 | | Glaciers hold 69 percent of the freshwater, 1 percent is in lakes and rivers, and 30 percent is in ground water (Dingman, 1994). |
 | | The hydrosphere interacts with the atmosphere, geosphere, and biosphere through these pools following a complex and cyclic path commonly known as the Hydrologic Cycle. |
 | | The hydrosphere interacts with the atmosphere, geosphere, and biosphere through some of these pools and fluxes among the pools and spheres take place through precipitation, evaporation, condensation, transpiration, interception, infiltration, percolation, advective flow, overland flow, and channel flow. |
