What is the most likely place a metamorphic rock might form?

Metamorphic rocks are formed on the earth's core

Explanation:

    Metamorphic rock is a type of rock derived from the metamorphosis (transformation) of magmatic or sedimentary rocks that undergo modification in their atomic composition, due to the influence of different environmental conditions in which they are inserted compared to the places where they were originally formed.

      In most cases metamorphic rocks form from other rocks, which are subjected to intense pressures or high temperatures. This process occurs naturally due to the intense and constant movement of the earth's core, causing the periodic movement of the planet's crust (the covering of earth and rocks that make up the outer region of the planet). The movement of the crust, in turn, initiates a rearrangement in the rocks located in the upper part, being that when the magmatic and sedimentary rocks are pushed to lower levels, thus giving rise to the process of formation of the metamorphic rock.

i am a little confused myself with what goes with the letters and what goes with the numbers but ill do my best to you

the cordillera states and grand canyon are along the southwest u.s. and northern mexican pacific.

the great plains and southwest desert are also the prairie and home to many earthquakes too .
