Which statement describes uniformitarianism? the continents at one time were all part of a large landmass, but then they separated and moved apart. in an undisturbed layer of rock, older rocks lie at the bottom and younger rocks lie at the top. the forces that act to change earth's surface today are the same forces that acted upon earth's surface in the past. layers of sedimentary rock contain more fossils than layers of metamorphic or igneous rock.

During metamorphic processes, increased pressure and temperature can affect the of minerals in rock. rocks subjected to very high pressure are typically than others because mineral grains are squeezed together, and the atoms are more closely packed. during metamorphic processes, water facilitates the transfer of ions between and within minerals, which can the rate at which metamorphic reactions take place. the growth of new minerals within a rock during metamorphism has been estimated to be about per million years. metamorphism is commonly associated with convergent plate boundaries, where two plates move toward each other. during contact metamorphism, a large intrusion will contain thermal energy and will cool much more slowly than a small one. metamorphosed sandstone is known as the metamorphic rock made from metamorphosed shale, was once used to make blackboards for classrooms
