Because of the mini cracks and uneven surfaces
Explanation:
These ridges exert a normal contact force opposite to the motion.

Answer:
Friction is the force that arises as a result of the minute deformations on the two surfaces in contact. Due to these deformations and roughness, the surfaces stick together, and hence relative motion between them is reduced. Thus, friction opposes relative motion. between two surfaces due to their molecular adhesion (the force that is present when two molecules are brought close) and the roughness.
