Water cycle

The Earth has a limited amount of water.That water keeps going around and around and around and around and (well ,you get the idea) in what we call the water Cycle.”

This cycle is made up of a few main parts.

>Evaporation (and transpiration)

>Condensation

>Precipitation

>Collection

EVAPORATION””

       Evaporation is when the sun heats up water in river or lakes of the ocean and turns into vapor or steam.The water vapor or steam leaves the river,lake or ocean and good into the air .

TRANSPIRATION”’

     Transpiration is the process by which plants lose water out of their leaves.transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.

A-Evaporation                          C-Precipitation

B-Condensation                       D-Collection

CONDENSAThION’

           Water vapor in the air gets cold and changes back into liquid ,Forming clouds .This is called condensation.

You can see the same sort of thing at home…..

1.Pour a glass of cold water on a hot day and watch what happens.

2.Water forms on the out of the glass .That water didn’t somehow leak through the glass! It actually came from the air.

3.Water vapor in the warm air ,turn back into liquid when it touches the cold.

PRECIPITATION.

      Precipitation occurs when so much water has condensed that the air cannot hold it any more.The clouds get heavy and heavy falls back to the earth in the form of rain hail,sleets and snow.

COLLECTION

When water falls back to earth as precipitation .It may fall back in the oceans,Lakers or rivers or it may end up on land.When  it ends up on land .it will either soak into the earth or become part of the ”ground water” that  plants and animals use to drink or it may run over the soil and collect in the oceans ,lakes or rivers where the cycle starts.
