Minerals Shaping our Crust Minerals 5 Characteristics Solid Solids Solids have definite shapes & volumes Liquids & gases … Able to expand & contract easily volume changes along w/ their density Therefore: density can ID a mineral Minerals 5 Characteristics Solid Inorganic Naturally Occurring Naturally Occurring/ Inorganic Formed by natural processes Inorganic: can never have been living Non-Ex/ Coal, Sugar Lab made rocks are NOT minerals Ex/ industrial diamonds Minerals 5 Characteristics Solid Inorganic Naturally Occurring Definite Crystal Structure Specific Composition Definite Crystal Sructure Crystals: solids w/ atoms arranged in repeating patterns. The formation and size of crystals depend on the environment they formed in. Specific Chemical Composition Most minerals made of compounds Few are made of one element Ex/ Diamond (C), Gold (Au), Sulfur (S), etc. Quartz Combination of Silicon (Si) and Oxygen (O), or SiO4 The amount and arrangement of these elements are unique to quartz
