WebNov 24, 2024 · Physical weathering is caused by heating and cooling, the growth of foreign crystals, and by the collision of rock pieces during movement. Chemical weathering occurs when a rock or mineral is changed after being exposed to things like acid or oxygen. WebStudents also tend to confuse weathering (the physical or chemical breakdown of rock) with erosion (the process of transporting sediments). Even once students understand the concepts of weathering and erosion, they tend to have difficulty conceptualizing the long time frames needed for these processes to occur.
