Glacial Landforms in Relation to the Himalayas

Glaciers are represented by the flowing movement of a thick mass of ice and form as a result of the compaction or recrystallization of snow. Glaciers occur in areas whose climate favours the seasonal accumulation of snow in greater volumes than seasonal ablation. Here the seasonal accumulation of snow outpaces seasonal ablation that occurs due to loss of snow from melting, calving, evaporation and/or wind erosion. Glaciers can thus be found in Polar and Alpine Regions where temperatures can be substantially...
