What land form is created when glaciers erode backwards into the mountainside and form a shape like a shallow bowl?

corrie



Corries or Cirques

A corrie (also called a cirque or cwm) starts as a snow patch on a cold mountain side. This causes a deepening of the hollow in which the snow has accumulated, a steepening of the walls behind and to its sides, and an ‘armchair’ shaped features is gradually produced.




Above the surface freeze-thaw will be an important process. It weakens and dislodges rock material from the corrie walls, helping to steepen them and cut them backwards into the mountain side.




Cirques:
a half-open steep-sided hollow at the head of a valley or on a mountainside, formed by glacial erosion.
A bowl-shaped depression carved out of a mountain by an alpine glacier.
