Question

What is metamorphic rocks?
​

Answer 1

Answer:

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Answer 2

Metamorphic Rocks:

• Metamorphic rocks are created through the process of metamorphism where the existing rocks (sedimentary rocks) get transformed into metamorphic rocks due to heat, or pressure.  
• They are a part of 12% of the earth’s surface or on places where two tectonic plates meet. They are also formed due to the influence of magma, which is a rich mineral fluid.
• The examples of metamorphic rocks include kyanite, garnet, sillimanite, micas, quartz etc. They can endure high temperatures.
