Answer 6

The metamorphic rocks are a denser version of igneous and sedimentary rocks.
When an igneous or sedimentary rock is subjected to extreme heat and pressure for a prolonged period, the composition of the existing rocks changes to become more concentrated, which eventually results into the formation of metamorphic rocks.
Metamorphic rocks are usually formed in the lithosphere and the asthenosphere, two uppermost layers of the Earth's crust.
