Glaciers are huge chunks of snow and ice most time more than 1000 feet thick. They weigh huge amount and overtime become so condensed that they are harder than the rock they are on top of. They move at slow rates and the ice and erodes the rock into a fine powder that is then left behind. They erode the rock over hundreds of years and create huge valleys.

ViviGlaciers cause erosion through a process called plucking, where they pick up and carry rock and sediment as they move. The weight and pressure of the ice cause the glacier to scrape against the bedrock, grinding it down and carving out landscapes. As the glacier melts, the sediment it carried is deposited, reshaping the land.

Do glaciers cause water erosion?
Yes, glaciers can cause water erosion through a process known as glacial erosion. As glaciers move, they pick up and transport rock and sediment, which can erode the land beneath them. When glaciers melt, they release large amounts of water that can further contribute to erosion through processes like glacial meltwater erosion and glacial outwash deposition.
Can valleys cause erosion?
Yes, valleys can cause erosion. The flow of water through valleys can carve out the land, carrying away soil and rock particles. Additionally, glaciers moving through valleys can also contribute to erosion by grinding and transporting material.
Is esker cause by glacial erosion?
No, eskers are not caused by glacial erosion. Eskers are long, winding ridges of sand and gravel that are formed by meltwater streams flowing in tunnels within or under glaciers. Glacial erosion refers to the process by which glaciers carve and shape the land through the movement of ice and debris.
The three most common agents of erosion are .?
water, wind, and ice
What are the four forces that can cause erosion give an example of each?
The four forces that can cause erosion are water (rainfall and rivers), wind (abrasion by wind-blown particles), ice (glaciers carving out valleys), and gravity (mass wasting like landslides). An example of water erosion is a river carving out a canyon, wind erosion can be seen in the formation of sand dunes, ice erosion is evident in U-shaped valleys carved by glaciers, and gravity erosion can result in rockslides on steep slopes.
