Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. Is crude oil (petroleum) extracted from underground reservoirs a renewable or non-renewable resource?
Non-renewable
Crude oil is a finite fossil fuel resource.
2. 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).
3. 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.
4. 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.
5. Is natural gas (mainly methane) trapped in rock layers a renewable or non-renewable resource?
Non-renewable
Natural gas is a finite fossil fuel.
6. 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.
7. 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.
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. 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.
10. What rock ore is mined as the primary raw material for extracting aluminium metal: bauxite or chalk?
Bauxite
Bauxite is the principal aluminium ore.
11. 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.
12. 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.
