Answer to Question 1

Mineral, chemical, and textural changes to pre-existing rocks that occur in an essentially solid state (without substantial melting). This requires increased temperature and pressure. Increasing pressure and temperature increase the grade (from low-grade through medium-grade, to high-grade).

Answer to Question 2

False
