Plants can physically break apart rocks when they grow in cracks. When plants and animals decompose, they become mostly carbon dioxide. While carbon dioxide dissolved in rain makes the water slightly acidic, soil water is much more acidic due to the carbon dioxide provided by decaying plants and the respiration of soil organisms.
