Across
  1. 3. the transfer of thermal energy by the movement of heated material from one place to another
  2. 6. a small particle in the atmosphere around which water droplets can form
  3. 8. a type of cloud that is layered and sheetlike and can cover much or all of the sky in a given area; also occur below 2000 m
  4. 12. a type of cloud that has a wispy, indistinct appearance that forms above 6000 m
  5. 14. the layer located between approximately 85 km and 600 km above Earth's surface; this layer is hotter than the others because it absorbs most of the high-energy radiation
  6. 15. an increase in temperature with height in an atmospheric layer
  7. 18. occurs when cloud droplets collide and join together to form a larger droplet
  8. 20. occurs when an air mass is forced to rise over a topographic barrier
  9. 21. the natural heating of Earth's surface caused by certain atmospheric gases called greenhouse gases, including water vapor, methane, and carbon dioxide
  10. 22. the layer above the stratosphere in which air temperature decreases with altitude
Down
  1. 1. all forms of water that fall from clouds to the ground
  2. 2. the layer closest to Earth's surface that contains most of the mass of the atmosphere
  3. 4. the temperature to which air must be cooled at constant pressure to reach saturation
  4. 5. the layer above the troposphere that contains the ozone layer and in which the air temperature mainly increases with altitude
  5. 7. the transfer of thermal energy between objects when their atoms or molecules collide
  6. 9. occurs when the amount of water vapor in a volume of air has reached the maximum amount
  7. 10. the amount of water vapor in the atmosphere at a given location on Earth's surface
  8. 11. a type of cloud that is puffy and lumpy-looking that usually occurs below 2000 m
  9. 13. the outermost layer of Earth's atmosphere; the transitional area between Earth's atmosphere and outer space
  10. 16. the transfer of thermal energy by electromagnetic waves
  11. 17. the amount of water vapor in a volume of air relative to the amount of water vapor needed for that volume of air to reach saturation
  12. 19. extra thermal energy contained in water vapor compared to liquid water
