Across
  1. 3. Change Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer.
  2. 6. 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.
  3. 7. Energy The potential energy locked within a system and released during a chemical reaction.
  4. 10. Energy A resource that can be replaced when needed.
  5. 13. The flow of electrical power or charge.
  6. 15. External surroundings.
  7. 16. Energy Energy from the sun.
  8. 23. Energy The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
  9. 24. A measure of power equal to one joule of work per second.
  10. 25. Energy The use of flowing water from waterfalls and dams to produce electricity.
  11. 28. Energy The power of the atom.
  12. 29. The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
  13. 30. Energy Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines.
  14. 31. Energy An energy source that will never run out.
  15. 32. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
  16. 33. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.
  17. 35. (Thermal) Energy Energy in transit.

  1. 1. Gas Gas usually found within the vicinity of petroleum reserves.
  2. 2. Energy The energy possessed by a body as a result of its motion.
  3. 4. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
  4. 5. Turbine A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity.
  5. 8. Energy Energy associated with the flow of electrons.
  6. 9. Grid A system by which electrical power is delivered throughout a region.
  7. 11. (Radiant) Energy Energy visible to the eye.
  8. 12. A unit measure of work.
  9. 14. Fuel A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.
  10. 15. Energy Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
  11. 17. 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. 18. Plant materials and animal waste used especially as a source of fuel.
  13. 19. Oil Photovoltaic Cell
  14. 20. 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.
  15. 21. Energy A resource that cannot be replaced once used.
  16. 22. Energy stored in the earth in the form of heat.
  17. 26. The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
  18. 27. A result of a force moving an object a certain distance.
  19. 34. The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
