a buried erosional surface is called unconformity.
surface effected by erosion
Moving water is the main erosional agent on the surface of the Earth.
A surface between successive strata representing a missing interval in the geologic record of time, and produced either by an interruption in deposition or by the erosion of depositionally continuous strata followed by renewed deposition.

An Unconformity is an erosional or non-depositional surface that separates rocks of two different ages. This is represented by missing sediments in the stratigraphic column. If the time period represented by the missing sediments is small, the unconformity is called a diastem.

Erosional plains are developments on the Earth's surface caused by natural weathering of glacier activity, wind movement or water (sea, river & stream) torrent and are subdivided on the basis of the type of erosional agent.
The movement within the Earth that causes buried rock to be exposed at the Earth's surface is called uplift. It refers to the vertical elevation of the Earth's surface.
