The ice cap that covers Antarctica is more than 2100 meters thick in places, more than two kilometers (1.3 miles). This is where most of the world's fresh water is contained. If it melted completely it would raise sea levels by 61 meters (200 feet).

Its average thickness is about 1.6 km.

According to NASA the West Antarctic ice sheet rests on a bed well below sea level and is drained by much larger outlet glaciers and ice streams that accelerate over distances of hundreds of kilometers before reaching the ocean, often through large floating ice shelves. The deepest known ice rests 2,555 meters below sea level, where the ice is over 4 kilometers thick.

How thick are the ice caps in Greenland?

At its centre, the Greenland ice cap is over 3km thick (around 3275m). However, in the last ten years, the rate of reduction of Greenland's ice sheet has trebled. In the article published in the Jan 8th 2011 edition of New Scientist it was suggested that this icecap holds enough ice to raise (MORE)

How thick can Antarctica ice get?

The maximum thickness of ice in the Antarctic ice sheet is 15,670feet. It averages 7,300 feet on the eastern side and 4,285 feet onthe western side.

How much of Antarctica is covered in ice?

Antarctica is 5,400,000 sq miles (14,000,000 sq km) in size. Of this, 5,300,000 sq mi (13,720,000 sq kms) is ice covered, leaving 100,000 sq mi ( 280,000 sq km) ice free. This works out at 98.15% ice covered, 1.85% ice free.

What percentage of Antarctica is covered in ice and snow?

Antarctica is 5,400,000 sq miles (14,000,000 sq km) in size. Of this, 5,300,000 sq mi (13,720,000 sq kms) is ice covered, leaving 100,000 sq mi ( 280,000 sq km) ice free. This works out at 98.15% ice covered, 1.85% ice free. During the winter months, 100% of Antarctica is covered in ice. During (MORE)

Is Antarctica covered in ice?

Yes.. Antarctica is a continent of approximately 14,000,000 sq km.. The Antarctic Ice Sheet consists of about 13.72 million sq km of permanent ice up to over 4 km thick and representing 90% of the world's ice.

How thick is the sea ice in Antarctica?

The Antarctic continent nearly doubles in size every winter, because the sea freezes around the continent. At the beach, at McMurdo Station, for example, the ice is eight to 20 feet thick by the end of winter, based on the shape of the benthos under the ice. Ice tends to be thicker where the sea i (MORE)

What is Antarctica is covered by ice?

Because Antarctica is a "polar" region, there is no precipitation, it has no lakes or rivers and is in fact the driest continent.. Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months.. The coastal temp (MORE)

How thick is the Arctic ice cap?

The Arctic ice cap consists of sea ice and the Greenland ice sheet . Sea ice can be several meters thick, while the Greenland ice sheet is several thousand feet thick in the interior. Sea ice and ice sheets are two entirely separate things. The main being that ice sheets are formed from accumulat (MORE)

Name of the cracks in Antarctica ice cap?

Cracks in any ice cap are called crevasses , and because theyare subject to shifting and re-shaping, they are not generallynamed. Antarctica is covered in an ice sheet, and eruptions in that sheetare called nunataks -- mountain tops. Again, any crack inthe ice sheet would be a crevasse and would (MORE)

How much ice is at the antarctica ice cap?

The Antarctic ice sheet is the largest in the world with about 13.72 million sq km of permanent ice representing about 90% of the worlds ice and is over 4 km thick in places.

How is global warming affecting the ice caps in antarctica?

Antarctica has already been experiencing warming, though not as much as in some other parts of the world. It is generally losing ice, though mostly on the coast whereas there may be slight gains in East Antarctica. Sea ice has been slowly increasing in coverage, though this is largely due to variati (MORE)

How much ice covers Antarctica?

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

What is a thick sheet of ice covering a large area of land?

Also called ice sheets, they can be called glaciers or continental ice masses. While glaciers, by definition, have to be moving- albeit VERY slowly- ice sheets can just lay there until they move, which could classify them as a glacier.

How could the ice caps form in Antarctica if it is a desert?

That an area is a desert does not mean that it is hot, just thatthere is very little precipitation. Antarctica gets very littlesnow, but it is cold enough that what little snow falls nevermelts. It has been like this for millions of years, allowing thesnow to pile up and compress into ice sheets sev (MORE)

How much ice covers Antarctica surface?

The ice covers 13,720,000 km2 (5,300,000 sq mi) of Antarctica. This ice sheet contains over 5 million cubic miles (30 million cubic km) of ice. If it was broken up, every person on Earth would receive a piece the size of the Great Pyramid.

Why is Antarctica covered in ice and snow?

Antarctica used to be a tropical island, then the earth rotater over years and years has caused it to be in a colder climate. The wind blows constantly there which keeps it in a deep freeze. This came from a pamphlet about Antarctica that I read.

How thick is the icecap that covers Antarctica?

Over the South Pole, the ice is about 12,000 feet thick, and is one of the few places where estimated measurements have been made as to the thickness of the continental ice cap. About 4 miles!

What would happen if the west ice cap in Antarctica melted?

This is only a hypothetical, since it is generally agreed by eventhe most pessimistic scientists that this ice cap will not melt inour lifetimes. If it did happen, then sea levels would rise byseveral meters and we would have to abandon many of our coastalcities and productive coastal farmland. A mo (MORE)

How can there be rivers under the Antarctica Ice Caps?

Rivers on the surface of Antarctica are a seasonal melt-waterphenomenon near the coasts. Under the ice sheet, there aresub-glacial lakes, not rivers. Some theorize that the bottoms of the ice sheet melt due togeo-thermal heat.

Why are Antarctica ice caps melting?

Global warming. The warming oceans are actually melting the feet of the glacierswhere they move down onto the ocean floor. This creates ice shelvesresting on the top of the water. These shelves then break off toform icebergs, sometimes as big as the island of Manhattan. They aren't melting. In fac (MORE)

Why is Antarctica covered with thick ice if it only snows a few inches a year?

Antarctica's ice sheet has been building up for millennia; icecores documenting the Earth's atmosphere for the past 800,000 yearshave been drilled in it. The ice sheet is formed from moisture -- what little there is givenan average of five percent humidity on the continent -- thatfreezes. Snow is i (MORE)

How thick is the Greenland ice cap?

The Greenland ice sheet is a vast body of ice covering 1,710,000square kilometres and its thickness is generally more than 2 km andover 3 km at its thickest point.
