GEOLOGY

Detailed explanation-1: -And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Another 30 percent of freshwater is in the ground. Fresh surface-water sources, such as rivers and lakes, only constitute about 22, 300 cubic miles (93, 100 cubic kilometers), which is about 1/150th of one percent of total water.

Detailed explanation-2: -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: -The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation. Humans can use both ground and surface water.

Detailed explanation-4: -About three-quarters of Earth’s freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!

Detailed explanation-5: -The oceans are, by far, the largest storehouse of water on earth-over 96% of all of Earth’s water exists in the oceans.
