</em>
<em></em>
<u>Explanation:</u>
There are different physical features of a mineral that are used in the identification of species of fossils. The characteristics may include hardness, Fracture, tenacity, and, cleavage. The cleavage, therefore, occurs as a result of the strengthening of the weaker bonds and the greater lattice spacing that exist in the plane. The lattice accompanies the more fragile relationship along with the place because the link cannot maintain interatomic spacing.
The property of cleavage and positioning of fracture derived from structural species of the crystals.
