Natural Rock Weathering. As rain falls through the atmosphere, it combines with CO 2 to form carbonic acid.. When this dilute acid falls on mountains, forests and grassland, the CO 2 interacts with rocks and soil, mineralises and is safely stored in solid carbonate form.. The natural process of weathering already accounts for the removal of 1 billion tonnes of CO …
