What is the most important factor driving metamorphism?
A)Pressure
B)Heat
C)Hydrothermal fluids
D)Orientation

Question

Quizplus · Accepted Answer

Heat is the most important factor driving metamorphism. As temperature increases, the bonds between mineral grains break and form new bonds, causing changes in the mineral composition and texture of the rock. Pressure and hydrothermal fluids can also contribute to the process, but ultimately it is the increase in temperature that drives the metamorphic transformation. Orientation refers to the alignment of mineral grains, which can be influenced by pressure but is not the primary factor driving metamorphism.
