole-and-line fishing avoids accidental capture of turtles, sharks and dolphins.
7. 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).
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 erosion
Coastal vegetation stabilises shorelines and absorbs wave energy.
9. 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.
10. Is solar energy from sunlight a renewable or non-renewable energy resource?
Renewable
Sunlight is continuously replenished by the Sun on human timescales.
11. 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.
12. 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.
