Detailed explanation-1: -The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles), with 97.5% being salt water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface.
Detailed explanation-2: -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-3: -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. There are two kinds of ice on Earth’s surface, sea ice and land ice.
Detailed explanation-4: -The amount of world’s freshwater in polar ice caps and glaciers is 70%.
