An Igneous rock can change from sedimentary to metamorphic and back again or vice versa. <span>Metamorphic rocks form from heat and pressure </span>Sedimentary rocks<span> are </span>formed<span> when sediment is </span>deposited out<span> of air, ice, wind, gravity, or water flows carrying the particles in suspension.</span>
The cooling and crystallization of magma forms new igneous rock. Weathering, erosion and deposition of the material could result in the transition to sedimentary rock. Heat and pressure could then result in metamorphic rock. If this rock melts and forms magma, it could again crystallize into igneous rock.
