Hydrolysis occurs when water reacts with minerals in the rock and changes the chemical composition of the rock. This change weakens the rock and makes it more susceptible to breaking down. Carbonation occurs when carbon dioxide (CO 2) from moisture in the air reacts with carbonate minerals. Carbonic acid can break down rocks when combined with water.

Without that mineral to react with water and consume oxygen, the gas was finally allowed to accumulate. Oceans eventually became saturated, and oxygen crossed into the atmosphere. It really appears to have been the starting point for life diversification as we know it, Smit said.
Chemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions. Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment.

Chemical weathering occurs when rocks undergo chemical reactions to form new minerals. Water, acids, and oxygen are just a few of the chemicals that lead to geological change. Over time, chemical weathering can produce dramatic results.
Most rocks are composed of minerals. Minerals are defined by geologists as naturally occurring inorganic solids that have a crystalline structure and a distinct chemical composition. Of course, the minerals found in the Earth's rocks are produced by a variety of different arrangements of chemical elements.
