2008-01-09 · Glaciers erode in two different ways, plucking and abrasion. Plucking happens when materials are broken from the bedrock and plucked from the place that it has been for centuries. These materials are forced to move with the glacier and causes deep scratches and large holes to be carved from the bedrock. This is called abrasion.

The process in which glaciers shape and destroy our mountains is called erosion. Erosion is a process where the rocks are broken down through transportation. Glaciers erode rock as they move down the mountains. They grind away… Glaciers erode predominantly by three different processes: abrasion/scouring, plucking, and ice thrusting. In an abrasion process, debris in the basal ice scrapes along the bed, polishing and gouging the underlying rocks, similar to sandpaper on wood. wind makes contact w/the water and some of the wind's energy is tranferred to the water, the energy that it picks up causes the water particles to move up and down as the wave goes by, but they don't move forward themselves, the wave begins to drag on the bottom as its approahes shallows water, the friction cause it the slow down, now the water does move forward with the wave Erosion by Glaciers.

•Transition from warm to cold (or water to ice) will contribute to quarrying. •Fast-flowing glaciers are likely to erode more effectively than slow glaciers. There are two main processes of glacial erosion. The first one is plucking, which is defined as the erosion and transport of large chunks of rocks. As the glacier moves over the land, water melts below the glacier and seeps into the cracks within the underlying bedrock. the glacier is called 'englacial moraine'. It is this material trapped in the ice, that allows the glacier to erode its surroundings.

•Fluctuations in water pressure will promote quarrying •In areas glaciated several times most of the glacial erosion may be completed during the first phase of glaciation. After Bennett and Glasser, 2009. Cirque. A cirque, also known as a corrie, is a valley created because of glacial erosion. The shape of … 2018-09-10 2018-06-03 2020-07-26 Glaciers erode by multiple processes: abrasion/scouring, plucking, ice thrusting and glacially-induced spalling.

Processes of glacial erosion •In general greatest erosion is associated with warm-based glaciers that have basal melting. •Transition from warm to cold (or water to ice) will contribute to quarrying. •Fast-flowing glaciers are likely to erode more effectively than slow glaciers.

Herman et al. tackle this issue by considering the Franz Josef alpine glacier in New Zealand. The amount of sediment piling up at the edge of the glacier provided erosion rates, whereas remote sensing allowed for simultaneous tracking of glacial motion. The result was a nonlinear relationship Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
