Which are the main causes of crack growth in rocks over time?

The process in nature that breaks down rocks is called physical weathering. Physical forces such as abrasion, frost action, salt crystal growth, thawing, freezing and temperature fluctuation weaken rocks and cause them to crack and disintegrate over time.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
