difference between minerals and rocks
What's the difference between rocks and minerals?[edit] A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids. Some rocks are predominantly composed of just one mineral.
While minerals are pure and made of the same substance, rocks are not. Some minerals have crystals and are pretty, but rocks do not form single crystals and are rarely pretty. While minerals have a definite shape and a single color, rocks do not have a single shape and are usually made up of different colors.
