Because ice doesn't change the chemical make-up of a rock. It can however, when liquid, get into a crack in the rock and then freeze. When water freezes, it expands by about 9%. If you've ever had a...
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside...
There has to be the action of water, oxygen, Carbon Dioxide, living organisms, and acid rain to be Chemical Weathering. Mechanical Weathering makes smaller rocks the sameComposition
Both chemical and mechanical weathering breakdown a rock into particles, just in diffrent ways. Mechanical weathering is the physical weathering in which a rock is broken down into particles....
