Weathering is the mechanical or chemical process by which rocks are broken down the weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie. As the temperature increases, so does the rate of chemical reaction this is because heat energy causes more collisions, with more energy, between the enzyme molecules and other molecules.
