This is termed fracture, eg. the conchoidal fracture of obsidian. Breaking into pieces with straight lines and flat faces is called cleavage; minerals like calcite and fluorite exhibit excellent cleavage.
Cleavage is the tendency of a mineral to break along flat surfaces and fracture is the tendency of a mineral to break into irregular pieces.

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.
Cleavage and fracture describe how a mineral breaks. Cleavage shows the tendency of a mineral to break along specific planes due to its crystal structure, while fracture refers to irregular breakage patterns. Cleavage can create smooth surfaces, aiding in mineral identification and classification, while fractures can vary in appearance, from conchoidal (shell-like) to uneven.

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.
The tendency of some minerals to break unevenly along curved or irregular surfaces is called cleavage. Cleavage is a property that describes how a mineral breaks when subjected to stress, and it is determined by the internal arrangement of atoms within the mineral's structure.
Fracture in minerals refers to the way a mineral breaks when it is not subjected to cleavage. It can result in irregular, jagged surfaces or smooth, curved surfaces. This property helps in identifying minerals based on how they break.

Cleavage is the property that examines a mineral's ability to break into even pieces along specific planes or directions. Minerals with good cleavage will break cleanly and smoothly along these planes, while minerals with poor cleavage will break in irregular or jagged shapes. Cleavage is determined by the internal atomic structure of a mineral.
