A model of the rock cycle should show A. Heat and pressure as the process that changes sedimentary rock to metamorphic rock. Metamorphic rocks form when existing rocks (sedimentary, igneous, or other metamorphic rocks) are subjected to significant heat and pressure, causing physical and chemical changes.
