HYDROLOGIC CYCLE

Movement or exchange of water between the atmosphere and earth.

The process of evaporation, vertical and horizontal transport of vapor, condensation, precipitation, and the flow of water from continents to oceans. It is a major factor in determining climate through its influence on surface vegetation, the clouds, snow and ice, and soil moisture. The hydrologic cycle is responsible for 25 to 30 percent of the mid-latitudes' heat transport from the equatorial to polar regions.

The cycle through which water passes from the oceans through the atmosphere to the land and back to the oceans.
