A mineral is described as a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.
Minerals are naturally occurring They are not made by humans
Minerals are inorganic They have never been alive and are not made up from plants or animals
Minerals are solids They are not liquids (like water), or gases (like the air around you)
Minerals have a definite chemical composition Each one is made of a particular mix of chemical elements
Minerals have an ordered atomic arrangement The chemical elements that make up each mineral are arranged in a particular way - this is why minerals 'grow' as crystals
