What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

What is deposition?

Back

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

How do plants contribute to weathering?

Back

Plants can break down rocks through root growth and the production of organic acids that chemically weather minerals.
