The sediments type layers; levels close to the bottom are compacted by the load of levels higher than. Water going with the levels deposits minerals, which cement the sediments alongside one another to variety sedimentary rock. These sedimentary rock layers, if subjected to heat and tension at convergent plate boundaries, are reworked to metamorphic rock. Subducted metamorphic rocks soften as they are pushed deeper into Earth at subduction zones. The melted rock forms magma. The igneous rock fashioned from cooled magma or lava may perhaps follow a completely distinctive route from the rock cycle the next time.
