Front

What is chemical weathering?

Back

Chemical weathering involves the chemical breakdown of rocks, often through reactions with water, acids, or other chemicals.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

Give an example of chemical weathering.

Back

An example of chemical weathering is limestone reacting with vinegar.

Front

What role do lichens play in weathering?

Back

Lichens release enzymes and acids that chemically break down rocks.

Front

What is deposition?

Back

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