Calcite exhibits cleavage in three directions.
A mineral that splits evenly along flat surfaces is said to have a cleavage fracture. Cleavage occurs when a mineral breaks along weak atomic planes due to the internal atomic structure and bonding of the mineral.
The name of a mineral that splits along flat surfaces is called mica. Mica's cleavage planes allow it to be easily split into thin sheets.

It exhibits cleavage, which is the tendency of a mineral to break along certain planes of weakness determined by its atomic structure. Cleavage is a property seen in minerals with strong bonds in certain directions but weaker bonds in other directions. The resulting flat, shiny surfaces are a result of the breakage along these weakly bonded planes.
The term is called CLEAVAGE. It is a special form of Foliation in rock metamorphism.

An example of a mineral that splits in three directions is fluorite. Fluorite exhibits perfect octahedral cleavage, allowing it to break along three distinct planes at angles of 90 degrees to each other. This characteristic gives fluorite its typical cubic shape in its crystal form. Other minerals that share similar cleavage properties include halite and galena.
To test cleavage in a mineral, you can use a sharp tool, like a knife or a fingernail, to apply pressure on the mineral's surface along its natural planes of weakness. When the mineral splits, observe whether it breaks smoothly along these planes, indicating cleavage. The quality of the cleavage can be assessed by examining the flatness and angularity of the resulting surfaces, as well as how easily the mineral splits. Different minerals exhibit different cleavage patterns, which can help in their identification.

The ability of a mineral to break along preferred directions is called cleavage. Cleavage is a result of the arrangement of atoms within the mineral structure, which causes it to break in certain directions more easily than others.
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.
To determine if a mineral has cleavage or fracture, observe how it breaks. Cleavage is characterized by smooth, planar surfaces along specific directions where the mineral splits easily, reflecting its internal atomic structure. In contrast, fracture results in irregular, jagged surfaces without defined planes. Testing a mineral's breakage pattern can help you identify its cleavage or fracture nature.
