Physical … 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.
