| Nice Speedo Alien! On earth geogolists use Luster, Hardness, Streak, Density and Cleavage or Fracture to identify minerals | |

| Human Boy, that sounds complicated | |
| | |
|
|
| | |
| It's not....Just follow along. Luster is the shine or reflectiveness of a mineral. Hardness is a measure of a minerals ability to resist scratching. Density is a measure of mass per unit of volume. | |

| Streak is the color or powder a mineral leaves after rubbing on an unglazed porcelain streak plate and Cleavage is how a mineral splits along planes...........Very Simple? | |
