GEOLOGY

Detailed explanation-1: -Explanation: Cleavage is defined as the tendency of a crystallized mineral to break along certain directions yielding more or less smooth, plane surfaces. In other words, cleavage are the planes easiest fractures and are essentially indicative of directions of least cohesion.

Detailed explanation-2: -Cleavage is the tendency of minerals to split along crystallographic planes as a result of structural locations of atoms and ions in the crystal, creating planes of relative weakness.

Detailed explanation-3: -Cleavage-The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice.

Detailed explanation-4: -cleavage, tendency of a crystalline substance to split into fragments bounded by plane surfaces. Although cleavage surfaces are seldom as flat as crystal faces, the angles between them are highly characteristic and valuable in identifying a crystalline material.

Detailed explanation-5: -Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism. The degree of deformation and metamorphism along with rock type determines the kind of cleavage feature that develops.
