What is weathering?

Back

Weathering is the breaking down of rocks into smaller pieces, known as sediment.

Front

What causes weathering?

Back

Weathering is caused by natural chemical or physical processes, such as water freezing in cracks or chemical reactions like acid rain.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass.

Front

How do plants contribute to weathering?

Back

Plants weather rocks by growing roots into cracks, which can expand and break the rocks apart.

Front

What is chemical weathering?

Back

Chemical weathering involves the breakdown of rocks through chemical reactions, such as acid rain reacting with minerals.

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks without changing their chemical composition, such as freeze-thaw cycles.

Front

What role does water play in weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rocks to break apart.

Front

What is an example of erosion?

Back

An example of erosion is a river carrying away soil and rocks from its banks.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often formed through weathering.
