Icebergs calving off the Antarctic ice sheet is a normal phenomenon that has occurred for eons and will continue to occur. The weight of ice on the continent forms glaciers that push the ice sheets out over the ocean.
In recent years warming waters are undermining the ice shelves at the point where they reach the sea. This is known as basal melting.

What percentage sheet of ice does the Antarctica Ice sheet hold?
The ice sheet holds 100% of Antarctica's . . . ice sheet.
What are the rivers of ice in antarctica called?
i think the rivers of ice in Antarctica are called glaciers.
What are the ice free reagions of Antarctica called?
Ice-free regions in Antarctica are generally called 'the beach'.
Is the ice on Antarctica salt water?
Nope...lots of land, even unfrozen lakes, under the ice. Basically, Antarctica is a small continent (say the size of Australia) covered by a sheet of ice...and now it's shrinking. no, underneath the ice is rocky land Edited by Danielle Robertson 5/3/2009 :P
Why do ice freeze in cracks?
Ice can freeze in cracks due to a combination of lower temperatures and the presence of water. When the temperature drops, the water that seeps into these cracks can freeze, expanding as it does so. This expansion can further widen the cracks, allowing more water to enter and freeze, creating a cycle that enhances the formation of ice. Additionally, the insulating properties of ice can help maintain lower temperatures within the cracks, promoting further freezing.
What are the cracks in antarctica called?
Cracks in the ice sheet, which covers 98% of the continent, are called crevasses.
What are cracks in the ground in Antarctica called?
Since 98% of the continent is covered by an ice sheet, it is difficult to see 'cracks in the ground' in Antarctica. Otherwise, these would be known as canyons.
Where do antarctic seals live?
Antarctic seals primarily live along the coast of Antarctica and on surrounding ice floes. They rely on the sea ice for breeding, molting, and resting, as well as for finding food through cracks in the ice.
Name of the cracks in Antarctica ice cap?
Cracks in any ice cap are called crevasses, and because they are subject to shifting and re-shaping, they are not generally named.Antarctica is covered in an ice sheet, and eruptions in that sheet are called nunataks -- mountain tops. Again, any crack in the ice sheet would be a crevasse and would exist without a name.
What percentage of the ice can find in the antarctica?

What is the percentage of the ice in Antarctica?
One hundred percent of the ice in Antarctica is ice.
Is the ice sheet on Antarctica shrinking?
yes ice in the antarctica shrink
What percent of the world's ice is in Antarctica?
Antarctica's ice sheet represents about 90% of the earth's ice.
