WebRocks at the surface undergo mechanical and chemical weathering. These physical and chemical processes break the rock into smaller pieces. Physical weathering breaks the rocks apart, while chemical weathering dissolves the less stable minerals. These original elements of the minerals end up in solution, and new minerals may form. WebVolcanic ash and lava undergo chemical weathering much faster when newly erupted. This results in a change in their own chemical composition, often leading to the eventual release of dissolved elements into the ocean. It is thought that this process causes the ocean to draw CO2 out of the atmosphere, thereby cooling the planet.
