MINERALS

Naturally occurring Crystalline structure Inorganic Chemical composition

is a unique arrangement of atoms, ions or molecules in a crystalline liquid or solid. It describes a highly ordered structure, occurring due to the intrinsic nature of its constituents to form symmetric patterns

existing in nature and without artificial aid

Inorganic compounds are traditionally viewed as being synthesized by the agency of geological systems

MAGMA -As the magma moves closer to the

Earth's crust it begins to cool.  As it cools the atoms inside the magma condense, moving closer together until it solidifies and forms crystals.

Fast Cooling = Small Crystals Slow Cooling = Large Crystals 

EVAPORATION OF WATER -Some minerals form when water

containing dissolved substances evaporates.  When the water evaporates it leaves behind the substances that were dissolved inside it.
