Explain how chemical weathering differs from physical weathering.

Answer 1

Chemical weathering is the process of breaking down rocks and minerals through chemical reactions. This results in the formation of new compounds and minerals that are more stable in the new environment. The primary agents of chemical weathering are water, oxygen, and carbon dioxide, which react with minerals in rocks to form new compounds.

Physical weathering is the process that breaks down rocks into smaller pieces without changing their chemical composition. Physical weathering can be caused by various agents, including ice, frost, wind, rain, and temperature changes. The primary result of physical weathering is the formation of smaller fragments of rocks, often with rough surfaces.

In summary, chemical weathering involves the breaking down of rocks through chemical reactions, while physical weathering involves the breaking down of rocks into smaller pieces without changing their chemical composition.
