Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and minerals into smaller pieces without changing their chemical composition.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

What does WED stand for?

Back

WED stands for Weathering, Erosion, and Deposition.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, often changing the minerals in the rocks.

Front

What is physical weathering?

Back

Physical weathering is the process that breaks rocks into smaller pieces without changing their chemical composition, often due to temperature changes or pressure.

Front

How does water contribute to erosion?

Back

Water contributes to erosion by flowing over land, carrying away soil and rock particles.

Front

What role do glaciers play in erosion?

Back

Glaciers erode land by scraping and grinding the surface as they move, transporting large amounts of sediment.

Front

What is an example of deposition?

Back

An example of deposition is when a river slows down and drops off sand and gravel at its mouth, forming a delta.

Front

How does wind cause erosion?

Back

Wind causes erosion by lifting and carrying away loose particles of soil and sand, especially in dry areas.
