It means that the chemical bonds of the mineral aren't too strong along the lines and that when you break the mineral it'll break along those lines.

The internal atomic structure of a mineral determines whether it wil show cleavage or break in irregular fractures. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral can be said to have cleavage.
By breaking it and observing if the breakage is along planes of weakness that naturally occur in its crystals. The number of, and angles of, these cleavage planes in a specimen, are one identifying characteristic of a mineral.
Cleavage - Property of minerals that break along smooth, flat surfaces.
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.
minerals with cleavage break along smooth, flat surfaces in one or more directions.
Cleavage planes occur due to a weakness or propensity to fracture in a crystalline structure.

Apatite is a mineral that comes is blues, greens, browns, yellows and clear. It has a weak cleavage and a choncoidal fracture.
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 the breaking of a mineral along flat surfaces. Fracture, on the hand is just the chipping or "fracture" of a mineral.Cleavage is the tendency to break along flat surfaces, and fracture is the tendency of a mineral to break into irregular pieces.
Of all the minerals, the micas have some of the most prominent cleavage planes. Muscovite and biotite, for example, have perfect cleavage in one plane that allows you to actual peel layers of the mineral off in very thin sheets.

The internal atomic structure.
Cleavage and fracture are determined by atomic structure and the relative weakness or strengths of the atomic bonds.

Cleavage- in geolohy, the tendency of a mineral to splitalong specific planes of weakness to format smooth flatSurface.Fracture- the manner in which a mineral breaks alongeither curved or irregular
the manner in which a mineral breaks along either curved or irregular surfaces is called a FRACTURE.
Cleavage is when a mineral breaks into flat pieces. Fracture is when a mineral breaks into irregular pieces. Topaz atom bonds are weaker in some parts and stronger in others. When it is equally strong then it breaks into irregular pieces and if it all weak in a flat line then it will be flat.
