 I’m the color of the mineral powder
left behind when a mineral is scraped
           across a surface.

             nstreak
I’m molten rock inside Earth


               n   Magma
 I’m a solid formed in nature with a
definite chemical makeup and crystal
               structure.

          nMineral
I’m the way in which light reflects
  from the surface of a mineral.


             nLuster
I’m the molten rock that reaches
        Earth’s surface.
          n Lava
I’m a substance that contains only
        one type of atom.

         nElement
I’m the tendency of a mineral to
   break along flat surfaces.

         nCleavage
I’m a solid in which the atoms are
 arranged in an orderly, repeating
    three-dimensional pattern.

             nCrystal
I’m the tendency of a mineral to
   break into irregular pieces.


     nFracture
I’m a mineral’s resistance to being
           scratched.

      nhardness
I’m the mass of a substance divided
          by its volume.
