Tennessee, officially the State of Tennessee, is a landlocked state in the Southeastern region of the United States. It borders Kentucky to the north, Virginia to the northeast, North Carolina to the east, Georgia, Alabama, and Mississippi to the south, Arkansas to the southwest, and Missouri to the northwest. Tennessee is the 36th-largest by area and the 15th-most populous of the 50 states. According to the United States Census Bureau, the state's estimated population as of 2024 is 7.22 million.
In geology and related fields, a stratum is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either bedding surfaces or bedding planes. Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both bed and lamina. Related terms are substrate and substratum (pl.substrata), a stratum underlying another stratum.
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia. The terms "Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains. The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two. Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky.
The Tennessee Valley is the drainage basin of the Tennessee River and is largely within the U.S. state of Tennessee. It stretches from southwest Kentucky to north Alabama and from northeast Mississippi to the mountains of Virginia and North Carolina. The border of the valley is known as the Tennessee Valley Divide. The Tennessee Valley contributes greatly to the formation of Tennessee's three legally recognized sectors.

There were three formations known as the Army of Mississippi in the Confederate States Army during the American Civil War. This name is contrasted against Army of the Mississippi, which was a Union Army named for the Mississippi River, not the state of Mississippi.
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality.
The Chickasaw Bluff is the high ground rising about 50 to 200 feet (20–60 m) above the Mississippi River flood plain between Fulton in Lauderdale County, Tennessee and Memphis in Shelby County, Tennessee.
The Coon Creek Formation or Coon Creek Tongue is a geologic unit and Konservat-Lagerstätte located in western Tennessee and extreme northeast Mississippi. It is a sedimentary sandy marl deposit, Late Cretaceous (Maastrichtian) in age, about 70 million years old. The formation is renowned for its pristine fossils of Late Cretaceous marine invertebrates, including gastropods, bivalves, decapod crustaceans, and ammonites, particularly at Coon Creek in McNairy County, Tennessee, which the formation is named for. It is also known for producing fosslis of marine vertebrates, such as mosasaurs and plesiosaurs. Notable fossils from this formation is the gastropod Turritella, the bivalve Pterotrigonia thoracica, as well as other fossils such as crabs.
The geology of Tennessee is as diverse as its landscapes. Politically, Tennessee is broken up into three Grand Divisions: East, Middle, and West Tennessee. Physically, Tennessee is also separated into three main types of landforms: river valley plain, highlands and basins, and mountains.
The Southern Intercollegiate Athletic Association (SIAA) was one of the first collegiate athletic conferences in the United States. Twenty-seven of the current Division I FBS football programs were members of this conference at some point, as were at least 19 other schools. Every member of the current Southeastern Conference except Arkansas, Missouri and Oklahoma, as well as six of the 15 current members of the Atlantic Coast Conference formerly held membership in the SIAA.
Dana Xenophon Bible was an American football player, coach of football, basketball, and baseball, and college athletics administrator. He served as the head football coach at Mississippi College (1913–1915), Louisiana State University (1916), Texas A&M University, the University of Nebraska (1929–1936), and the University of Texas (1937–1946), compiling a career college football record of 198–72–23. Bible was also the head basketball coach at Texas A&M from 1920 to 1927 and the head baseball coach there from 1920 to 1921. In addition, he was the athletic director at Nebraska from 1932 to 1936 and at Texas from 1937 to 1956. Bible was inducted into the College Football Hall of Fame as a coach in 1951.
The Window Cliffs State Natural Area covers 275 acres (111 ha) in Putnam County, Tennessee, near Cookeville. The Window Cliffs is the name of a prominent group of natural bridges in a narrow 200-foot-tall (61 m) ridge in the neck of a meander of Cane Creek. The day-use area is only accessible by hiking a 2.7 miles (4.3 km) trail. The Window Cliffs was an acclaimed destination in the nineteenth and early twentieth centuries. The area contains several state-listed endangered plants.
The Brassfield Formation, named by A.F. Foerste in 1906, is a limestone and dolomite formation exposed in Arkansas, Ohio, Kentucky, Indiana, Tennessee and West Virginia in the United States. It is Early Silurian in age and well known for its abundant echinoderms, corals and stromatoporoids. In Ohio, where the unit has escaped dolomitization, the Brassfield is an encrinite biosparite with numerous crinoid species.
