What is glacier landform?

Glacier landform is formed by glacial action which is divided into glacial erosion landform and glacial deposition landform.

Glacial erosion landform: Glacial erosion landform is formed after glacier erosion action. Glacier erosion action refers to the destructive effect of glacier and rock fragment carried by glacier on glacial bedrock which is generally divided into plucking action and abrasive action. Glacial erosion landform is generally in the upstream of glacier, namely the place above the snow line in the forms of horn, knife-edge crest, cirque, cross wall, glacial valley, roche moutonnee, glacier groove and other abrasion landforms.

Glacial deposition landform: Glacial deposition landform is mainly divided into terminal moraine, lateral moraine, hillock moraine, trough moraine, drumlin, esker, kame, icy water washed plain and fluvioglacial terraces.
