WebAbrasion. Plucking. Plucking of glacier leads to the formation of joints and beds of underlying rocks, tearing individual blocks and drag them away. By abrasion, the glacier scratches, polishes, scraps and scour the floor of the valley with the debris frozen in it. These pieces are potent tools of denudation. Glacial plucking is the main mechanism of other small scale mechanical glacial erosion such as striation, abrasion and glacial polishing. The heavier the sediment load, the more extreme the erosion of the downhill landscape. Erosion is largely dependent on the amount of water flow and its velocity, the clast … See more Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the weathering and erosion of pieces of bedrock, especially large "joint blocks".
