Question

How do temperature and pressure affect metamorphism?

A. Pressure and temperature increase as you go up to the crust.
B. The deeper the rock depth, the higher the pressure and temperature.
C. Foliation happens as there is an increase in the pressure and
temperature.
D. Magma cannot bake the surrounding rocks due to the difference in
temperature​

Answer 1

(B)."The deeper the rock depth, the higher the pressure and temperature", affect of metamorphism.

Explanation:

• Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
• With depth, heat and pressure and temperature. This pressure can actually push the mineral gaps out of the rock. The rocks become denser as a result of this. The combination of heat and pressure causes the rock to flow rather than break or fracture.
