Minerals ( Read ) | Earth Science

Coal is made of plant and animal remains. Is it a mineral? Coal is a classified as a sedimentary rock, but is not a mineral. Naturally Occurring. Minerals are made by natural processes, those that occur in or on Earth. A diamond created deep in Earth's crust is a mineral, but a diamond made in a laboratory by humans is not.
