Will mark brainliest! 1. what are the three agents of metamorphism? 2. explain the rock cycle, by describing how an igneous rock can become a sedimentary rock, then a metamorphic rock, and then an igneous rock again.

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.

here is an image to better explain this:

Hope this helped :)
