Glaciers erode predominantly by three different processes: abrasion/scouring, plucking, and ice thrusting. 33) A ________ is an erosional feature specifically produced by alpine glaciation. Quarrying involves two separate processes: the fracturing or crushing of bedrock beneath the glacier, and the entrainment of this fractured or crushed rock. Glacial abrasion is the surface wear achieved by individual clasts contained within ice or by subglacial sediment sliding over bedrock (Cuffey and Alley, 1996; Hindmarsh, 1996a, b, 1999). The sediments and the rock frozen in the ice at the bottom and other side of the Glacier act like Sandpaper. In an abrasion process, debris in the basal ice scrapes along the bed, polishing and gouging the underlying rocks, similar to sandpaper on wood. The sediments and the rock frozen in the ice at the bottom and other side of the Glacier act like Sandpaper. 4) Where is the world's largest ice sheet located today? Accumulation exceeds wastage.

Abrasion and plucking are generally regarded as the dominant erosion mechanisms at the base of glaciers and ice sheets (e.g., Glasser and Bennett, 2004).Glacial abrasion is the surface wear achieved by individual clasts contained within ice or by subglacial sediment sliding over bedrock (Cuffey and Alley, 1996, Hindmarsh, 1996a, Hindmarsh, 1996b, Hindmarsh, 1999). Glacial erosion occurs in two principal ways: through the abrasion of surface materials as the ice grinds over the ground (much of the abrasive action being attributable to the debris embedded in the ice along its base); and by the quarrying or plucking of rock from the glacier bed.
