Answer:

Option B and Option D

Explanation:

  • Plate movement responsible for the exposure of the metamorphic rock to the surface of the earth: The collision of the tectonic plate of the earth produces tremendous pressure and heat which initiates the process of regional metamorphism. Due to which huge portions of rock are exposed to such pressure which ends up in the formation of metamorphic rock above the earth's surface. Many mountain ranges with active plate movements are, therefore, metamorphic rocks.
  • Wind and water erosion responsible for pushing metamorphic rock on the earth surface: One of the main reasons for the exposure of metamorphic rock above the surface of the earth is due to weathering and erosion. The top layer of the earth's crust is severely harmed and exposed due to continuous erosion as water takes away loosely bound sand and soil whereas wind sweeps up the sand in desert areas resulting in exposure of rocks on the surface.
