| Mineral | Naturally occurring, inorganic solid with a definite crystalline structure. |
| Diamond | Mineral with the hardness of 10 |
| Fracture | Mineral breaks rough, uneven or bumpy |
| Cleavage | Mineral breaks evenly in smooth flat surfaces |
| Streak | Color of the mineral in powder form. |
| Talc | The softest mineral with a hardness of 1 |
| Silicates | Rock forming minerals containing silicon and oxygen |
| Color | The least reliable of test used to identify minerals |
| Luster | The way the surface of mineral reflects light |
| Rocks | Naturally occurring organic solid made of 1 or more minerals. |
| Three rock types | Igneous, Sedimentary, Metamorphic |
| Intrusive rock | Igneous rock with large mineral grains |
| Organic Sedimentary | Rock containing fossils |
| Metamorphic Rock | Rocks formed from existing rock through heat & pressure. |
| 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 lava cools quickly as it leaves volcanoes. |
| Melting | Process by which rock becomes magma |
| Weathering and Erosion | Processes by which sediments are formed. |
| Foliated metamorphic | Rock with visible layers of minerals. |
