1. Heat, Pressure, and Chemically active fluids
2. When the molten rock cools it forms igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks. The sedimentary particles from a sedimentary rock is formed can be originated from a metamorphic, an igneous, or sedimentary rock. All of these types of rocks can be melted to form a magma.
Hope this helps :)
1. the three agents of metamorphism includes heat, pressure, and chemically active fluids.
2. Igneous rock can become a sedimentary rock and a metamorphic rock when the magma cools and makes crystals. Metamorphic rock can become sedimentary rocks by weathering and erosion, same thing goes for igneous rock changing into a sedimentary rock. In order for a rock to become magma or igneous again is when the metamorphic rocks melts.
