    troposphere
  2. the highest layer of the atmosphere
    thermosphere
  3. layer of the atmosphere where gases do not mix
    stratosphere
  4. middle layer of the atmosphere, the coldest layer
    mesosphere
  5. a vehicle that runs on both electricity and gasoline is called a
    hybrid car
  6. What is the greatest problem created by the ozone hole
    It allows more UV rays to reach the Earth's surface
  7. What is the largest source of human-caused air pollution in the U.S.?
    vehicle exhause
  8. Which is an example of a primary pollutant?
    sea salt
  9. what causes local winds?
    temperature differences
  10. The winds that blow from the poles to 60 degree latitude in both hemispheres are called
    polar easterlies
  11. the winds that blow from 30 degrees to 60 degrees latitude in both hemispheres are called
    westerlies
  12. the winds that blow from 30 degrees latitude in both hemispheres toward the equator are called
    trade winds
  13. wind occurs because of differences in
    air pressure
  14. global warming may be caused by
    an increase in greenhouse gases
  15. convection is the transfer of energy
    by circulation of gases or liquids

    as electromagnetic waves
  18. most solar energy that reaches Earth's atmosphere is
    absorbed by the Earth's surface
  19. The protective ozone layer is found in the
    stratosphere
  20. air temperature changes as altitude increases because of
    gases that absorb solar energy
  21. Why is air pressure greatest at the Earth's surface?
    because gravity pulls gas molecules toward the surface
  22. About how much of Earth's atmosphere is oxygen?
    21%
  23. The air we breathe is mostly
