It is a deeply dissected plateau, with topographic relief commonly of about four hundred feet (120 meters), and frequent sandstone outcroppings and bluffs. Many coal seams are present in the area, and the Cumberland Plateau has for many years been heavily mined. At the Pottsville Escarpment, which is the transition from the Cumberland Plateau to the Bluegrass in the north and the Pennyrile in the south, there are many spectacular cliffs, gorges, rockhouses, natural bridgeRainbow Arch was formed by wind erosion A natural arch or natural bridge is a formation (or landform) where a rock arch forms, with a natural passageway through underneath. Most natural arches form as a narrow ridge, walled by cliffs, become narrower froms, and waterfallTower Fall in Yellowstone National Park A waterfall is usually a geological formation resulting from water, often in the form of a stream flowing over an erosion-resistant rock formation that forms a sudden break in elevation. Waterfalls may also be artifs. In Tennessee it borders the Highland RimThe Highland Rim is a geographic term for the area in Tennessee surrounding the Nashville Basin. Nashville is largely surrounded by higher terrain in all directions. It is located somewhat in the northwestern corner of the Basin. There are sections of the east of the Nashville BasinThe Nashville Basin is a geographic term used to describe the area surrounding Nashville, Tennessee. The term would not be correct in the geologic sense, as geologically this structure is more properly known as the Nashville Dome as the underlying rock st.
It is contiguous with the Allegheny PlateauThe Allegheny Plateau is a large, dissected plateau area in southern New York, western Pennsylvania, West Virginia, and eastern Ohio. It is divided into the unglaciated Allegheny Plateau and the glaciated Allegheny Plateau. The plateau extends southward i on the northern side, the only real difference being local naming. The sedimentary rockshale overlaid by limestone. Cumberland Plateau, Tennessee. Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main ways—by the deposition of the weathered remains of other rocks (knowns that compose both plateaus are of MississippianThis article is about the geologic period; for the North American culture, see Mississippian civilization. The Mississippian is a geologic (sub)period lasting from roughly 360 million years before the present (BP) to 325 million years BP. As with most oth and Pennsylvanian geological age, composed of near shore sediments washed westward from the original Appalachian Mountains. Some rock layers were laid down in shallow coastal waters, some, including bituminous coal seams were laid onshore in swampy environments. These are interlaced with delta formations of cross-bedded sandstones and occasionally conglomerate. There are numerous discontinuities in the beds, where they were raised high enough to be eroded, then lowered to have more sediments added on top.
Though the plateau is not composed of true mountains, and nowhere is very high, it has some of the most rugged terrain in the eastern United States, and locally is called mountains. Inhabitants of eastern Kentucky and western West Virginia mostly live in very narrow V-shaped valleys with little bottom land. Buildings and roads built along the bottom of the valley are susceptible to floods, while any structures on the steep slopes are subject to slumping. Roads are serious engineering challenges, and expensive to maintain. There are few locations available for agriculture; most people make their livelihoods from mining, timbering, or services.
