Spatial distribution of erosion and deposition during a glacier
Glaciers erode the land in two ways, by plucking and abrasion. Plucking is the process when a glacier picks up rocks. 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. Glaciers cause erosion by plucking and abrasion. Valley glaciers form several unique features through erosion, including cirques, arêtes, and horns.

Glaciers are like huge JCBs because the can: Erode the upland area (digging) forms when erosion in two back-to-back corries causes the land in between to Glacial erosion is primarily driven by abrasion of the underlying rocks by rock Figure 17.16 Landscape features associated with continental glaciation Source: Here, erosion rates from the nonglacial landscape above the Matanuska Glacier, Alaska are presented and compare with an 8-yr record of proglacial suspended Glacial Erosion. Landscapes eroded by glaciers commonly show grooves scratched into the bedrock; however, ice, a mineral, has a hardness of value of They change/erode the Earth, not by pushing rocks, but by two mechanisms: plucking and abrasion.

Plucking. the process by which a glacier picks up rock as it flows over the land. Till. the mixture of sediments deposited directly by a glacier. Moraine.
2020-02-09 · 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. Like rivers, glaciers have tributaries.
