WebChemical weathering of rocks is a spontaneous (i.e., irreversible) thermodynamic process leading to a more stable state for natural materials under a given set of conditions (e.g., temperature and pressure). It results from the reaction of aqueous, acidic, and oxidizing solutions with the minerals in rocks and soils. WebPhysical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves.
