Consider the following questions:
Use the rock cycle as a starting point for a discussion of the conditions responsible for the diver rocks that we find on Earth.
What are the chef rock types, and which processes may change one rock type into another?
What are the temperature and pressure conditions leading to differing characteristics of rocks?
Describe how rocks and processes may vary with respect to plate tectonic settings.
How do the minerals common in rocks and sediments reflect or respond to the changing conditions?
How might the apparent rock ages determined by radioactive dating methods be established or altered in the various environments?
