How much water is on Antarctica?

Answer 1

None. Antarctica is a continent of approximately 14,000,000 sq km.

Because Antarctica is a "polar" region, there is no precipitation, it has no lakes or rivers and is in fact the driest continent. The interior of Antarctica is considered the world's driest desert because the extreme cold freezes water vapour out of the air.

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

I need to add to the above answer:

The answer to this question - "none" - is absolutely incorrect. While it is true that Antarctica is a cold, polar desert, it is covered in ice - hence water. Antarctica's ice sheets contain 70% of the world's fresh water. There are lakes, and streams in Antarctica as well. Some lakes are subglacial - beneath the ice sheet - including Lake Vostok, which is over 2,000 feet deep in places, and covers an area of 6,000 square miles. There are other, smaller lakes, some of them in the Dry Valleys (an ice-free portion of Antarctica), which maintain liquid water columns year round and are covered with only a few meters of ice. The Onyx River flows in the Dry Valleys during the summer, is 25 miles long, and has several tributaries. The above answer is correct in saying that there is very little precipitation - generally only a few centimeters per year.

Answer 2

The ice sheet that covers 98% of the continent contains about 70% of the earth's fresh water.

Answer 3

The ice sheet that covers 98% of the Antarctic continent contains about 90% of the earth's ice and about 70% of the earth's fresh water.

Answer 4

The ice sheet chat covers 98% of the Antarctic continent holds about 70% of the earth's fresh water.

Answer 5

The ice sheet covering 98% of the Antarctic continent holds about 70% of the earth's fresh water.

Answer 6

The ice sheet that covers Antarctica contains about 70% of the Earth's fresh water.
