GEOLOGY

Detailed explanation-1: -This much amount of freshwater is locked in glaciers and is not available for use. Antarctica and Greenland have most of the glaciers. Additional information: Some amount of freshwater that is about 30 percent is present below ground as soil moisture and is not accessible.

Detailed explanation-2: -And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Another 30 percent of freshwater is in the ground. Fresh surface-water sources, such as rivers and lakes, only constitute about 22, 300 cubic miles (93, 100 cubic kilometers), which is about 1/150th of one percent of total water.

Detailed explanation-3: -Ice caps and global water distribution As these charts and the data table show, the amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth, but the majority of total freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers.

Detailed explanation-4: -Most U.S. glaciers are in Alaska; others can be found in Washington, Oregon, California, Montana, Wyoming, Colorado, and Nevada (Wheeler Peak Glacier in Great Basin National Park).

Detailed explanation-5: -4. 2.0% of freshwater is found in ice caps and glaciers, 0.75% of freshwater is in the ground as groundwater, 0.009% in freshwater lakes, 0.001% in the atmosphere, 0.0001% in the rivers. 5. Nowadays, groundwater is used as the main source of water in major cities.
