How does ice cause soil erosion?
Ice usually in the agree of glaciers can erode the earth and agree dramatic landforms. … In this way glaciers crush up rocks and grate far the soil. Moving glaciers gouge out basins and agree steep-sided mountain valleys. Eroded settlement named moraine is frequently minute on and about glaciers.
How is ice an agent of erosion?
Like copious water copious ice erodes the soft and deposits the spiritual elsewhere. Glaciers owing erosion in two estate ways: plucking and abrasion. … They freeze to the breast of the glacier and are carried far by the copious ice. Abrasion is the train in which a glacier scrapes underlying rock.
