Across
- 7. The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
- 11. Fuel A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.
- 13. Turbine A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity.
- 14. A result of a force moving an object a certain distance.
- 15. Energy Energy from the sun.
- 16. The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
- 18. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
- 20. Energy The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
- 21. Energy The power of the atom.
- 22. Change Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer.
- 23. Energy Energy associated with the flow of electrons.
- 26. Plant materials and animal waste used especially as a source of fuel
- 27. Energy A resource that cannot be replaced once used.
- 30. Energy Energy in transit.
- 31. Grid A system by which electrical power is delivered throughout a region.
- 34. The flow of electrical power or charge.
- 35. Effect 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.
- 36. The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
- 37. A measure of power equal to one joule of work per second.
Down
- 1. Energy The energy possessed by a body as a result of its motion.
- 2. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.
- 3. Cell A device that converts light into electricity.
- 4. Energy An energy source that will never run out.
- 5. Gas Gas usually found within the vicinity of petroleum reserves.
- 6. Energy The potential energy locked within a system and released during a chemical reaction.
- 8. Thermal Unit 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.
- 9. Energy The use of flowing water from waterfalls and dams to produce electricity.
- 10. of Conservation of Energy 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.
- 12. Energy Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines.
- 17. Energy Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
- 19. A unit measure of work.
- 24. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
- 25. (Radiant) Energy Energy visible to the eye.
- 28. External surroundings.
- 29. Oil.
- 32. Energy stored in the earth in the form of heat.
- 33. Energy A resource that can be replaced when needed.
