GEOLOGY

Detailed explanation-1: -Crystals are classified into seven crystallographic systems based on their symmetry: isometric, trigonal, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic.

Detailed explanation-2: -Crystal Systems and Silicate Structures All minerals can be divided into one of seven crystal systems: triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, cubic, and rhombohedral. These systems are established at the atomic level of the mineral’s crystal structure.

Detailed explanation-3: -There are 7 crystals systems and they are named: Triclinic, Monoclinic, Orthorhombic, Tetragonal, Trigonal, Hexagonal, and Cubic.

Detailed explanation-4: -Based on their point groups crystals and space groups are divided into seven crystal systems. The Seven Crystal Systems is an approach for classification depending upon their lattice and atomic structure. The atomic lattice is a series of atoms that are organized in a symmetrical pattern.
