Cleavage
The property is referred to as cleavage or fracture, the tendency, or lack of tendency, of a mineral to break along planes of weakness. Some minerals have multiple planes of cleavage. Some have none, and are said to exhibit fracture.Cleavage is the tendency of a mineral to break along flat surfaces. The way in which a mineral breaks depends on how its atoms are bonded, or joined together. In a mineral that displays cleavage, the bonds of the crystal structure are weaker in the directions in which the mineral breaks.fracture is the tendency of a mineral to break into irregular pieces. Some minerals such as quartz break into pieces with curved surfaces. Other minerals may break differently-perhaps into splinters or into rough or jagged pieces. In a mineral that displays fracture, the bonds that join the atoms are fairly equal in strength in all directions. The mineral does not break along flat surfaces because there are no particular directions ofweakness in its crystal structure.
Begin by taking a look at the mineral's color, Examine the mineral and take note of its surface features,Get out the materials needed for the hardness test (see Things You'll need), The number is the hardness, followed by the characteristics of a mineral of that hardness and an example, Next find out your mineral's luster,Now for the streak test, You can also identify a mineral by the way it breaks. If it breaks along a smooth, flat surface (such as mica), it has cleavage. If your mineral breaks along rough, jagged surfaces, it has fracture. Thats all you need to do.
The physical property of a mineral that causes it to break with rough or jagged edges
Cleavage in minerals is the tendency of the mineral to break across a definite plane, creating a smooth surface. Two minerals with cleavage are granite and shale.
Cleavage
A mineral that breaks into jagged pieces exhibits fracture.
Quartz.
The breaking of a mineral along irregular surfaces is called a fracture. The splitting of a mineral along smooth, flat surfaces is called cleavage.

Cleavage is when you can break the rock into square like pieces and Fracture is when you break a rock into uneven different shaped pieces.
A mineral breaks in two ways: cleavage (a definite straight and even break) and fracture (jagged and unpredictable)
