Mineral- a naturally occurring, inorganic solid that has a crustal structure and a definite chemical composition
Rock- a large mass of stone
Organic- derived from living organisms
Inorganic- not derived from living organisms
Pure Substance- a form of matter that has a constant chemical composition and characteristic properties. It cannot be separated into its several components without breaking its chemical bonds.
Element- a substance composed of a single kind of atom
Molecule- the smallest physical unit of an element or compound, consisting of one or more like atoms in a element and two of more different atoms in a compound
Compound- a substance in which two or more elements are chemically joined
Mixture- any combination or blend of different elements, kinds, qualities, etc
Solution- a mixture in which one substance is dissolved in another
Mohs Scale- a scale ranking ten minerals from softest to hardest; used in testing the hardness of minerals
Streak- the color of a mineral’s powder
Luster- the way a mineral reflects light from it’s surface
Cleavage- a minerals ability to split easily along flat surfaces
Fracture- the way a mineral looks when it breaks apart in an irregular way
Vein- a narrow slab of mineral that is sharply different from the surrounding rock
Gemstone- a hard, colorful mineral that has a brilliant or glassy luster
Ore- rock that contains a mineral or economically useful mineral
Smelting- the process in which ore in melted to separate the useful metal from other elements
Alloy- a solid mixture of two or more minerals
