controlled by the spatial pattern of glacier processes such as erosion and deposition landforms within a landscape, and the differences between landscapes in
Glaciers have carved some of Earth’s most beautiful landscapes by steepening and deepening valleys through erosion. Think of the Scottish Highlands, Yosemite National Park in the US, or the Norwegian Fjords. But big questions remain about how glacial erosion works. Valley glaciers form several unique features through erosion. You can see some of them in Figure below and at this link: [Insert a link to a video that shows features eroded by valley glaciers.] As a valley glacier flows through a V-shaped river valley, it scrapes away the sides of the valley.

The weight of a glacier makes it easy to break rocks and boulders in pieces. Once all the rocks fragments are picked up they are carried around wherever the glacier goes. Yosemite Nature Notes 12: Glaciers. Yosemite National Park is famous for its spectacular glacially carved landscape. Although glaciers have come and gone many times in the past, there are still two active glaciers near Yosemite's highest peaks.

A glacier's weight, combined with its gradual movement, can drastically reshape the landscape. Over hundreds or even thousands of years, the ice totally changes the landscape. The ice erodes the Valley Glacier. a long, narrow glacier that forms when snow and ice build up in a mountain valley.
5 Oct 2016 The intermittency in glacial erosion is postulated to occur via changes in glacier extent and sliding velocity, which should reflect climate forcing
These landscapes have distinct features which are 5 Oct 2016 The intermittency in glacial erosion is postulated to occur via changes in glacier extent and sliding velocity, which should reflect climate forcing How Glaciers Form Glaciers are sheets of solidly packed ice and snow that cover large areas of land. They are formed in areas where the general temperature is We conclude that landforms of glacial erosion are of great value in ice mass and glacial erosion in landscape evolution: the Ben Ohau Range, New Zealand.
As glaciers flow over bedrock, they soften and lift blocks of rock into the ice. This process, called plucking, is caused by subglacial water that penetrates fractures in the bedrock and subsequently freezes and expands. Through both erosion and deposition, glaciers have A DRAMATIC affect on the landscape. Glaciers erode the underlying surface, through plucking, by glacial meltwaters, through abrasion. Plucking abrasion and the work of glacial metlwaters are the three primary ways in which glaciers ERODE. Match the characteristic/feature of a glacier or glacial area with its description.

Although glaciers have come and gone many times in the past, there are still two active glaciers near Yosemite's highest peaks. A continental glacier is a glacier that covers much of a continent, or a large island. They can spread out over millions of square kilometers.

As the glaciers overflow the cirque, they move downward. They dig deep into the terrain, forming rugged, dramatic landscapes. As they move, glaciers erode or wear away the land beneath and around them. Glaciers carry great amounts of soil, rock, and clay.
