Across
- 2. Plant materials and animal waste used especially as a source of fuel.
- 5. A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity.
- 10. A device that converts light into electricity.
- 11. Energy The energy possessed by a body as a result of its motion.
- 13. A resource that cannot be replaced once used.
- 14. Energy An energy source that will never run out.
- 17. Energy associated with the flow of electrons.
- 18. The rate at which work is performed or energy is expended.
- 20. The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
- 21. Gas usually found within the vicinity of petroleum reserves.
- 28. The power of the atom.
- 29. A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.
- 32. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
- 34. stored in the earth in the form of heat.
- 36. The use of flowing water from waterfalls and dams to produce electricity.
- 37. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
- 38. The heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit at a constant pressure of one atmosphere.
- 39. The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
Down
- 1. A system by which electrical power is delivered throughout a region.
- 3. The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface.
- 4. Oil.
- 6. Energy can be neither created nor destroyed. There is a fixed amount of energy present in different forms that can be converted from one form to another, but energy does not go away.
- 7. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
- 8. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.
- 9. A result of a force moving an object a certain distance.
- 12. A measure of power equal to one joule of work per second.
- 15. The potential energy locked within a system and released during a chemical reaction.
- 16. surroundings.
- 19. Energy derived from wind by means of windmills or wind turbines.
- 20. Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
- 22. A resource that can be replaced when needed.
- 23. Energy from the sun.
- 24. Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines.
- 25. The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
- 26. A unit measure of work.
- 27. A collection of wind turbines used to create electricity.
- 30. The flow of electrical power or charge.
- 31. Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer.
- 33. Energy visible to the eye.
- 35. Energy in transit.
