Detailed explanation-1: -Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.

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: -Most of Earth’s fresh water is locked in ice Two ice sheets, the Antarctica Ice Sheet and the Greenland Ice Sheet, contain more than 99% of the ice on Earth’s surface.

Detailed explanation-4: -The solid form of water – ice is found at the poles of the earth, the snow covered mountains and the glaciers. The liquid form is present in the rivers, lakes, seas, and oceans.

Detailed explanation-5: -Fresh Water Around the World The Antarctic ice sheet holds about 90 percent of the fresh water that exists on the Earth’s surface. The ice sheet covers approximately 8.7 million square miles.
