(5) Characteristics of Minerals

• Solid- always solid, not a liquid or gas. It has
  a definite volume and a definite shape
• Ex._________________ Non-ex.____________

41
(5) Characteristics of Minerals

• Crystalline Structure- particles must line up in
  a pattern that repeats over and over again
• Ex.______________ Non-ex._____________

42
Crystals

• Crystals are solid, geometric forms produced by a
  repeating pattern of atoms or molecules that are
  present throughout the mineral.
• A crystals shape is determined by the
  arrangement of the atoms or molecules within the
  crystal.
• All minerals can be grouped into crystal classes
  according to the kinds of crystals they form.
