in a rock.
* Describe the plate tectonic settings in which metamorphic rocks form.
* Explain what foliation
is, tell what causes it, and give examples of three foliated
metamorphic rocks.
* Describe and give the names of three non-foliated metamorphic rocks.
* Sketch a diagram illustrating how rocks of each of the three major
