Chapter 8 - Erosion and Deposition

Front

What is mass wasting?

Back

Mass wasting refers to the movement of soil and rock down a slope due to the force of gravity.

Front

What is the difference between glacial till and outwash?

Back

Till is unsorted material deposited directly by a glacier, while outwash is sorted material carried away by meltwater from a glacier.

Front

What is chemical weathering?

Back

Chemical weathering is the process by which rocks break down due to chemical reactions, such as water dissolving minerals.

Front

What is erosion?

Back

Erosion is the process of wearing away and transporting soil and rock from one location to another.

Front

What is deposition?

Back

Deposition is the process by which sediments are laid down in new locations after being transported by wind, water, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks into smaller pieces through physical or chemical processes.

Front

What is an example of physical weathering?

Back

An example of physical weathering is ice breaking rocks into pieces.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is water dissolving minerals out of rock.

Front

What causes mudflows?

Back

Mudflows are caused by heavy rainfall or rapid snowmelt that saturates the soil, leading to a flow of mud down a slope.

Front

What is the role of gravity in erosion?

Back

Gravity is the primary force that drives the movement of materials down slopes, contributing to erosion.
