How much of the worlds water is held in antarctica?

Answer 1

The Earth total water volume is roughly 1.3 billion cubic kilometres (Volume of all of the oceans), while the volume of water locked in Antarctica is roughly 30 million cubic kilometres. This works out to be about 2.3%;

(3.0x107 / (3.0x107+1.3x109)) x 100

Another way is to consider that Antarctica holds 70% of the worlds freshwater, where freshwater as a whole makes up 3% of the words water. 70% of 3% = roughly 2.1%

Answer 2

I cannot help you out with the water estimate, but - The Antarctic Ice Sheet consists of about 13.72 million sq km of permanent ice representing 90% of the world's ice.

Answer 3

The Antarctic Ice Sheet consists of about 13.72 million sq km of permanent ice representing 90% of the world's ice.

Answer 5

According to Wikipedia, this number is about 61%.

Answer 6
