Question

1. choose the best answer.

carbonic acid and oxidation are examples of —— weathering because they change the rocks substance.
chemical
physical
dynamic
natural

Explanation:

Chemical weathering involves processes that change the chemical composition of rocks. Carbonic acid forms when carbon dioxide dissolves in water and can react with minerals in rocks. Oxidation is a chemical reaction where minerals react with oxygen. Both carbonic acid and oxidation change the rock's substance at a chemical level. Physical weathering changes the rock's physical form (like breaking into smaller pieces) without changing its chemical composition. "Natural" is too broad. "Dynamic" is not a standard term for this type of weathering classification.
