What is the name of the process by which rocks are changed by heat and pressure?
-
Igneous
-
Sedimentary
-
Metamorphic
-
Weathering

What is the term for a rock that has been subjected to high pressure and temperature, causing it to recrystallize?
-
Metamorphic rock
-
Igneous rock
-
Sedimentary rock
-
Extrusive rock
