The Process of Changing a Rock by Extreme Heat .

The rock cycle is the series of transformative processes rocks experience, and the different forms they take. Metamorphism is only one process in this cycle, but it's foundational in that it prepares sedimentary rocks to be melted back down into magma, after which that magma can re-cool to form new igneous rock. In this context, metamorphism can be viewed as a process that concentrates the ...
