Evaporation
Evaporation is the main mechanism for moving water back into the atmosphere. When water absorbs enough energy it will change from a liquid state to a gaseous state. This is done by turning water into water vapor. The oceans are the source of about 86% of evaporation. The over 14% occurs on land. This is due to the fact that the sun's energy is captured by the vast expanses of the oceans.
