Question

5. What is Metamorphism? What are its causes?
​

Answer 1

Answer:

Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.

Answer 2

Answer:

The rocks are formed due to a complex process known as metamorphism... metamorphism involved high temperature and pressure... ... Temperature, Pressure and Chemically active fluids are the main agents causing metamorphism. Combination of changes in temperature and pressure can also cause metamorphism.
