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.
None. Antarctica is a continent, 98% of which is covered by ice.
70 % is water and 90% is ice
Antarctica's fresh water cache is about 70% of all the fresh water on earth -- frozen in its ice sheet that covers 98% of the continent.
Antarctica's ice sheet contains about 70% of the earth's fresh water.
There isn't much drinking water because almost all of the water is frozen. The snow can be thawed to give fresh water. The rainfall in Antarctica is very low.
Seventy one percent of earth's surface is water -- salt water. The ice sheet in Antarctica holds about seventy percent of earth's fresh water.
It is estimated that about 70% of the earth's fresh water is frozen in Antarctica's ice sheet.
If you are in the water in Antarctica, generally, you'd step onto the beach to get out of the water.
Believe it or not, with all of that frozen water around, Antarctica is considered to be desert.
Antarctica receives little rainfall in 1 year. About 35-50 centimeters of water is received in Antarctica. It may sound strange, but Antarctica is also considered a desert, a landscape/ region that receives little or no precipitation.
Antarctica isn't known for having any problems with water.
The number you want is about 70%.
