How does glacial erosion and glacial deposition affect the face of the earth?
Glacial erosion shapes the land by scraping and polishing the surface, creating features like U-shaped valleys and cirques. Glacial deposition occurs when the ice melts and deposits the sediments it carried, forming landforms like moraines and drumlins. Together, these processes have significantly shaped the Earth's landscape over millions of years.
What is the difference between glacial erosion and glacial deposition?
Glacial erosion refers to the process where glaciers wear away the land by scraping and gouging the surface, while glacial deposition is the process where glaciers deposit materials like rocks, sediments, and other debris that they pick up as they move. Erosion creates features like U-shaped valleys and cirques, while deposition creates features like moraines and drumlins.
What type of glaciers are there and how do they erode the land?

How are glacial plains formed?
Glacial plains are formed by the deposition of sediments carried by glaciers as they advance and retreat. When glaciers move, they pick up rocks, soil, and other materials, which are then deposited when the glacier melts. Over time, these deposited materials accumulate to create flat, wide expanses of land known as glacial plains.
Is glacial lake caused by erosion or deposition?
Glacial lakes are primarily caused by deposition. As glaciers move, they erode the land beneath them and create depressions where meltwater collects, forming glacial lakes. The deposition of sediment carried by the glacier contributes to the formation and shape of the lake.
