HEEEPPP What is the process of an igneous to a metamorphic rock

If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten. When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.

Metamorphic rocks: form by recrystallization of either igneous or sedimentary rocks. This happens when the temperature, pressure or fluid environment change and a rock changes its form (e.g. limestone turns to marble). The range of temperatures for metamophism is 150C up to the melting temperature.
