Chemical and Physical Weathering

Front

What is the relationship between surface area and the rate of weathering?

Back

As surface area increases, the rate of weathering increases.

Front

True or False: Chemical weathering does not change the mineral composition of the weathered rock.

Back

False.

Front

What is an example of chemical weathering that involves rust formation due to oxygen exposure?

Back

Oxidation.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process through which rocks are physically broken into smaller pieces.

Front

True or False: The more surface area of a rock is exposed, the more chemical weathering can occur.

Back

True.

Front

What are the two main types of weathering?

Back

Chemical weathering and physical (mechanical) weathering.

Front

Define chemical weathering.

Back

Chemical weathering involves the breakdown of rocks through chemical reactions, altering the mineral composition.

Front

What is the primary agent of chemical weathering?

Back

Water is the primary agent of chemical weathering.

Front

How does temperature affect weathering rates?

Back

Higher temperatures generally increase the rate of weathering.

Front

What role do plants play in weathering?

Back

Plants can contribute to weathering through root expansion and the production of organic acids.
