19. Who am I? I come in two colors. But both colors have the same color streak. My streak is red/brown. I’m named for my blood-red color. HEMATITE

20. Who am I? I am a polymorph. A Diamond!! I am made of pure carbon I form under extreme heat and pressure. I have a hardness of 10 on the Mohs scale I am very valuable Other form? graphite

21. Who am I? I am composed of 3 or 4 minerals. The rock: GRANITE I am usually pink in color, though I can be gray, green or black depending on what minerals I have in me. I have large crystals that are easily seen. My minerals cool at different rates.

22. Who am I? I am the largest group of all the minerals. SILICATES I make up 90% of all the rocks in earth. I am made of basically 2 elements I am formed from silicon-oxygen tetrahedrons.

23. I can scratch a coin, but a steel knife can scratch me. My hardness is……
