Across
- 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
Down
- 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
