Answer to Question 1

Answer: Temperature increases along the geothermal gradient as rocks are buried deeper in Earth's crust by tectonic processes or by the weight of the rocks above them. Rocks also experience higher temperatures near igneous intrusions. A temperature increase can drive the chemical reactions of metamorphism. These reactions include dehydration and degassing of minerals that contain water or gas molecules in their structure. Minerals are stable within a defined range of temperature and pressure. Outside of this stability range, original minerals break down and form new minerals.
