Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.
In order to become a metamorphic rock, the rocks must undergo the rocks cycle high pressure and temperature.
Are produced when the earth tectonic plates move and collide and build up form the melting magma and sheer weight of the material can cause the rocks to undergo metamorphism.
