Flexi Says: Weathering breaks down Earth's materials into smaller pieces. Mechanical weathering breaks down existing rocks and minerals. Mechanical weathering keeps the chemical makeup of materials the same. Chemical weathering is different than mechanical weathering. The minerals in the rock change their chemical makeup. They become a different type of mineral or even a different type of rock. Chemical weathering works through chemical reactions that change the rock. The chemical weathering can occur at different stages as high weathering occurs at low depth while low or slight weathering at higher depth.
