What way does the valley glacier flow? - Answers

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. Continental glaciers are currently eroding deeply into the bedrock of Antarctica and Greenland. The vast ice sheets are … See more If the amount of glacial ice formation in the zone of accumulation equals the amount of melting in the zone of wastage, then the glacier does not advance or retreat. While the ice within the glacier continues to flow … See more The upper 50 meters of the surface of the glacier, where the ice does not undergo plastic deformation, is referred to as the zone of fracture. In … See more Glaciers have a snow budget, much like a monetary bank account. The more money deposited into a bank account, the larger the account grows. … See more WebValley glaciers usually start life in either corries or ice sheets. Glacial ice flowing down hill from either of these sources will follow any existing valleys or easy routes, eroding and enlarging them as it moves. Often … 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.

WebIn an alpine glacier, the ice flows down the slope of the underlying valley. Continental glaciers do not have a sloped surface to flow down. What feature of a continental glacier facilitates its flow? 6. What does the equilibrium line represent in a glacier? Explain. 7. WebLarge valley glacier systems consist of numerous cirques and smaller valley glaciers that feed ice into a large trunk glacier. Because of its greater ice discharge, the trunk glacier has greater erosive capability in its middle and lower reaches than smaller tributary glaciers that join it there. The main valley is therefore eroded more rapidly than the side valleys. With …

WebJul 8, 2024 · Antarctic glaciers flow from the inland to the shore, forming an ice shelf or glacier tongue, and are eventually discharged into the ocean. As the motion of the glacier is closely related to the seaward ice flux, ice flow velocity is an important indicator of global climate change and sea level rise [1,2,3].The flow velocity of a glacier changes due to … http://www.geography-site.co.uk/pages/physical/glaciers/valley.html
