* Erosion: Glaciers erode the land by:
* Plucking: As the glacier moves, it freezes to the bedrock and pulls away pieces of rock, carrying them along.
* Abrasion: The rocks carried within the glacier scrape against the bedrock, grinding it down.
* Deposition: As the glacier melts, it releases the sediments it has been carrying. This process is called deposition and can create:
* Moraines: Ridges of sediment deposited at the edge of the glacier.
* Outwash plains: Areas of sediment deposited by meltwater flowing from the glacier.
* Drumlins: Elongated hills formed from sediment deposited by the glacier.
In summary:
* Glaciers erode the landscape by plucking and abrasion.
* Glaciers deposit sediments as they melt, creating a variety of landforms.
So, glaciers are involved in both erosion and deposition.
