The resulting deposits are termed glacial drift. The rate of erosion is determined by several factors such as the velocity of flow, gradient of the slope, the weight of the glacier, the temperature of the ice and the geological structure of the valley. The valleys may comprise scattered debris or debris moulded as moraines with swampy. – Civil Engineering Course by Engineers Career Group, GATE (2012) Class XI NEET This leads to the formation of various landforms like cirque, hanging valley and aretes.
