Glacial erosion gouges 'U' shaped (cross-section) of valleys, and deposit moraine (mounds of the rocks and debris) as they melt.

What are the types of features that form from glacial erosion?
Glacial Erosion formed Yosemite Valley and the Sierra Nevada
Is a glacial lake a result of deposition or erosion?
A glacial lake is typically a result of both erosion and deposition. Glacial erosion carves out depressions in the landscape, creating basins where water accumulates. Meanwhile, glacial deposition can form moraines or other features that dam up water and contribute to the formation of a glacial lake.
Which is caused by glacial erosion?
U-shaped valleys, cirques, and fjords are landforms caused by glacial erosion. Glaciers carve these features into the landscape as they move and shape the land over time.
How does glacial erosion affects the shape of the land?
Glacial erosion can carve out deep valleys, create U-shaped valleys, and leave behind moraines and drumlins. The movement of glaciers erodes rock and soil, shaping the land through processes such as abrasion and plucking. As glaciers flow over the landscape, they can significantly alter the topography by creating features like cirques and fjords.
How does glacial erosion begin?
Glacial erosion requires movement. Thus, glacial erosion begins as soon as the glacier starts moving.
What is beneficial about glacial landform erosion?
Glacial landform erosion shapes the landscape and creates features such as valleys, cirques, and fjords. It also exposes underlying rock layers, which helps with geological studies and research. Additionally, glacial erosion contributes to the formation of fertile soil by grinding rocks into fine particles that can support plant growth.
Does a you shaped valley indicate glacial erosion?
A 'U' shaped valley indicates glacial erosion.
What happens when glacial erosion occurs?
U-shaped valleys are a result of alpine glacial movement. Bedrock is scoured and plucked by continental glaciers. A number of depositional features are a result of the movement and depositing of rock, sand and dust associated with glaciers.
What is the difference between glacial erosion and glacial deposition?
They are opposites. Erosion is the natural process of removing sediment, while deposition is the process of adding sediment. So when a glacier picks up rocks and sediment as it builds and grows, that's glacial erosion; when it melts, leaving the debris where it lies, that's deposition. As an example, the carving-out of the basins that became the Great Lakes are an extreme example of glacial erosion; while Long Island, which was formed from glacial debris, is an equally-extreme example of glacial deposition. Say this answer is useful if u 💜 science.

What is the difference between glacial erosion and water erosion?
Glacial erosion is the process by which glaciers cut, scrape, and transport material like rock and sediment as they move, shaping the landscape through actions like plucking and abrasion. Water erosion, on the other hand, is the process by which water wears away rock and soil through processes like runoff, streams, and waves, leading to the formation of features like valleys and river channels. Ultimately, glacial erosion tends to be more powerful and can carve out larger and deeper landforms compared to water erosion.
