Question

which part of Greenland is under parmanent ice
​

Answer 1

Answer:

A warm-based glacier or ice sheet will have liquid water at its base. Water and ice together are highly erosive, and the combination often scours landscapes. A cold-based ice sheet, however, will simply freeze to the bed, preserving whatever lies under the ice, even as the upper layers of ice flow over it.

Answer 2

Answer

The oldest known ice in the current ice sheet is as much as 1,000,000 years old. The weight of the ice has depressed the central area of Greenland; the bedrock surface is near sea level over most of the interior of Greenland, but mountains occur around the periphery, confining the sheet along its margins.
