U-shaped valleys - glacial erosion versus V-shaped valleys where are characteristic of rounded hollow carved into a mountain at the head of a glacial valley.
A crevasse into which rock debris is falling from the glacier's surface. With it's load of abrasive rock fragments, the base of the glacier acts like a belt sander, scraping across the rock, eroding it, producing characteristic erosional features, and creating a supply of material that leads eventually to the formation of depositional features as well.

Glaciers can also erode sediment. This can happen in a number of ways, including downward creep of the glacier ice into the sediment, freezing of water in sediments to the base of the glacier, and squishing the sediment around beneath the weight of the ice. How do glaciers erode? When gravity causes ice to move down the side of a mountain there are two ways in which the rock below is eroded.

These combined forces break up the rocks and erode the peaks into their stark, sculpted forms. Falling ice, rocks and gushing water wear away at the mountain slopes. The ice and rock debris accumulates in the valleys and flows downwards as slow moving glaciers. When these melt, piles of rock debris called moraines are left behind.

They are formed in areas where the general temperature is usually below freezing. This can be near the North and South poles, and also on very high ground,
Ice can not only erode mountains but also protect them from erosion. Depending on glacier regime, even steep alpine lands can be preserved through time with the help of ice.

Glaciers are solid ice that move extremely slowly along the land surface. They erode and shape the underlying rocks. Glaciers also deposit sediments in characteristic landforms. The two types of glaciers are: continental and alpine. Continental glaciers are large ice sheets that cover relatively flat ground.
2008-06-06 A valley glacier is a long, narrow glacier that forms when snow and ice build up in a mountain valley. The sides of mountains keep these glaciers from spreading out in all directions. Instead, they usually move down valleys that have already been cut by rivers. Valley glaciers are found on many high mountains. How Glaciers Erode And Transport Sediment .
