Across
- 1. movement of water through a dam converted to usable energy
- 4. plant material or animal waste converted to usable energy
- 5. the Sun's energy converted to useable energy
- 8. the total kinetic energy of tiny particles of matter-the faster the particles move the warmer the matter becomes
- 9. heat from deep beneath earth's surface converted to useable energy
- 11. transfer of energy by the movement of electromagnetic waves or subatomic particles
- 13. gases such as CO2 in the atmosphere that absorb and retain heat
- 14. heat transfer caused by rising of hotter, less dense fluids and falling of cooler, more dense fluids
- 16. the splitting of uranium atoms to release energy
- 17. transfer of energy that occurs in solids, liquids and gases when two substances of different temperatures touch
- 18. material that does not conduct heat or electrical current
- 19. a supply of energy that can be used to generate power
Down
- 2. energy resource that is replaceable by nature
- 3. coal, oil and natural gas formed over a very long time from the remains of living organisms
- 6. circular movement of fluids caused by the rising of hotter, less dense fluid and the falling of cooler, more dense fluid
- 7. the change of energy from one form to another
- 10. produced when turbines harness the movement of air and convert it to energy
- 12. energy resource that takes millions of years to form
- 15. substance that readily transfers heat or electrical energy
