A glacier erodes by the following processes:
- Plucking: the physical plucking of rocks from the rock face beneath it by freezing around it, then moving forwards, pulling it with it.
- Abrasion: the scraping of a rock entrained within the glacier against the rock face
- Removal: rocks can be entrained within the glacier, at the sides, in the middle or at the bottom and are transported by the processes listed below
Do not confuse the following with erosion:
- Rotational slip: related to erosion closely. This is where the corrie glacier rotates round in the hollow, carving it out, but the actual erosion is done by the processes above
- Glacial movement: a glacier moves by four processes: rotational slip, basal slippage, internal deformation and due to gravity. This is not the physical erosion of the rock, but just the way in which the glacier moves.

What process Do glacier erode the land?
When a glacier melts, it deposits the sediment it eroded from the land, creating various landforms.
What are two processes by which glacier erode the land?
Plucking and Abrasion.
How can a iceberg create weathering?
As an iceberg - or glacier - moves across land, it will scrape against it, causing it to weather/erode the land.
What determines the rivers ability to erode the land beneath it?
Type of land surface, speed and volume of water.
What is melting water at base of the glacier that helps the ice move over land?
The melted water at the base of a glacier acts as a lubricant, reducing friction between the ice and the land beneath it. This helps the glacier slide over the land more easily, contributing to the movement of the glacier.
What is a large mass of snow and ice that moves slowly over land?
Any large mass of ice that moves slowly over ice is called a glacier.
How is a glacire formed?
glacier are river of ice which to erode the land scape by bulldozing soil and stones to expose the solid rock below.
How can glaciers erode rocks?
The glacier can carry rocks. The moving of the glacier.
How does glaciers erode by abrasion?
Glaciers erode by abrasion when they drag rocks and sediments along their base and sides, creating a sandpaper effect. This process occurs as the glacier moves, grinding, scratching, and smoothing the underlying bedrock and carving out deep valleys. The debris carried by the glacier further enhances the abrasion process as it scrapes against the surface.
How does a glacier affects the land?
A glacier can completely reshape the land. As it is made of very heavy ice, this ice can erode surfaces from the debris and rocks that it carries and the amount of pressure it places on the surface beneath it during its movement.
Abrasion and plucking involves what part of glacier?
The base of the glacier, where it is in contact with the rocks beneath it.
What are two ways in which glaciers erode earth's suface?
Glaciers erode Earth's surface through abrasion, where the ice and sediments grind against the rock, wearing it down. They also erode through plucking, where the glacier freezes onto rock and plucks or pulls it away as the glacier moves.
