Document Summary
Mineral any naturally occurring inorganic solid that possesses an orderly crystalline structure and a definite chemical composition that allows for some variation. Minerals exhibit 5 characteristics: naturally occurring, generally inorganic, solid substance, orderly crystalline structure, define chemical composition that allows for some variation. A rock is any solid mass of mineral, or mineral-like, matter that occurs naturally as part of our planet. Most rocks are aggregates of several different minerals. Some rocks are composed of nonmineral materials like volcanic rocks obsidian and pumice: quartz, semi-precious gem, used for making glass, glass is not mineral, used for precision instruments, mica, windows. Insulators on electronics: sparkle, copper ones, plumbing, electronic wires, much more. A rock is made of 2 or more minerals (can be the same mineral) minerals are the building blocks of rock. How do minerals form: precipitation of mineral matter from a solution. Water solution containing dissolved material matter: solidification of crystallization of molten rock.
