| A mineral that is made up of only one element | Native Element |
| Minerals that break at random and with rough or jagged edges | Fracture |
| Most common mineral found in the Earth's crust | Quartz |
| Color, Crystal, Cleavage/Fracture, Luster, Hardness, Streak | Mineral Properties |
| Shape of mineral formed by repeating pattern of atoms. Some mineral have well defined crystals (cube, hexagon, etc.) while others are irregular | Crystal |
| A mineral lacking both oxygen and silicon | Non-Silicates |
| A substance that cannot be broken down into simpler substances by chemical means | Element |
| The way the mineral breaks. Minerals break away along smooth, flat surfaces and every fragment has the same general shape. | Cleavage |
| The color of the streak can be different from the mineral. The color of the powdered form of the mineral. Minerals must be softer than the streak plate. | Streak |
| The number of protons equals electrons | Atomic Number |
| The ore is mined from rocks that have not been exposed too weathering in a tropical environment | Bauxite/Aluminum |
| Scale from 1 (softest) to 10 (hardest). Test by seeing if the mineral can scratch different objects. | MOHS Hardness Scale |
| How easily a mineral can be scratched | Hardness |
| A mineral containing both silicon and oxygen | Silicates |
| Surface reflection | Luster |
| Shiny, like metal | Metallic |
| Least reliable test. Many minerals have the same _____. | Color |
| A naturally occurring inorganic solid, with a crystal shape that repeats itself, and a definite chemical composition (elements are always the same) | Mineral |
| A rock that contains high enough concentrations of a defined substance such as metal, so it can mined for profit. | Ore |
| Most abundant metallic mineral | Iron |
| Dull, non-shiny, surfaced | Non-Metallic |
| Most abundant elements in Earth's crust | Silicon, Oxygen |
| Mass/Volume | Density |
| Naturally formed, inorganic, crystal-like structure, solid structure, specific chemical composition | Mineral |
| All minerals are solids. A solid matter with tightly packed atoms or ions that has a definite shape and volume. | Solid |
