Water
Cycle:
Evaporation is
the physical process of a liquid or solid changing over to a gaseous
state. The energy released from the earth's sun causes the water molecules
to speed up and change from a liquid state to a gaseous state. Evapotranspiration is when this process occurs through plants.
In
the video to the left the sun is the driving force behind evapotranspiration
and evaporation. Water is converted from a solid or liquid
to a gas.
Note that once water vapor rises to a certain height condensation
begins as see by clouds.
