They consider the breakdown of rock into smaller and smaller pieces through processes that collectively are known as weathering. ... In nature, abrasion occurs as wind and water rush over rocks, causing them to bump against one another and changing their shapes. Rocks become smoother as rough and jagged edges break off.
Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers. Hydrolysis reactions break bonds and release energy.
