| Crystallization | Process by which a mineral grows |
| Diamond | Mineral with the hardness of 10 |
| Fracture | Mineral breaks rough, uneven or bumpy |
| Cleavage | Mineral breaks evenly in smooth flat surfaces |
| Streak | Powder produced when a mineral is ground up |
| Talc | The softest mineral with a hardness of 1 |
| Quartz | The most abundant silicate mineral on the earth |
| Silicates | Rock forming minerals containing silicon and oxygen |
| Color | The least relicable of test used to identify minerals |
| Luster | The way the surface of mineral reflects light |
| Specific Gravity | The density of a mineral compared with the density of water |
| Rocks | An aggregate (combination) of one or more minerals |
| Three rock types | Igneous, Sedimentary, Metamorphic |
| Intrusive rock | Igneous rock with large coarse crystal grains |
| Limestone | Formed organically from seashells |
| Rocks containing fossils | Sedimentary Rock |
| Metamorphic Rock | Rocks formed from existing rock through heat, pressure, and chemical reactions |
| Igneous Rock | Rock formed when molten rock cools and hardens |
| Rock Cycle | The continuous process in which rocks change from one type to another |
| Extrusive Rocks | Rocks that form as magma cools quickly as it leaves volcanoes. |
| Granite | One of the most common intrusive rocks |
| Shale | Most commone sedimentary rock and indicates places where ancient seas covered the land |
| Melting | Process by which rock becomes magma |
| Weathering and Erosion | Processes by which Clastic Rock forms |
| Volcano or Rift | Geological phenomena most likely to produce igneous rocks |
