Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. Why are single-use plastics harmful to marine ecosystems: they persist for centuries and break into microplastics, or they dissolve into oxygen?
They persist for centuries and break into microplastics
Conventional plastics do not biodegrade readily and fragment into harmful microplastics.
2. 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.
3. 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.
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. 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.
6. 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.
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. Is solar energy from sunlight a renewable or non-renewable energy resource?
Renewable
Sunlight is continuously replenished by the Sun on human timescales.
9. 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.
10. 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.
11. 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.
12. 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.
