Chemical weathering involves the breaking down of rocks by chemical reactions. The three main chemical reactions that decompose rocks are acid reactions, oxidation and hydrolysis. Natural Chemical Weathering Acid-producing lichen and tree roots that eat through rock are natural sources of chemical weathering. Many minerals are also relatively unstable and deteriorate in the presence of water and natural chemicals. acid reaction oxidation hydrolysis limestone cave immersed rocks rust acid reaction oxidation hydrolysis chemical weathering (hydrolysis) granite lichen tree roots clay Chemical Weathering & Pollution Chemical weathering can be caused by pollution. Acid rain, created by the burning of fossil fuels, dissolves some types of rocks such as limestone. effects of acid rain The feldspar found in granite breaks down into clay.
