Answer:
The type of metamorphism that takes place in response to large-scale mountain- building process is called as "Regional Metamorphism".
Step-by-step explanation:
Regional Metamorphism:
- It is caused by massive geologic means such as mountain-building.
- These rocks, when exhibited to the surface, show the incredible pressure that induces the rocks to be bent and divided by the mountain building process.
- Regional metamorphism normally produces foliated rocks such as slates, gneiss, and schist.
- The differential strain normally occurs from tectonic forces that generate compressional tensions in the rocks, such as when two continental bodies collide.
- Hence, regionally metamorphosed rocks occur in the cores of thrust mountain regions or eroded mountain ranges.
