The tendency of a stone is, to split along: A. Texture B. Fracture C. Cleavage D. Structure

The correct answer is C. Cleavage.

Cleavage is the tendency of a mineral to break along flat, smooth surfaces. It is caused by the way the atoms in the mineral are arranged. Minerals with perfect cleavage can be split into thin sheets.

Texture is the overall appearance of a rock, including its grain size, color, and shape.

Fracture is the way a rock breaks when it is not along a cleavage plane. It can be either smooth or rough, depending on the type of rock.

Structure is the arrangement of the minerals in a rock. It can be either igneous, sedimentary, or metamorphic.
