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".

http://geography.learnontheinternet.co.uk/topics/glaciation1.html WebRoches moutonnées are formed by erosional glacial processes, namely abrasion and plucking. Abrasion When a glacier moves over a protruding lump of bedrock on flatter terrain, it will exert a lot of pressure on the bedrock. This leads to an increase in the pressure melting point (PMP) of the ice.

WebPieces of rock are transported to the front of a glacier as ice within the glacier moves. Will plucking occur if a glacier is NOT advancing? Yes, because glacial ice is still moving inside the glacier even if the glacier's front is not advancing. __________ are defined as a chain of glacial lakes where each lake flows into the next.
