Only about 3% of Earth’s water is fresh water. Of this 3% most of it cannot be used by humans because it is found in ____
A
lakes
B
the atmosphere
C
glaciers
D
the oceans
Explanation: 

Detailed explanation-1: -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-2: -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. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.

Detailed explanation-3: -3% of the earth’s water is fresh. 2.5% of the earth’s fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth’s surface to be extracted at an affordable cost. 0.5% of the earth’s water is available fresh water.

Detailed explanation-4: -Most of Earth’s fresh water is locked in ice 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.
