Through the process of erosion, these fragments are removed from their … WebThis is called weathering. Scientists categorize the processes that break down rock in two groups: physical and chemical weathering. Physical (also called mechanical) weathering happens when forces (pushes and pulls) repeatedly act on the rock. An example is wind repetitively gliding against a rock taking rock particles with it.

WebRocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.
