Antarctica's ice sheet rests on 98% of the continent. It has been said that the ice is so heavy, ". . . In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2,500 m below sea level." Quoted from the Antarctic Ice Sheet entry in Wikipedia.
This is some, not most of the ice sheet.
Ice shelves exist mostly below sea level.
Some of Antarctica is below sea level, notably the continent beneath the South Pole. The ice is nearly two miles thick and the base of the ice could be below sea level.
Most of the continent is above sea level. However, under the polar ice sheet there is land that is below sea level.
Antarctica is not below sea level. It is a continent mostly covered by thick ice sheets, with its surface elevation reaching heights of over 4,000 meters above sea level.
It is generally assumed that Antarctica has no surface locations below sea level. This is because any area that is below sea level has been filled in and covered by ice. However, there is a coastal area of the rocky Vestfold Hills in coastal Antarctica which has valleys below sea level, as low as -50 meters (150 feet). (These mountains are south of the Indian Ocean, due south of westernmost India.)
In Antarctica an ice sheet covers 98% of the rocky continent below.
This area is the Antarctic Peninsula. You can read about its climate, below.
The continent with the highest average altitude is Antarctica, while the continent with the lowest point below sea level is Antarctica as well, with parts of the East Antarctic Ice Sheet being below sea level.
The Bentley Subglacial Trench, which reaches a depth of 2,555 meters below sea level is the lowest point in Antarctica. It is also the lowest place on earth not covered by ocean but by ice.
Most of Antarctica is high above sea level, making it the highest continent on Earth. Most all of the area is mountainous and 98% of it lies under an ice sheet.
A few of Antarctica's ice shelfs are as named below: Ross ice shelf Ronne/Filchner ice shelf Riiser-Larson ice shelf Larsen ice shelf
ice crystals form the most common precipitation in Antarctica, most of which evaporates before settling on the ice cap.
Most of the world's ice is located in Antarctica. This vast continent holds about 70% of the fresh water on Earth in the form of ice.
