The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.
Even with their new mineral assemblages, metamorphic rocks may have the same overall chemistry they had before metamorphism. Fluids are an important agent of metamorphism. Most rocks contain some water, but sedimentary rocks hold the most. First there is the water that was trapped in the sediment as it became rock.Second is the water that is liberated by clay minerals as they change back to feldspar and mica.y Andrew Alden. Metamorphic rocks are the third great class of rocks. These are what happens when sedimentary and igneous rocks become changed, or metamorphosed (changed in form), by conditions underground. The four main agents that metamorphose rocks are heat, pressure, fluids and strain.
