chemical reactions some amount of heat is produced. Another way of saying this is: Reactions occur because the products are a lower energy (more stable) than the reactants. Then extra energy is left over in the form of heat in the reaction. Hope this helps :)

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
