Water consists of two hydrogen atom and one oxygen atom
(H2O). Water covers three-fourths of the Earth's surface,
60-70% of the world's weight, regenerates and redistributes through
evaporation and other atmospheric processes. Water is involved in
electrical charge separation because it has two types and positions of
atoms giving it a net dipole movement. Water vapor also absorbs 17% of
solar radiation in the troposphere, thus making it one of the two
principal greenhouse gases. Of the solar energy absorbed by the Earth's
surface a little more than half goes into latent heat, which is heat
absorbed by water because of its transformation from a liquid to a gas.
When these molecules condense back into a liquid, usually higher in the
atmosphere, they released that energy back into the atmosphere as local
warming.
