Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. Is solar energy from sunlight a renewable or non-renewable energy resource?
Renewable
Sunlight is continuously replenished by the Sun on human timescales.
2. Is natural gas (mainly methane) trapped in rock layers a renewable or non-renewable resource?
Non-renewable
Natural gas is a finite fossil fuel.
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. 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.
5. 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.
6. Is geothermal energy drawn from heat inside Earth’s crust a renewable or non-renewable energy resource?
Renewable
Earth’s internal heat is continuously produced and replenished.
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. 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.
9. 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.
10. 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.
11. 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.
12. What do we call organic kitchen and garden waste (such as fruit peels and leaves) decomposed into nutrient-rich soil improver: compost or plastic?
Compost
Composting recycles organic matter into humus for soil.
