Glaciers weather and erode rock material primarily through processes like abrasion and plucking. As glaciers move, the ice at their base contains rocks and debris that scrape against the bedrock, grinding it down through abrasion. Additionally, as glaciers advance, they can exert pressure on the underlying rock, causing fractures that lead to plucking, where chunks of rock are dislodged and carried away by the ice. This combined action reshapes the landscape, creating features such as valleys and fjords.

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.
How do glaciers erode rock?
Glaciers erode rock through processes like plucking and abrasion. Plucking involves the freezing of water within cracks in the rock, causing pieces of rock to be pulled out as the glacier moves. Abrasion occurs when the glacier carries rocks and debris that scrape against the rock surface, wearing it down over time.
When a glacier leaves behind a rock that is of completely different material composition than the formation it is deposited upon its called?
The rock is called a glacial erratic when it is left behind by a glacier, and is of a completely different material composition than the rocks on which it was deposited.
When a glacier leaves behind a rock that is of completely different material composition than the formation it is deposited upon it is called what?

What is glacial load?
Material (such as rock) which is carried by a glacier.
What happened to Rock formations as they age?
They weather and erode, forming sediments.
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.
What formed when rock material is dropped at the front of a glacier?
terminal moranies
What body of water can cause a rock to weather?
he constant movement of water anywhere causes rocks to erode and weather.
How do glaciers move boulders?
As a glacier or ice sheet moves, it can erode bedrock. The ice can then pick up, or entrain, the eroded rock. As the ice flows, it transports the bedrock debris in the direction of flow.
What property of water allows it to form sinkholes?
It's ability to weather and erode rock.
What moraines form when rock material is dropped at the front of a glacier?
terminal moranies
What moraines forms when rock material is dropped at the front of the glacier?
terminal moranies
