Question
Which must be true for metamorphism to occur?A.The parent rock must be in liquid form.B.The grain size must become smaller.C.The process must take place underground.D.The parent rock must be igneous.
Solution 1
For metamorphism to occur, the process must take place underground. This is because metamorphism involves the transformation of one rock type into another due to heat, pressure, or chemical processes, which typically occur beneath the Earth's surface. The parent rock does not need to be in liquid form, nor does it need to be igneous - metamorphism can occur in any rock type. The grain size does not necessarily become smaller; it can also become larger or stay the same.
Solution 2
For metamorphism to occur, the process must take place underground. This is because metamorphism involves the transformation of one rock type into another due to heat, pressure, or chemical processes, which typically occur beneath the Earth's surface. The parent rock does not need to be in liquid form, nor does it need to be igneous - metamorphism can occur in sedimentary and igneous rocks. The grain size does not necessarily become smaller; it can also become larger or stay the same.
