Which of the following is TRUE about contact metamorphism?

Which of the following transformations is directly related to pressure in producing metamorphic rocks?

Which of the following metamorphic rocks would NOT come from mud rock? 

What process contributes to the metamorphism of oceanic crust at the zone of spreading ridge?

Rigel argued with his classmates that the rock that he found in the campsite near the foot of the Taal volcano was a metamorphic rock. Others claimed that it was a volcanic rock because it was found near a volcano hence, an igneous rock. What features of the rock would have convinced Rigel that it was a metamorphic rock and not an igneous rock?

In which geographic area will there be a metamorphic rock with very distinct foliations?

Low-grade metamorphism takes place at temperatures between 200 ^oC to 320 ^oC, and at relatively low pressure. Which metamorphic rock is created in this environmental setting?

How does the presence of a hot pluton contribute to metasomatism?

I.    The heat coming from the pluton heats up the rock and triggers the recrystallization of its original minerals.

II.  A hot pluton heats the surrounding water, causing ground water to circulate around the rocks.

III.  Magma within the pluton cooks up the minerals and destroys its original crystal arrangements.

How does metasomatism occur?

Which of the following statements about the metamorphism of shale is FALSE?
