Questions: Which rocks show “foliation”? Sketch an example from your rock samples include labels. (Name of rock, layering, ???) Which rocks do not show “foliation”? List them by name. Which rocks show crystallization? Explain the term “contact metamorphism”. What category of Sedimentary Rock does Marble appear to be related too? Explain how you came to this conclusion. What are the three causes (agents) of metamorphism? How can you distinguish between the igneous rock granite and the metamorphic rock gneiss? See example.
