16. How does metasomatism process occur?
A. Recrystallization of minerals through contact metamorphism due to heat.
B. The dissolve minerals in the fluids react with rocks that the fluids penetrate causing changes in chemical and mineral compositions.
C. Destruction of arrangement of original minerals by impact due to asteroid bombardment.
D. Recrystallization and alignment of minerals through regional metamorphism due to heat and pressure.

17. In which geographic area will there be a highest potential for regional metamorphism?
A. Mid-ocean ridge in the Atlantic Ocean
B. In the Philippine trench
C. Near an igneous intrusion
D. At the core of the Himalayas

18. In which geographic area will there be a metamorphic rock with very distinct foliations? A. near magma intrusion
B. at the core of the Himalayas
C. in the mid-ocean ridge in the Atlantic Ocean D. in convergent boundaries where plates move towards each other

19. How does the presence of a hot pluton contribute to metasomatism?
I. The heat coming from pluton heats up the rock and triggers recrystallization of its original minerals
II. A hot pluton heats the surrounding water, causing groundwater to circulate around the rocks.
III. Magma within the pluton cooks up the minerals and destroy its original crystal arrangements.
A. Only I is correct
B. Only II is correct
C. I and II are correct
D. All are correct
