Renewable & non-renewable resources
Answers and reasoning. Review before teaching.
1. 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.
2. 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.
3. 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.
4. 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.
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 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.
7. 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.
8. 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.
9. 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.
10. Is solar energy from sunlight a renewable or non-renewable energy resource?
Renewable
Sunlight is continuously replenished by the Sun on human timescales.
11. 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.
12. 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.
