Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

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 occurring after erosion.

Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks without changing their chemical composition, often caused by temperature changes, freezing, and thawing.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or gases.

Front

What role do glaciers play in erosion and deposition?

Back

Glaciers erode the landscape as they move, carrying away rocks and sediments, and deposit them when they melt.

Front

What is abrasion in the context of erosion?

Back

Abrasion is the process of wearing down surfaces through friction, often caused by wind or water carrying particles that scrape against rocks.

Front

What is an example of biological weathering?

Back

An example of biological weathering is the action of plant roots growing into cracks in rocks, causing them to break apart.

Front

How does animal action contribute to weathering?

Back

Animal action contributes to weathering by burrowing, digging, or trampling, which can break down soil and rock.

Front

What is the difference between erosion and weathering?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials from one place to another.
