It is a fault line, or fissure, along which it may be split.
When a crystal is broken, the way it breaks is called its cleavage. Cleavage is the way the crystal naturally breaks along planes of weakness due to its internal atomic structure.
Obsidian does not have cleavage because of the way it forms. Obsidian is essentially nature's form of glass and so it has no regular or patterned crystal structure. Without that crystal structure, there is no cleavage.
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.
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.
Halite is a cleavage because it splits evenly, but fracture would mean it breaks irregularly.
All minerals have a crystal form, but not all have cleavage.
cleavage surface are smooth and shiny as the fracture is due to weakness in the bonds between the atoms rather than a breakage. Crystal face is where the crystal development such as twinning take place.

i think crystal habit is the minerals structure, while cleavage is the patter it breaks into.
Cleavage surfaces will be smooth, flat, and exhibit specific patterns of breakage, depending on the mineral's cleavage plane. Crystal surfaces, on the other hand, will display the crystal shape and characteristic geometric patterns unique to that mineral. Crystal surfaces can also sometimes show growth lines or striations indicating the crystal's formation process.
Yes. Quartz can have very well-formed crystals but lacks cleavage.
Obsidian does not have cleavage because of the way it forms. Obsidian is essentially nature's form of glass and so it has no regular or patterned crystal structure. Without that crystal structure, there is no cleavage.
Crystal form refers to the external geometric shape of a mineral, which is determined by its internal atomic arrangement. Cleavage, on the other hand, is the way a mineral breaks along specific planes due to its weak bonds in certain directions. Cleavage is a physical property, while crystal form is a visual characteristic.
Muscovite has perfect basal cleavage, or book cleavage.
Cleavage is related to the minerals atomic structure because minerals are arranged in crystal lattices . It's the shape of these lattices that determine the mineral's cleavage.
