Halite crystals break into smaller crystals of the same shape due to the crystal structure and cleavage of the mineral. Halite has a cubic crystal structure and perfect cubic cleavage, which means it breaks along planes that are parallel to the faces of the cube, resulting in smaller crystals with the same cubic shape.
A mineral can have varying numbers of cleavage planes, areas where there exists an inclination to cleave when struck or force is applied.. Most mineral crystals exhibit a preferred cleavage in certain directions, but may have cleavage planes in other directions.
Cleavage. Minerals with cleavage break along specific planes, resulting in smooth and flat surfaces. The number and angle of cleavage planes depend on the mineral's atomic structure.
The cleavage of a shale rock refers to its tendency to break along flat, parallel planes due to its layered structure. This cleavage planes are a result of the alignment of clay minerals within the rock, allowing it to split easily along these planes. Cleavage in shale rocks can enhance its ability to split into thin sheets or slabs.
In order to exhibit cleavage planes, all minerals must have a crystalline structure.
Cleavage of crystals is anisotropic because the structure of crystals consists of planes of atoms where the bonds are weaker or stronger in different directions. When a crystal cleaves, it breaks along planes of weaker bonds, resulting in different cleavage planes having different strengths. This anisotropy arises from the crystalline structure and the arrangement of atoms in the crystal lattice.
Cobalt has a cleavage in three directions, forming a cube.

Gold does not have a cleavage it has a fracture: The type of fracture is hackly or jagged. Cleavage usually relates to crystals (although cleaving crystals can also be made to fracture too).
The rocks tend to spilt along parallel planes defined by distribution and parallel arrangment of platy mineral crystals.
it has cubic cleavage, means perfect in {100}, {010}, {001} planes.
Chalcopyrite does not have cleavage. It typically exhibits a conchoidal fracture instead of cleavage planes.
A mineral can have varying numbers of cleavage planes, areas where there exists an inclination to cleave when struck or force is applied.. Most mineral crystals exhibit a preferred cleavage in certain directions, but may have cleavage planes in other directions.
Parallel lines seen on cleavage planes or crystal faces are usually caused by twinning, where two crystals grow together with a specific orientation relationship. This twinning can result in repeated patterns of parallel lines that are visible on the surface of the crystal.
Olivine does not have cleavage. It exhibits a granular or irregular fracture pattern instead of cleavage planes.
Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.
