Summary:Weathering occurs because rocks are exposed to physicochemical conditions different from those under which they were formed. Most primary minerals contained in these rocks are unstable at surface conditions and are therefore prone to chemical transformation. Weathering generates the mineral fraction of soils, making life possible on the Earth's surface. This paper focuses on the role of water, air and vegetation in weathering reactions. The most important are hydrolysis and oxidation-reduction reactions. Finally, as a didactic resource, we suggest some ideas for laboratory.
