Q. Which must be true for metamorphism to occur?
✅ Correct Answer: (D)
All the above
Explanation: Metamorphism is the change of minerals or geologic texture in pre-existing rocks, without the protolith melting into liquid magma. The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids.
The parent rock must be in solid form. Tons of pressure must be applied for metamorphism to happen. The process must take place underground.
