What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, often involving water, acids, or gases.

Front

What is physical weathering?

Back

Physical weathering is the process that breaks down rocks into smaller pieces without changing their chemical composition, often through mechanical forces like wind or water.

Front

What is the result of weathering on rocks?

Back

Weathering causes rocks to break into smaller pieces.

Front

True or False: Chemical weathering requires a chemical reaction.

Back

True.

Front

True or False: Physical weathering involves chemical reactions.

Back

False.

Front

What is deposition in geology?

Back

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

Front

What are sediments?

Back

Sediments are small particles of rock, minerals, or organic material that have been broken down by weathering.

Front

What is erosion?

Back

Erosion is the process by which sediments are moved from one place to another, often by wind, water, or ice.

Front

How does acid rain affect rocks?

Back

Acid rain causes chemical weathering, which can dissolve minerals in rocks and lead to their breakdown.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the cracking of rocks due to freeze-thaw cycles.
