Water Cycle


Water, Water, Everywhere!

  • Water is the most important resource we have.

  • It is the most abundant resource!

  • The amount of water on Earth now is the same as it was millions of years ago!!

  • Water is not created or destroyed, it cycles through.


Moving Along…

  • Water moves in a cycle.

  • It changes states.

  • It moves in the troposphere and the surface of the Earth.


Evaporation/Transpiration

  • Water gets into the atmosphere through evaporation.

  • Plants also release water vapor; this is called Transpiration.


Condensation

  • Water vapor turns into very tiny water droplets.

  • The droplets combine and form clouds.


  • Dew- forms when water vapor droplets gather on a hard surface.

  • Frost- forms when water vapor droplets freeze onto a surface.


Precipitation

  • After the cloud forms, the water falls back to earth.

  • The temperature of the sky and clouds determines what type of precipitation falls.

    • Rain

    • Sleet

    • Snow

    • Hail

    • Freezing Rain


Surface and Groundwater Flow

  • When precipitation falls to the surface, it tries to flow back to sea level.

    • If water falls too fast, it stays where it is until the ground absorbs it. (Surface water)

    • Water will sink into the ground and become groundwater.
