More than 70% of world's fresh water is contained in -Only about 2.5 to 3 percent of the water on earth is fresh water; the rest is salt water in the oceans.
Most of this fresh water is not in liquid form: about 70 percent of it is locked up as ice in the polar ice caps and ice sheets (Antarctica and Greenland).
Most of the remainder is ground water, and only a very small fraction is present in lakes and rivers.
Antarctica and Greenland are both parts of the polar ice, so the complete answer is polar ice.
So more than 70 percent of the world's fresh water is contained in polar ice.
