| Crystal | Solid in which atoms are arranged in repeating patterns |
| Fracture | When a mineral breaks into pieces with arclike rough or jagged edges |
| Gem | Rare precious highly prized mineral that can be cut polished and used for jewelry |
| Hardness | measure of how easily a mineral can be scratched which is determined by the arrangement of a minerals atoms |
| Luster | The way that a mineral reflects light from its surface two types of metallic and nonmetallic |
| Mineral | Naturally occurring inorganic solid with a specific chemical composition and a definite crystalline structure |
| Silicate | Mineral that contains silicon oxygen and usually one or more other elements |

| Fractional crystallization | Processes in which different minerals crystallize from magma at different temperatures are moving elements from magma |
| Granitic rock | White colored interested igneous rock that has high silica content |
| Igneous rock | Intrusive or extras of rock forms from the cooling and crystallization of magma or lava |
| Intrusive rock | coarse grained igneous rock that is formed when molten rock cools slowly and solidifies inside earths crust |
| Kimberlite | Rare ultramafic rock that can contain diamonds and other minerals formed on the under very high pressures |
| Lava | Magma that flows out onto earths surface |
| Partial melting | Process in which different minerals melt into magma different temperatures changing its composition |
| Pegmatite | Igneous rock with extremely large gray and minerals that can contain rare ores such as lithium and beryllium |
