Detailed explanation-1: -Complete answer: Earth has about 97 percent of the water that is present in oceans and it has about three percent of the freshwater present in glaciers, ice caps, below ground, and rivers. Most of the freshwater that is not present below ground or in rivers is locked in the ice glaciers that is about 69 percent.

Detailed explanation-2: -According to the U.S. Geological Survey, most of that three percent is inaccessible. 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-3: -Of all the water that exists on our planet, roughly 97% is saltwater and less than 3% is freshwater. Most of Earth’s freshwater is frozen in glaciers, ice caps, or is deep underground in aquifers.

Detailed explanation-4: -Only a little over 3% of Earth’s water is fresh. Most of that fresh water (68.7%) is frozen in glaciers and ice caps. 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-5: -The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes.
