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. 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 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. 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.
5. 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.
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. In the “3 Rs” of waste reduction (Reduce, Reuse, Recycle), which action prevents waste from being created in the first place: Reduce or Recycle?
Reduce
Reducing consumption avoids using raw materials and energy from the outset.
8. 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.
9. 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.
10. When timber is harvested only at the rate that new trees are planted and grown to maturity, that forest management is called: sustainable or extractive?
Sustainable
Sustainable forestry maintains forest cover and biodiversity for future generations.
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. 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.
