energy

3. The act of preserving or maintaining the planet and its resources
6. The process by which carbon dioxide and water are converted into glucose ( sugar) by plants, algae, and certain bacteria; uses sunlight energy to produce nutrients
8. Gas- Fossil fuel consisting of methane that occurs naturally underground
9. Energy-Energy stored in atomic bonds that form molecules; released when chemical reactions occur and rearrange those atoms by breaking the bonds
10. Transformation-One form of energy changes to another; allows energy to be used in different ways ( chemical energy in a battery transforms into electric energy in many battery-powered appliances)
13. Energy-Energy of electric charges moving through conductors; powers devices used in daily life
15. Fossil fuel used to produce gasoline and oil
16. Energy-Energy of moving particles or atoms that make up all matter; heated substances have more thermal energy than cooled substances
18. Energy-Energy stored in the nucleus of an atom, released when protons or neutrons are added to or removed from the nucleus
19. Fossil fuel made of mostly carbonized plant matter

1. Energy- Resources consumed by humans much faster than nature can produce ( ex: oil, natural gas)
2. Fuel-Nonrenewable energy source formed from remains of living organisms, which cause pollution ( coal, natural gas, petroleum)
4. Energy- Energy that travels in waves ( ex; microwaves, radio waves, energy from the sun)
5. The ability to do work
7. The upper layer of earth in which plants grow; provide a mixture of nutrients as well as a habitat for many organisms
11. Energy- Energy harnessed from the sun ( radiant light and heat )
12. The process by which glucose is converted to cellular energy often with the use of oxygen
14. Energy- Energy derived from sources that are continually replenished ( wind, solar, biomass, geothermal, hydro-power)
17. Energy- Energy of moving objects, such as a rolling ball, wind or currents
