Which graph best represents the textures of granite, pegmatite, and rhyolite?

• A

• B

• C

• D

Which property is most useful in distinguishing pyroxene from amphibole?

• sample size

The diagrams below show the crystal shapes of two minerals. Quartz and halite have different crystal shapes primarily because

• light reflects from crystal surfaces

• of the internal arrangement of the atoms

• of impurities that produce surface variations

• energy is released during crystallization
