 What are 5 properties for identifying minerals? | color, luster, streak, hardness, cleaveage/fracture |
| Name 6 ways to describe luster | dull, shiny, transparent, translucent, metallic, vitreous |
| Dull | a non-reflective surface |
| Shiny | a surface that reflects light |
| Transparent | you can see through the mineral |
| Tranlucent | light goes through the mineral but you can't see through it |
| Metallic | Very shiny. Looks like metal. |
| Vitreous | Looks like glass |
| How do you test a mineral's hardness? | By scratching a mineral. A mineral can only be scratched by a mineral that's harder than it |
| What's the difference between cleavage and fracture | Cleavage - breaks with clean and flat surface Fracture - breaks with rough uneven surface |
| List Mohns Hardness Scale minerals in order | 1. Talc 2. Gypsum 3. Calcite 4 Fluorite 5. Apatite 6. Orthoclase 7. Quartz 8. Topaz 9. Corundum 10. Diamond |
