What differentiates cleavage from fracture?
What will be an ideal response?
Cleavage is a natural break along a plane of weak bonding within a mineral's crystal structure. Cleavage will result in smaller pieces of the mineral, all with the same geometry as the original crystal. Fracture is a break that results from a mineral having relatively equal strength bonds in all directions that make up its crystal form. Consequently, all the products of fracture are different and irregular or conchoidal shapes.
