Back

False.

Front

What do physical and chemical weathering both do?

Back

They break rocks into smaller pieces.

Front

What is deposition?

Back

Deposition is the process where sediments are dropped off or deposited in a new location.

Front

What is weathering?

Back

Weathering is the process where rocks get broken or weathered down.

Front

What is physical weathering?

Back

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

Front

What is chemical weathering?

Back

Chemical weathering involves the breakdown of rocks through chemical reactions, changing their composition.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering by freezing and thawing or by dissolving minerals.

Front

What is erosion?

Back

Erosion is the process of moving sediments from one location to another, often caused by wind, water, or ice.

Front

What is the difference between weathering and erosion?

Back
