Shields
Erosion of peneplains by glaciers in shield regions is limited. In the Fennoscandian Shield average glacier erosion during the Quaternary amounts to tens of meters, albeit this was not evenly distributed. For glacier erosion to be effective in shields a long "preparation period" of weathering under non-glacial conditions may be a requirement. The landforms and resulting from glaciation of northern shields result in different landforms sedimentary deposits than those found on shields closer to the equator.

The numerous lakes of the Canadian and Fennoscandian (Sweden and Finland) shields are thought to have originated at least partly from glacier's selective erosion of weathered bedrock.

Mountains
According to the glacial buzzsaw hypothesis erosion by warm-based glaciers is key to limit the height of mountains above certain threshold altitude.
