Web1) climate must be cold enough that winter snow doesn't melt completely away 2) there has to be enough snowfall that a large amount can accumulate, even during the summer 3) the surface that the snow falls on must have a gentle slope so that snow doesn't slide, and it also needs to be protected from wind WebValley glaciers sometimes flow through narrow inlets (fjords) into the ocean. They over-steepen the walls around them, as they do when carving u-shaped valleys. Thus, fjords have tall, steep walls like glacial valleys, but … csmls meaning

How are continental glaciers and valley glaciers different?

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.

Cirques (U.S. National Park Service)

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 7, 2024 · Ice Flow: Glaciers move by internal deformation (changing due to pressure or stress) and sliding at the base. What are 2 different ways glaciers shape the land? There are three distinct ways that glaciers shape the land: 1) erosion 2) transportation and 3) deposition.
