which statement INCORRECTLY describes the type of physical change in a mineral

Fractures in a mineral are geometrical in shape
cleavage of a mineral produces uniform shapes,
Cleavage in a mineral breaks along curved surfaces and weal areas
Fractures of a mineral break parallel to weak areas

Cleavage in a mineral breaks along curved surfaces and weak areas is the statement that INCORRECTLY describes the type of physical change in a mineral. Cleavage actually produces flat, smooth surfaces.
