Rock Vs Mineral

Minerals are made up of ONE thing. Like this blue 8 studded LEGO piece. If there were more of the same pieces stuck together, it would still be a mineral.

Below is Quartz, a single mineral. Below that is Biotite Mica, another mineral.

Rocks are made up of TWO or more different minerals put together. Like these LEGO pieces are demonstrating there is more than one type of LEGO piece in this build.

The rock below shows the two minerals Quartz and Biotite together.
