The two processes by which glaciers erode land are called plucking and abrasion. PLUCKING~~ When a glacier flows over the land, plucking picks up rocks in a process. ( All ready said what abrasion is earlier on ) When a glacier melts, it deposits the sediment it eroded from the land, creating landforms.

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.

How do glaciers erode the land? Glaciers are erosional behemoths. Glaciers can tear down mountains faster than any other geologic process. As glacial ice flows in a fluid manner, it erodes the surface in two primary ways: ICE PLUCKING: Ice plucking fills between cracks and rips sediments by freezing and thawing.

When a large amount of plucking has occurred this increases the rate of abrasion as more rock is embedded in the base of the glacier. At the top end of the glacier, the ice doesn’t move in a straight line — it moves in a circular motion called rotational slip. This can erode hollows in the landscape and deepen them into bowl shapes called corries.

Glaciers erode the land (mostly by plucking and abrasion), creating many specific landforms in their wake. See the image below to see how these various Glaciers-. Important in understanding global scale climate change.

produces rock flour (pulverized rock) and glacial striations (grooves in the bedrock) Glaciers cause erosion since they are in form of a block of snow which will melt and erode the land. This can be in form of abrasion, freeze-thaw or plucking. During summer the glaciers melt down and rich source of pure water is obtained.

Glaciers are big ice masses covering a large area sometimes larger than a state. As the ice melts, glaciers move back and forth wearing away at the land. This causes the land to break apart or erode. That usually occurs in the summer. In the winter, the ice freezes up again so the glacier stays in one spot. As a glacier flows over the land, it picks up rocks in a process called plucking; Due to the glaciers extreme weight, it can break rocks apart and then the rocks freeze to the bottom of the rock carrying it with it when it moves; As rocks remain on the bottom of the glacier and it drags them across the land, abrasion occurs as it scratches the Glaciers cover about 10% of the land surface near Earth’s poles and they are also found in high mountains.

This leaves Glaciers erode the land primarily in two ways ― Abrasion – scratching and polishing of rocks o Rocks within the ice acting like sandpaper to smooth & polish the surface below glacial striations rock flour (pulverized rock) ― Plucking – lifting of rocks V.
