Mineral Classification, An Organizational Necessity

Minerals form under a variety of conditions: the cooling of lava or liquid solutions, the evaporation of mineral-rich water and at high temperatures and pressures found in the core of the earth. They have a solid, crystalline structure, and are arranged in geometric patterns at the atomic level.
