Which of the physical processes below results in the formation of metamorphic rocks? a. heat and pressure b. deposition and eruption c. weathering and erosion d. cooling and crystallization @brittanydosey

Metamorphic rocks different from igneous or sedimentary rocks in that they are not directly created in their present form.
