WebMetamorphic grade is the degree to which pressure and temperature have altered parent rock. Rocks start as a protolith and progress up from low grade to high grade. Foliated … WebMetamorphic rocks are classified broadly into low, medium and high grades of metamorphic intensity, primarily due to the effects of heat on mineral stability. Heat causes atoms to vibrate; the higher the temperature, the more vibration occurs, and the weaker the bonds between atoms become.
