METAMORPHIC ROCKS FORMATION
The
temperatures and pressures inside the Earth are much
higher than those on the Earth's surface. When rocks
are subjected to greater heat and pressure inside the
Earth, they are changed into rocks which are
different from the original. This change occurs while
the origianl rocks are still in a solid state. The
new rocks that are gormed by changing existing rocks
under heat and pressure are caleed metamorphic rocks.
