Question

.There are many processes talked about in the lecture (and the text) that help create a metamorphic rock. Which one is the only one that is required in that process?

a.Differential stress
b.Confining pressure
c. Heat
d.Hydrothermal activity

Answer 1

b.

Step-by-step explanation:

hope it helps :)

Answer 2

b.Confining pressure

Step-by-step explanation:

• They are formed by the confining heat and pressure that they derive from the physical and chemical alteration of the igneous and the sedimentary rocks. The rocks undergo es a regional metamorphism and involve a larger body of rocks that occur over a wider area.

• Typically are associated with mountain building and orogenic events and display a distinct band of mineral and colors, which is called foliation.
• The force that drives these rocks to the various forms are those of the plate tectonics and includes the separating rides and the subducting zone along wit the continental collisions.
