Precipitation
is very important as without adequate rainfall or snowfall, the earth
would become a vast desert. It
also cleans air of pollutants as small dust and dirt particles in the
atmosphere attach to the water droplets and are carried to the earth
when the rain or snow falls.
The
water on earth is continually being changed from one form to another.
This
change is the state of matter of water is called the Water Cycle.
There
are three steps to the water cycle:
1.
water in lakes
and oceans is heated by the sun’s energy and rise into the air (EVAPORATION)
2.
the water rises
high enough to freeze and form a cloud
(CONDENSATION)
3.
the water falls
from the cloud as rain, sleet, hail, or snow
(PRECIPITATION)
