WebAug 8, 2010 · Wind, rain, and water are constantly eroding material from every exposed surface. To add to the forces of erosion are the effects of chemical weathering. Some of the results of chemical weathering dealt with on this page include: Vast underground cave systems. Sinkholes. Stalactites and stalagmites. The rusting of steel and iron structures. WebScientists 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.

How does chemical weathering occur in nature

WebChemical weathering includes carbonic acid and hydrolysis, dissolution, and oxidation. Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment and soil from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes (see Chapter 10, Mass Wasting) move ... WebSep 9, 2024 · Chemical weathering weakens rocks making them more prone to breaking physically, while mechanical weathering increases the surface area of the sediment, which increases the surface area that is exposed to chemical weathering. Therefore, environments with multiple types of weathering can erode very quickly.
