evaporation

EvaporationEvaporation 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

Condensation

Water vapor in the air gets cold and changes

back into liquid, forming clouds.

Precipitation

Precipitation occurs when so much water has condensed 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.Video
