| Question | Answer |
|---|---|
| 1. Properties of Matter | Naturally occurring: Created by nature. |
| Inorganic: | Cannot be created using any living thing, only NON-living. |
| Solid: | Minerals have a definite volume, and shape |
| Crystal Structure: | particles of a mineral lines up in a pattern over and over again |
| Definite chemical composition: | A mineral has definite chemical make-up of certain elements. |
| 2. Identifying Minerals: | Mohs hardness scale: Identifies hardness from softest to hardest of ten minerals. |
