1.Heat and/or pressure 2. Weathering and erosion 3.melting. The heat and pressure will make the sedimentary rock into a metamorphic rock. The melting will make it into magma which will then cool and become igneous rock. The weathering and erosion will make the rock break down into small parts (sediments) which will stay like that for a long time and eventually become a sedimentary rock once again.
