Weathering, Erosion & Deposition

Front

What is chemical weathering?

Back

The breakdown and decomposition of rocks as a result of chemical reactions and processes.

Front

How do plants contribute to weathering?

Back

Plants weather rocks when their roots grow into cracks of rocks and expand, causing the rock to break.

Front

What is weathering?

Back

The process by which rocks are broken down into smaller pieces.

Front

What is physical weathering?

Back

The process of breaking down rocks without changing their chemical composition, such as through freezing and thawing.

Front

What is an example of physical weathering?

Back

Water gradually wearing down and smoothing rocks over a long period of time.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another.

Front

What is deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass.

Front

What causes chemical weathering?

Back

Chemical weathering is caused by chemical reactions, such as oxidation, hydrolysis, and carbonation.

Front

What is an example of chemical weathering?

Back

The reaction of carbon dioxide with water to form carbonic acid, which can dissolve limestone.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering by freezing in cracks or reacting with minerals.
