The protolith is subjected to heat (greater than 150 degrees Celsius) and extreme pressure causing profound physical and/or chemical change.

WebbThe rock cycle describes how the three main rock types—igneous, sedimentary, and metamorphic—change from one type to another. These changes occur through processes such as melting, solidification, and lithification. The rock cycle is driven by energy from Earth's interior and the sun. Created by Khan Academy.
