    The lowest layer of the atmosphere, in which the temperature decreases at a constant rate as altitude increases.
  4. Define Stratosphere
    The layer of the atmosphere that is above the troposphere and which temperature increases with the altitude.
  5. Define Mesosphere
    The layer of the atmosphere between the stratosphere and the thermosphere and the temperature decreases as altitude increases.

  12. Define wind
    The movement of air caused by differences in air pressure.
  13. Define Coriolis effect
    The apparent curving of the path of an object from an otherwise straight path because of the earth's rotation

  17. Define Jet streams
    A narrow belt of strong winds that blow in the upper troposphere
  18. Define Air Pollution
    The contamination of the atmosphere by the introduction of pollants from human and natural sources
