Chemical and Mechanical Weathering Quiz

What is chemical weathering?

• The process by which rocks and minerals are broken down and altered through gravitational forces.

• The process by which rocks and minerals are broken down and altered through chemical reactions with water, air, and other substances in the environment.

• The process by which rocks and minerals are formed through volcanic activity.

• The process by which rocks and minerals are broken down and altered through physical forces such as wind and erosion.

Which of the following is an example of chemical weathering?

• The reaction between carbon dioxide and rainwater

• The erosion of a riverbank

• The formation of a volcano

• The melting of a glacier

What is mechanical weathering?

• The process of breaking down rocks into smaller pieces by changing their chemical composition.

• The process of breaking down rocks into larger pieces without changing their chemical composition.

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

• The process of changing the chemical composition of rocks without breaking them down into smaller pieces.
