Tennessee is a U.S. state located in the Southern United States. It lies adjacent to 8 other states: Kentucky and Virginia to the north; North Carolina to the east; Georgia, Alabama and Mississippi on the south; and Arkansas and Missouri on the west—which makes Tennessee tied with Missouri as the states which border the most other states. The state is trisected by the Tennessee River. The highest point in the state is the peak of Clingmans Dome at 6,643 feet, which lies on Tennessee's eastern border.
The state of Tennessee is geographically and constitutionally divided into three Grand Divisions: East Tennessee, Middle Tennessee, and West Tennessee. The Blue Ridge area lies on the eastern edge of Tennessee, on the border of North Carolina. This region of Tennessee is characterized by high mountains, including the Great Smoky Mountains, the Chilhowee Mountains, the Unicoi Range, and the Snowbird Mountains. The average elevation of the Blue Ridge area is 5,000 feet above sea level. To the west of East Tennessee lies the Cumberland Plateau. This area is covered with flat-topped mountains separated by sharp valleys. The elevation of the Cumberland Plateau ranges from 1,500 to 1,800 feet above sea level. West of the Highland Rim and Nashville Basin is the Gulf Coastal Plain, which includes the Mississippi embayment. The Gulf Coastal Plain is, in terms of area, the predominant land region in Tennessee. It is part of the large geographic land area that begins at the Gulf of Mexico and extends north into southern Illinois. Most of the state has a humid subtropical climate, with the exception of the higher mountains, which have a humid continental climate. Generally the state has hot summers and mild to cool winters with generous precipitation throughout the year.
