Question

what is metamorphism? what are its causes?

Answer 1

Hi friend...

The rocks are formed due to a complex process known as metamorphism... metamorphism involved high temperature and pressure... due to these process the physical and chemical properties of the rocks are completely changed and forms in to a new type of rocks knwn as metamorphism...


causes.... of metamorphism...

Temperature, Pressure and Chemically active fluids are the main agents causing metamorphism. Combination of changes in temperature and pressure can also cause metamorphism. For example, certain metamorphic rocks are found under certain conditions of pressure and temperature...

hope it helps you..

Answer 2

It is the change of minerals and geological texture.The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. there are three types of metamorphism exists
1)contact
2)dyanamic
3) regional
geometric ingredients in the earth caused by radioactive decay are the most common cause of temperature differences and thus a cause of metamorphism
heat and pressure are also the direct cause of metamorphism
also hydrothermal fluids play an important role causing metamorphism. .
