Question

Metamorphic rocks that foliate are created by

unequal pressure
equal pressure

Answer 1

Metamorphic rocks that exhibit foliation are typically formed by **unequal pressure**. Foliation occurs when rocks are subjected to differential stress, which causes the minerals within the rock to align along planes in response to that stress. This alignment results in a layered or banded appearance. In contrast, if the pressure is equal in all directions, the rock tends to develop a more massive texture without foliation.
