WebFeb 11, 2024 · Chemical weathering is when chemicals in rain and moving water react with rocks and minerals to change or weaken them in some way. Chemical weathering always causes some type of chemical reaction within the rock or mineral itself. Expand your knowledge of the breaking down of rocks and soil through examples of erosion. WebWedging, also know as frost wedging, is a process of freezing and thawing occur over and over again in a cycle. When water gets into the cracks of rocks and then freezes, the cracks expand and become enlarged which creates angular fragments to occur. This can happen to a bottle that youstick in your freezer at home, too, according to our textbook.
