Back

Weathering

Front

What type of weathering involves the breakdown of rocks through chemical reactions?

Back

Chemical Weathering

Front

Which of the following is NOT an agent of chemical weathering: carbon dioxide, acid rain, ice wedging, oxidation?

Back

Ice wedging

Front

How do plants contribute to the weathering of rocks?

Back

Plants weather rocks when their roots grow into cracks and expand the rock.

Front

What type of weathering is characterized by the physical breakdown of rocks without changing their chemical composition?

Back

Mechanical Weathering

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

Front

What is deposition in the context of weathering and erosion?

Back

Deposition is the process where eroded materials are dropped off in a new location.

Front

What role does acid rain play in weathering?

Back

Acid rain contributes to chemical weathering by reacting with minerals in rocks.

Front

What is the difference between mechanical and chemical weathering?

Back

Mechanical weathering physically breaks rocks apart, while chemical weathering alters the minerals in rocks.

Front

Give an example of biological weathering.

Back

An example of biological weathering is when tree roots grow into rock cracks and break them apart.
