Landforms of glacial erosion

Abstract

Glacial erosion occurs most prominently in association with warm-based ice that is not frozen to its bed and in abundant association with meltwaters. Glacial erosion is accomplished primarily by subglacial abrasion from other rock fragments entrained in the moving ice, as well as by plucking in which basal meltwater refreezes beneath the ice to pull off blocks of bedrock. A wide variety of small-scale and large landforms are produced in the bedrock.
