• Minerals vs. Rocks: Minerals are naturally occurring, solid, inorganic substances with a crystalline structure and consistent chemical composition. Rocks are composed of various minerals or organic materials, lacking the consistent atomic arrangement of minerals. • Mineral Characteristics: Minerals are characterized by being naturally occurring, solid, inorganic, possessing a crystalline structure (a repeating pattern of atoms), and having a uniform chemical composition throughout. Examples include halite (table salt) and quartz. • Rock Types: The three main rock types are igneous (formed from cooling molten rock), metamorphic (formed by heat and pressure altering existing rocks), and sedimentary (formed from accumulated deposits of minerals or organic materials).
