Glaciers knock off and drag very hard boulders and gravels on their path to melting. The contact points between the entrapped rocks and the surrounding bedrock act like a giant piece of sandpaper, either scratching grooves in, or smoothing the abraded surface.

The glacial scouring by bedrock embedded in ice is erosion by?
Abrasion
What are the three main types of glacial erosion?
The 3 main types of glacial erosion are plucking, abrasion and freeze thaw.
Describe two basic processes of glacial erosion?
The two processes are abrasion and plucking.What processes lead to glacial erosion? Describe them.The two main processes that lead to glacial erosion are plucking and abrasion. Plucking is the process by which a glacier picks off rocks as it blocks over the land. The rock fragments freeze to the bottom of the glacier, gouging and scratching the bedrock as the glacier advances in the process of abrasion.
What is a glacier groove?
a glacier groove is when it scratches or gouges or cuts into bedrock's by the process of glacial abrasion.

What does glacial polish results from?
Abrasion, when the ice and the load of rock fragments slide over the bedrock

How do glaciers help?
Glaciers can produce boulder clay which is the result of glacial abrasion. Boulder clay forms the basis of clay type soils in England.
What are the types of erosion?
Erosion is the process of the movement of materials from one place to another, and the four agents of erosion are ice, water, wind, and gravity. Two types of glacial erosion are plucking and abrasion
Can mass movement cause long striations on the surface of a rock?
Yes. One very good example would be the striations caused by glacial abrasion. Please see the related link for more information.
What is abrasion resistance?
abrasion resistance is the resistance in abrasion
