Answer to Question 1

You just saved me a lot of time. ;)

Answer to Question 2

Answer: Many minerals are stable over limited ranges in temperature and pressure. Changes in these two variables cause reactions that result in the formation of new mineral or minerals. Laboratory experiments conducted with different minerals at measured temperatures and pressures reveal the specific conditions under which common metamorphic minerals are stable.
