Metamorphic to Igneous: Melting and Cooling Metamorphic to Sedimentary: Erosion and Deposition Igneous to Metamorphic: Heat and Pressure Igneous to Sedimentary: Erosion and Deposition Sedimentary to Metamorphic: Heat and Pressure Sedimentary to Igneous: Heat and Pressure
I am so sorry if I got it wrong, sometimes I forget the rock cycle. Most likely Sedimemntary to Igneous is wrong.
