- Fossil fuels are primarily composed of coal, oil, and natural gas.
-
Answer: natural gas
---
3. _______ energy resources can be used repeatedly and are replaced naturally.
- Energy resources that can be used repeatedly and are naturally replenished are called
renewable energy sources.
-
Answer: Renewable
---
4. _______ power uses the energy from the Sun to heat water or make electricity.
- Solar power involves capturing energy from the Sun to generate heat or electricity.
-
Answer: Solar
