Across
- 4. A resource that can be replaced when needed.
- 5. Making better use of the available supplies of energy.
- 6. The energy associated with the flow of electrons.
- 10. Rain contaminated by the by-products of combustion, such as carbon dioxide (CO2), nitrous oxides (NOx), and sulfur oxides (SOx), which condense in our atmosphere.
- 12. Energy in motion.
- 13. A measure of the unavailable energy in a closed system.
- 19. The potential energy locked within a substance.
- 20. An increase in the average temperature of the earth’s atmosphere, possibly resulting in the melting of ice caps, which could alter shorelines, change weather patterns, and alter agricultural productivity.
- 21. The extent to which an energy form is usefully converted into another form of energy.
- 22. A resource that cannot be replaced once used.
Down
- 1. An energy source that will never run out.
- 2. a group of nations committed to the strength and success of the oil market. These countries export oil to consumer nations.
- 3. The use of energy resources.
- 7. Energy waiting to happen.
- 8. The situation caused by a layer of greenhouse gases surrounding our planet, produced by the burning of fossil fuels. This layer does not allow the heat produced by the sun to escape the earth’s atmosphere as easily as it once did.
- 9. A basic unit of measurement for heat energy. It is the amount of heat necessary to raise one pound of water one degree Farenheit.
- 11. Energy produced by mechanical devices, such as gears, pulleys, levers, or more complex devices, such as internal combustion engines.
- 14. The changing of one form of energy into another.
- 15. Restriction of trade for political means.
- 16. The power of the atom.
- 17. Energy visible to the eye.
- 18. Energy with a longer wavelength than light energy. It is generally not visible to the eye, but it can be measured in terms of temperature. Also referred to as infrared energy.
