WebGlaciers, also known as “rivers of ice,” actually flow. Gravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. A glacier molds itself … A glacier retreats when more ice melts away during the summer than that which forms during the winter. The glacier reduces in size as the ice in the zone of wastage melts. The retreating glacial ice never actually flows backwards; the ice simply melts away faster than is replenished from new glacial ice formation in … See more Continental glaciers (ice sheets, ice caps) are massive sheets of glacial ice that cover landmasses.

WebThey are different because valley glaciers form when snow and ice form in a mountain valley. They are kept from spreading by the mountains. Continental glaciers can spread out over millions of square kilometers they can flow in all directions as they move. How do glaciers form. Glaciers can form only in an area where more snow falls than melts. WebGlaciers move because the surface of the ice is sloped. This generates a stress on the ice, which is proportional to the slope and to the depth below the surface. As shown in Figure 16.12, the stresses are quite small near …

WebAs a glacier flows downslope, it drags the rock, sediment, and debris in its basal ice over the bedrock beneath it, grinding it. This process is known as abrasion and produces scratches (striations) in bedrock surface. … Web14.1 Glacier Formation. Glacier in the Bernese Alps. Glaciers form when repeated annual snowfall accumulates deep layers of snow that are not completely melted in the summer. Thus there is an accumulation of snow that builds up into deep layers.
