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.
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.he Four Agents of Regional Metamorphism. Heat and pressure usually work together, because both rise as you go deeper in the Earth. At high temperatures and pressures, the minerals in most rocks break down and change into a different set of minerals that are stable in the new conditions.
