Detailed explanation-1: -97% of water on earth is in oceans, which is salt water. Only 3% of water present on earth is freshwater, out of which 2% is frozen in the form of ice caps and glaciers.

Detailed explanation-2: -b. 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-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: -Only about three percent of Earth’s water is freshwater. Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground. Most of our drinking water comes from rivers and streams.

Detailed explanation-5: -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.
