Water Cycle

examines the movement of water across (and below and above) earth's surface. Among the topics: condensation, evaporation, freshwater storage, ground-water storage and discharge, infiltration, precipitation, snowmelt runoff to streams, springs, streamflow, surface runoff, transpiration, water in the atmosphere, ice and snow, and oceans. A diagram and text summarizing the water cycle are available in more than 30 languages. (U.S. Geological Survey)

Interesting Fact:

Almost 90 percent of earth's ice mass is in Antarctica, while the Greenland ice cap contains 10 percent. The Greenland ice cap became so large because more snow fell than melted. Over the millenia, as the snow got deeper, it compressed and became ice.
