How do metamorphic rocks work?

Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

Explanation:

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
