Summary: The rock cycle consists of many parts and the main rocks are sedimentary, metamorphic and igneous rocks. If you start with magma you can crystallize it in the ground above or below, above makes extrusive igneous and below makes instructive igneous rock. If you then go to to instructive igneous you can melt it into magma, expose and weather it to soil and increase temperature and pressure into metamorphic rock. If instead you went to extrusive you could weather it into soil or increase temp. and pressure and make it into metamorphic rock. If you went to soil you could erode it into sediments.
