Glaciation represents a profound exogenic geomorphic agent transforming alpine and continental terrains through continuous mechanical processes of plucking, frost wedging, and basal abrasion. Glacial bodies originate where annual snowfall accumulation exceeds ablation over protracted climatic spans, undergoing firn compaction into dense crystalline ice. As gravitational forces drive downhill ice movement, glaciers carve distinctive erosional landforms. Bowl-shaped amphitheater hollows designated as cirques (or corries) form at valley heads, frequently hosting glacial tarn lakes upon retreat. Sharp pyramidal horns like the Matterhorn and serrated knife-edge ridges termed aretes emerge where converging cirques erode dividing interfluves. Glaciers reshape pre-existing V-shaped fluvial valleys into steep-sided, flat-floored U-shaped valleys or glacial troughs, leaving truncated spurs and hanging valleys occupied by tributary cascades. Conversely, sediment transport and ice melting generate unsorted glacial till and stratified glaciofluvial depositional landforms. These include lateral, medial, and terminal moraines, streamlined asymmetric drumlin swarms, sinuous esker ridges of subglacial stream gravel, and kettle holes scattered across proglacial outwash plains. In the Himalayas, Siachen Glacier in the Karakoram Range constitutes one of the longest non-polar valley glaciers, providing critical meltwater nourishment to the Indus River drainage network.
