Weathering, Erosion, and Deposition

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into sediment.

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical weathering and chemical weathering.

Front

What is mechanical weathering?

Back

Mechanical weathering is the type of weathering that occurs when rock is physically broken down into smaller pieces.

Front

What is chemical weathering?

Back

Chemical weathering is the type of weathering that occurs when rocks weaken and break down due to chemical changes in the composition of the rock.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

Front

What are some common agents of erosion?

Back

Common agents of erosion include water, wind, ice, and gravity.

Front

What is deposition?

Back

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

Front

How does erosion differ from weathering?

Back

Erosion involves the movement of sediment, while weathering involves the breaking down of rocks without movement.

Front

What is a landslide?

Back

A landslide is a rapid movement of rock and soil down a slope, which is NOT considered a slow change to Earth's surface.

Front

What role does water play in weathering?

Back

Water can cause both mechanical and chemical weathering, such as through freeze-thaw cycles and chemical reactions.
