Water Cycle

• The Water Cycle (also known as the hydrologic
  cycle) is the journey water takes as it
  circulates from the land to the sky and back
  again.
• The Sun's heat provides energy to evaporate water
  from the Earth's surface (oceans, lakes, etc.).
  Plants also lose water to the air
  (transpiration). The water vapor eventually
  condenses, forming tiny droplets in clouds. When
  the clouds meet cool air over land, precipitation
  (rain, sleet, or snow) is triggered, and water
  returns to the land (or sea). Some of the
  precipitation soaks into the ground. Some of the
  underground water is trapped between rock or clay
  layers this is called groundwater. But most of
  the water flows downhill as runoff (above ground
  or underground), eventually returning to the seas
  as slightly salty water.
