| Question | Answer |
|---|---|
| What is cleavage? | Cleavage is the property of splitting evenly along flat surfaces. |
| What is streak? | Streak is the color of a mineral's powder. |
| What is luster? | Luster is how a mineral reflects light from its surface. |
| What is a compound? | A compound is two or more elements chemically joined. |
| What is fluorescence? | Fluorescence the property of glowing under ultraviolet light |
| What is fracture? | Fracture is how a mineral breaks apart when it does not split evenly. |
| What is Mohs hardness scale? | Mohs hardness scale is a ranking of minerals from softest to hardest. |
| What are crystals? | Crystals are the repeating pattern of a mineral's particles in a solid. |
