| what does inorganic mean | it was never alive |
| what are some inorganic things | minerals, rocks, water |
| what are some things that are not inorganic | coal, trees, fossils, peals ,bones |

| native elements characteristics | gold (Au) diamond(c) silver(Ag) |
| how do minerals form | cooling of magma |
| why does some minerals have no crystals | magma was fast cooling |
| why does some minerals have SMALL CRYSTALS | medium cooling magma |
| why does some minerals have LARGE CRYSTALS | Slow cooling magma |

| how do you test mineral hardness | seeing if the mineral can scratch glass finger nail copper penny etc |
| what is breakage | the way the mineral breaks either cleavage or fracture |
| Cleavage | minerals break smoothly smooth surfaces and angles flat surfaces |
| fracture | minerals that break jaggedly and rough edges |
