Weathering

What is mechanical weathering?

Back

Mechanical weathering is the process of physically breaking down rocks into smaller pieces without changing their chemical composition.

What is abrasion in the context of weathering?

Back

Abrasion is a type of weathering that occurs when rocks are worn smooth by the friction of wind or water carrying smaller particles.

What happens to water when it freezes?

Back

Water expands when it freezes, which can cause cracks in rocks.

What is the role of ice wedging in weathering?

Back

Ice wedging occurs when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

Front

What is the difference between weathering and erosion?

Back

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

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass.
