GEOLOGY

Detailed explanation-1: -Water covers about 71% of the earth’s surface. 97% of the earth’s water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling). 3% of the earth’s water is fresh.

Detailed explanation-2: -Fresh water makes up under 3% of all water on earth, and nearly 65% of this drinkable water is tied up in glaciers. Rivers, streams, lakes, and dams that hold freshwater contain 1% of potable water while groundwater accounts for 0.3%.

Detailed explanation-3: -In the first bar, notice how only 2.5% of Earth’s water is freshwater-the amount needed for life to survive.

Detailed explanation-4: -Our freshwater is locked up in the Antarctic Ice Sheet. About 71% of the Earth is covered in water. Most of that is in oceans, rivers, and lakes, but some is frozen in the Earth’s two ice sheets.

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.
