Across
- 3. energy Produced by the internal heat of the earth.
- 6. energy Moves back and forth from potential (stored) energy to kinetic (moving) energy.
- 10. energy Energy of motion.
- 11. energy Energy from moving molecules, related to heat.
- 13. energy energy Energy obtained by harnessing tidal power.
- 14. Energy Budget Accounts for the balance between the energy that Earth receives from the Sun, and the energy the Earth radiates back into outer space.
- 18. Produced from vegetable oils, animal fats, and other byproducts of human waste.
- 19. energy Types of energy that can be replaced after they have been used. Wind, water, solar, biomass, and geothermal are examples.Tidal energy
- 22. gas A fossil fuel found by drilling, contains primarily methane.
- 23. energy Radiant energy from the sun.
Down
- 1. A changes in position from one point to another point.
- 2. energy Types of energy that cannot be replaced after they have been used. Fossil fuels and nuclear energy are examples.
- 4. energy Energy formed by breaking bonds in a chemical reaction.
- 5. Composed of one type of atom that cannot be broken by ordinary means.
- 7. energy Generation of electricity using flow of water (usually from a dam) to drive a turbine that powers a generator.
- 8. Generated when wind turns turbines to run generators that convert energy into electricity.
- 9. energy Stored energy, the energy of position.
- 12. A viscous liquid from petroleum, especially for use as a fuel or lubricant; A liquid mixture of hydrocarbons present in rock that can be extracted and made into gasoline, kerosene, and oil.
- 15. energy Energy released during nuclear fission or fusion, especially when used to generate electricity.
- 16. fuels A fuel such as coal, oil, petroleum, or natural gas that is formed in the geological past from the remains of living organisms.
- 17. A fossil fuel created by pressure on decayed trees and plants from primeval forests.
- 20. transformation Energy cannot be created or destroyed, it can only change forms. Energy transformations start with the power source then change to other forms of energy.
- 21. The ability to do work.
