What is the difference between weathering and erosion? how are mechanical weathering and chemical weathering different? how are hydrolysis and oxidation similar? explain the process of exfoliation. as waves crash into rock along the shoreline, particles of sand, shell, and other materials in the ocean water loosen tiny bits of sediment from the rock. as the waves recede, they carry the sediment away. in this scenario, which process represents weathering, and which process represents erosion?
