Identify all of the following three statements that are reasons why retrograde metamorphism is less commonly observed than prograde metamorphism: 1) Metamorphic reactions are kinetically unfavorable at lower temperatures 2) Devolatilization (de-vo-la-tih-lih-ZAY-shun) during prior reactions removes components necessary for the formation of hydrous minerals 3) Devolatilization during prior reactions removes fluids that facilitate diffusion
