UNIT . - . 6. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals.
Metamorphic Rocks. “Meta” means change (Greek). “Morph” means form (Greek). A rock that has been changed from its original form (parent rock) by heat, pressure, and fluid activity into a new form (daughter rock)..
