Plucking glacier
WebbIn glacial erosion, in addition to abrasion (q.v.) which leaves striations, gouge marks, etc., a peculiar pulling away process is called glacial plucking or quarrying, because it involves the dislodging and removal of large fragments and boulders.

WebbWhen a glacier moves downhill it erodes everything in its path through abrasion and plucking. Glaciers usually follow the easiest route down a mountain, which is often an old river valley. Webb(1) Plucking The glacier plucks big pieces of rocks from the valley floor and creates large grooves or hollows. These pieces are dragged along the valley floor as the glacier moves. The boulders and rocky floor are grounded by mutual contact. (2) Abrasion Pure ice is capable of wearing down massive rocks when equipped with angular rock fragments.
