Consider the statements regarding the internal structure of minerals

  1. I. Crystal structure is naturally restricted if the mineral's growth is inhibited.
  2. II. Amorphous minerals are those that have developed independently in nature.
  3. III. "Luster" and "Transparency" are synonyms for the same physical property.

    Evaluate the following statements about mineral characteristics:

    1. "Streak" and "Color" are always identical for any given mineral.
    2. "Fracture" refers to the way a mineral breaks when it does not exhibit cleavage.
    3. Specific gravity is a measure of a mineral's relative density.

      Consider the following statements regarding mineral formation:
