The ice sheet that covers the Antarctic continent is all fresh water. According to its Wikipedia entry:
"It covers an area of almost 14 million square km (5.4 million sq. miles) and contains 26.5 million cubic km of ice (6.36 million cubic miles)."
The estimate is that this amount of fresh water is about 70% of the total available on earth.
The same as normal water. 7.
about 2% of the worlds fresh water are locked up in the polar ice caps....
About 3% of the water on Earth is fresh. Only about .1% of the fresh water is visible on land. About 75% of the fresh water is locked in glaciers and ice caps. Then about 24.9% of the fresh water is underground.
Glaciers. Or frozen ice caps.
About 70% of Earth's fresh water is found in glaciers and icecaps
Its renewable because the ecosystem collects and purifies the fresh water. Its limited because the earth is only made up of 3% of fresh water and most of the other half is locked up in ice at the Poles.
only 3% is fresh water
We can't use all of the Earth's fresh water, because much is locked away as ice, notably at the Arctic and Antarctic regions, and in the many glaciers in certain mountain ranges.
Only about 3% of Earth's water is fresh, and of that, 2/3 is locked up (albeit temporarily) in ice sheets and the polar ice caps. The remainder is salt water. So roughly 1% of the fresh water is readily available, though perhaps inaccessible in lakes etc.
Mostly at the North and South poles or rather, the Arctic and Antarctic. 90% of the world's fresh water is locked up in ice at the Antarctic.
Most of Earth's fresh water is locked up in glaciers. "Supply" would reference rivers and lakes.
About 3 percent (2.75%) of the total water on Earth is fresh water, and as much as 75% of that is locked up as ice in glaciers and polar caps. Most of the rest is ground water. The water vapor in the air constitutes 4 times as much water as all of the surface freshwater on the planet (0.04 % vs 0.01 %).
