Answer to Question 1

Answer: Fluids, present in the original rock or introduced from magma or high-temperature dehydration and degassing reactions, create metamorphic minerals that incorporate components from the fluid molecules. Metamorphic reactions take place faster and at lower temperature in the presence of water than they do under dry conditions. The movement of fluid during metamorphism delivers some ions and removes others, so that the metamorphic rock has a different bulk composition than that of the parent rock.
