Most of the people usually don't know the difference between a mineral and a rock. A mineral is a naturally occurring solid that has a chemical composition and formed through geological processes. A rock, however, is made up of one or more minerals. Take up this Earth science unit 2 quiz on rocks and minerals to see just how much you understand.
