Cleavage
Cleavage
This property is called cleavage.

Fracture
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
Cleavage is the tendency of some minerals to fracture or break alongflat three dimensional planes. The surfaces are usually smooth to the touch.
It would be important because cleavage is a tendency of some minerals to break along smooth, flat surfaces.
The special property that magnetite displays is that it is attracted by a magnet. Cleavage is the mineral property that explains why some minerals break along smooth, flat surfaces.
minerals with cleavage break along smooth, flat surfaces in one or more directions.
Cleavage is the splitting of rocks or minerals along defined surfaces.
Slate is a sedimentary rock that can be split horizontally to produce smooth flat surfaces that is often used as a roofing material.
The breaking of a mineral along irregular surfaces is called a fracture. The splitting of a mineral along smooth, flat surfaces is called cleavage.
