During the formation of metamorphic rocks, what most likely causes pressure to increase? Magma pockets rise.
Gravity pulls on rocks.
Rocks melt deep beneath Earth’s surface.
Rocks beneath Earth’s surface are forced toward the mantle.

It should be D, rocks beneath Earth's surface are forced toward the mantle.

Explanation:

Metamorphic rocks form when existing rocks are exposed to extreme temperature and pressure

Rocks beneath the surface are forced toward the mantle

This movement increases pressure and heat

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
