Antarctica is the only continent with no permanent human habitation. There are, however, permanent human settlements, where scientists and support staff live for part of the year on a rotating basis. The continent of Antarctica makes up most of the Antarctic region.
The base level is the lower limit of the erosional process and the ultimate base level is the plains that result from the projection of sea level under the landmass. This process of erosion creates a peneplain.
The base level is dynamic and changes according to the following factors as sea-level changes, tectonic factors, river captures, and sedimentation.
Peneplinasare low featureless deposits that are created by the terminus of the dream where the sediments are merged with the sea.
