One kind of rock forms when other types of rock are changed due to extreme high temperatures is "metamorphic".
<u>Explanation:
</u>
Rock cycle stands as geology's fundamental notion. This denotes transitions occurred in three primary rock kinds as: igneous, metamorphic, and sedimentary. When extreme increased temperature and pressures are exposed on rocks then a new kind of rock is formed after chemical and physical reformation named as "metamorphic".
Basically there are two major metamorphism: regional and contact. Population of rocks are resulted from regional or dynamo thermal metamorphism. They were highly exposed to tectonic forces and related with high temperatures and pressures. Each type of rock is altered by being pulled out of its conditions of equilibrium.
