GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

Detailed explanation-3: -It is unexpected and somewhat inconceivable that less than three percent of Earth’s water is fresh water. 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.

Detailed explanation-4: -About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water.

Detailed explanation-5: -On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground-as groundwater, in wells and aquifers. Water vapor is most visible as clouds and fog. The frozen part of Earth’s hydrosphere is made of ice: glaciers, ice caps and icebergs.
