What is metamorphism and what kind of changes occur to a rock during metamorphism? What
conditions produce metamorphism? Are these changes linked or independent? Can you explain
your answer? What does it mean to be high or low grade?

What is devolitilization and how and when does it occur in minerals?

Metamorphism occurs over a broad pressure and temperature range. How can we determine the
pressure and temperature at which a rock metamorphosed? Where/How are rocks
metamorphosed by high temperatures and low pressures? by high pressures and low
temperatures? by high pressures and temperatures?

What is contact metamorphism and how can it be distinguished from regional metamorphism?
