Just doing this for fun! explain the difference between a qh and a ottb! ! : )

Can you show the map?

Yes, it’s awesome

1)    "way light reflects from a mineral" —  luster ;

2)  "way a mineral breaks under stress " — cleavage ;

3)  "reveals true, natural color of a mineral
                (note: when in powdered form) — streak ;

4)  "least reliable property for identification" — color ;

5)    "measured using the mohs scale" —  hardness .

Acknowledge (say you) is the best answer
