Metamorphic rocks form through a process called metamorphism, which involves changing the form or composition of existing rocks due to intense heat, pressure, or chemical activity. These conditions are typically found a few kilometers underneath the Earth's surface and can extend into the upper mantle. During metamorphism, existing minerals in the rock can recrystallize, causing the rock to undergo physical and chemical changes, resulting in the formation of new minerals and textures.
