Rocks, as they are compressed, begin forming mountains above the Earth's surface when two continental plates converge. The continental crust increases in depth as the mountains grow above. The Himalayan Mountains formed at a convergent plate boundary in this manner. The rocks are smashed together causing them to __________ due to the intense heat and pressure from the colliding plates and eventually forming _____________ rock.

Responses
A melt; igneous melt; igneous
B layer; sedimentary layer; sedimentary
C recrystallize; metamorphic recrystallize; metamorphic
D melt into the Earth's interior; metamorphic

1 answer

The correct response is:

C) recrystallize; metamorphic

As the rocks are compressed and subjected to intense heat and pressure at convergent plate boundaries, they recrystallize and eventually form metamorphic rock.
