Answer:
Rocks beneath the surface are forced toward the mantle
Magma pockets rise, increasing heat.
Temperature and pressure cause to change minerals
Explanation:
Metamorphic rocks are those that originate from the transformation of an existing rock, called a protolite. In the formation of the metamorphic rock it is necessary that the protolite undergoes several processes of chemical and physical chemical nature, called metamorphism, which causes a change in the structure and minerals of the protolite, forming a new rock, the metabolic rock.
In summary, we can say that during the metamorphism rocks beneath the surface are forced toward the mantle. This increases pressure and heat. Magma pockets rise, increasing heat. Temperature and pressure cause to change minerals
