Atmospheric Moisture Introduction Water is an essential ingredient for life to exist on earth. Water vapor is highly variable in the atmosphere,  ranging from .2 percent in cold dry climates to as such as 5 percent in the humid tropics. These numbers seem  small but for every minute of the day nearly 1 billion tons of water is given up to the atmosphere. 80 percent of  the water present in the atmosphere comes from evaporation from oceans. The geography of water plays a  crucial role in shaping the earth, the distribution of soils, vegetation, and animals. In this lecture we'll look at the  phase changes that water goes through, the products of condensation, and major cloud types.
