Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. 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.
2. 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.
3. 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.
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. 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.
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. Is crude oil (petroleum) extracted from underground reservoirs a renewable or non-renewable resource?
Non-renewable
Crude oil is a finite fossil fuel resource.
8. 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.
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. 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.
11. Is solar energy from sunlight a renewable or non-renewable energy resource?
Renewable
Sunlight is continuously replenished by the Sun on human timescales.
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.
