Chapter 5- Energy Resources

5. The process of reusing materials to reduce waste and conserve resources, like turning old paper into new paper.
6. Energy Energy produced by splitting atoms, often used to generate electricity in power plants.
10. Energy Energy from the sun that can be used for heat and electricity.
11. Resources Resources that take millions of years to form and cannot be replaced quickly, like coal, oil, and natural gas.
13. Mining A type of mining where layers of earth are removed to reach coal or minerals near the surface.
14. Organic materials, like wood or food waste, that can be burned or converted into energy.
17. Energy Energy made by moving water, like from dams, to generate electricity.
19. Precipitation Rain or snow that has high levels of acid from pollution, which can harm plants, animals, and buildings.

1. A liquid fossil fuel, also called oil, used to make gasoline and other products.
2. Resources Different sources of energy used to produce power, such as fossil fuels, sunlight, and wind.
3. Fuels Energy sources made from ancient plants and animals that were buried and changed over millions of years, like coal, oil, and natural gas.
4. Resources Resources that can be replaced naturally over time, like sunlight, wind, and trees.
7. Gas A fossil fuel in gas form, used for heating and electricity.
8. Energy Heat energy from inside the Earth, used for warming buildings or producing electricity.
9. A fuel made by mixing gasoline with alcohol from plants, like corn.
12. Resources Materials from Earth that people use to survive and improve their lives, like water, trees, and minerals.
15. A mix of smoke and fog caused by pollution in the air, making it hard to breathe.
16. Energy Energy created by wind turning large blades on wind turbines to produce electricity.
18. A black rock that is burned for energy. It forms from ancient plant material buried underground.
