7 Minerals Mineral means “a soild inorganic substance of natural occurrence”

8 How its formed   The caves are filled with water and dissolved minerals permeated through the rock.  With time these minerals will crystallize in the caves, and line the cave with a silica layer (amethyst).  The geodes continue developing as long as there is moisture present. “Permeated” means “spread throughout”

9 Fun Fact The Greek word “amethystos” is translated as ”not drunken”. Amethyst was thought to be a strong antidote against drunkeness, which is why wine goblets were often caved from it.
