| Four properties of a mineral | solid, inorganic, naturally made, crystalline structure |
| Luster | The way a mineral reflects light |
| Hardness | A mineral's ability to resist scratching |
| How to determine a mineral's hardness | Rub the mineral across unglazed ceramic |
| Cleavage | allows minerals to break along smooth, flat lines |
| Examples of NON minerals | teeth, coal, paper, honey |
| If a mineral is harder than quartz, then... | it will scratch quartz. |
| Moh's Scale | A scale from 1-10 that measures mineral hardness and what will scratch a mineral |
| Fracture | allows minerals to break along rough, jagged lines |
| Silicate Minerals | Minerals that contain silicon and oxygen |
| Hardest Mineral on Moh's Hardness Scale | Diamond |
| Types of Mineral Luster | Metallic & Nonmetallic |
| Most reliable property of minerals | Streak |
