Answer:
True
Explanation:
Metamorphic rocks are changed rocks. These are rock types that have been subjected to intense pressure and temperature to have effected mineralogical changes in a pre-existing.
During mountain building processes usually at plate margins, rocks are subjected to a very high level of tectonic stress and elevated temperature resulting from frictional heating between rocks.
Stress is the force applied per unit area. In a rock body, it causes deformation. The evidence of the deformation is recorded as fabrics in metamorphic rocks. An ideal environment for shearing stress and deformation to take place is where orogenic forces(mountain building) are at work.
