Comments: Precipitation washes the environment. Consider how valuable
this process is. Each drop of precipitation forms around a speck
of dirt in the air. The air in cleansed in this process.
The earth is cleaned of dust, dirt, spit,insecticides, winter
road salt, used oil, broken down trees, and pollution of all
manner.
When evaporation occurs, only the pure water is evaporated. The
rest of the runoff is left behind--eventually in the oceans.
Isn't that frightening?
