6. Which of the following best describes the conditions of contact metamorphism?

a. Pressure is very high, and the rock is deeply buried, and the temperatures are raised by the earth's internal heat.
b. Pressure is fairly low, and the rock is in the upper crust and heat is supplied by a nearby magma body.
c. Generally associated with the convergence of two lithospheric plates.
d. Generally associated with the divergence of two lithospheric plates.
e. Occurs as a result of numerous layers of sedimentary rock piled atop one another.

Final answer:

Contact metamorphism occurs due to high temperature and low pressure when magma intrudes pre-existing rock, leading to different metamorphic facies based on pressure conditions.


Explanation:

Contact metamorphism occurs in rock exposed to high temperature and low pressure when hot magma intrudes or lava flows over pre-existing rock. This process produces various metamorphic facies such as hornfels, greenschist, amphibolite, or granulite facies based on pressure conditions. Contact metamorphism is associated with the heat from magma chambers and occurs at shallower depths, resulting in fine-grained rocks lacking foliation.
