Weathering, Erosion, and Deposition

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is deposition?

Back

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

Front

What is mass movement?

Back

The downslope movement of soil and weathered rock due to the force of gravity.

Front

What role does gravity play in erosion?

Back

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

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, often involving water and atmospheric gases.

Front

Give an example of chemical weathering.

Back

Oxygen in the atmosphere reacting with iron in rocks, causing them to rust and turn red.

Front

What are the agents of erosion?

Back

Water, wind, ice, and gravity are the main agents of erosion.

Front

Which of the following is NOT an agent of erosion?

Back

Heat is not considered an agent of erosion.

Front

What is physical weathering?

Back

The process of breaking rocks into smaller pieces without changing their chemical composition.
