Erosion and Deposition

Front

What is erosion?

Back

Erosion is the process by which natural forces move weathered rock and soil from one place to another.

Front

What is deposition?

Back

Deposition is the process that lays down sediment in a new location.

Front

What is plucking in the context of glacial erosion?

Back

Plucking is the process where glaciers drag rocks, producing grooves and scratches in bedrock.

Front

What is abrasion?

Back

Abrasion is the process of wearing away rock surfaces by friction and impact, often caused by moving ice or water.

Front

What is sheet erosion?

Back

Sheet erosion is a type of water erosion that occurs when runoff flows in a thin layer over the land.

Front

What is loess?

Back

Loess is sediment made up of fine particles of silt that have been deposited far from their source by wind.

Front

What are the main agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

How does water contribute to erosion?

Back

Water contributes to erosion through processes like runoff, which can carry soil and rock away.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of materials, while weathering is the breaking down of rocks and minerals without movement.

Front

What is mass erosion?

Back

Mass erosion refers to the movement of large amounts of earth material down a slope due to gravity.
