Cleavage and fracture describe how a mineral breaks. Cleavage shows the tendency of a mineral to break along specific planes due to its crystal structure, while fracture refers to irregular breakage patterns. Cleavage can create smooth surfaces, aiding in mineral identification and classification, while fractures can vary in appearance, from conchoidal (shell-like) to uneven.
