  2. precipitation - rain freezes on its way to the ground
    sleet
  3. layer of atmosphere closest to Earth's surface (weather occurs there)
    Troposphere  (tornado is weather)
  4. precipitation made in clouds by water vapor freezing into ice crystals
    snow
  5. cloud that brings thunderstorms
    cumulonimbus
  6. high, thin, feathery cloud during fair weather
    cirrus
  7. object forms his in sky when water vapor begins to condense
    cloud
  8. cloud that is low and fluffy  brings fair weather
    cumulus
  9. cloud that is low and layered and brings rain
    stratus
  10. part of atmosphere above the weather, jet planes fly there and it protects from the Sun's ray.

  11. atmosphere part closest to space
    thermosphere
  12. type of water that falls from the clouds to the Earth's surface
    precipitation
  13. layer of atmosphere that helps protect us from meteors
    mesosphere (meteors)
  14. precipitation that is liquid water
    rain
  15. precipitation that is drops of rain in clouds that freeze, then blows upwards until to heavy and then fall to the Earth
