What is the Water Cycle?

• The Water Cycle describes the existence and
  movement of water on, in, and above the Earth.

The Stages of the Water Cycle

• The first stage is Precipitation. This occurs
  when so much water has collected that the air
  cannot hold it anymore.  The clouds get heavy and
  water falls back to the earth in the form of
  rain, hail, sleet or snow.
• The second stage is Collection. When water falls
  back to earth as precipitation, it may fall back
  in the oceans, lakes or rivers or it may end up
  on land. 
• The third stage is Evaporation. Evaporation is
  when the sun heats up water in rivers or lakes or
  the ocean and turns it into vapor or steam. The
  water vapor or steam leaves the river, lake or
  ocean and goes into the air.
• The fourth stage is Condensation. Water vapor in
  the air gets cold and changes back into liquid,
  forming clouds. This is called condensation.
