The state of Tennessee has six principal physical regions: the Blue Ridge Mountains, the Appalachian Ridge and Valley Region, the Cumberland Plateau, the Highland Rim, the Nashville Basin, and the Gulf Coastal Plain. However, the state has three culturally and geographically identified Grand Divisions:
- East Tennessee
- Middle Tennessee
- West Tennessee
Varied ranges of the Appalachians- the Bald, Great Smoky, Holston, Stone-span eastern Tennessee. Clingmans Dome, the highest point in Tennessee, at 2,025 meters rises near the North Carolina border. It is the tallest peak on the Appalachian Trail and also is the third highest east of the Mississippi River. To the immediate west of these mountain ranges, the Appalachian Valley stretches as a series of lower ridges, rolling hills, and fertile farmlands. The flat-topped mountains of Cumberland Plateau extend to the west of the Tennessee Valley.
The Highland Rim, an elevated plain region, is located west of the Cumberland Plateau – which separates East and Middle Tennessee. The Nashville Basin region features rich farm country. Middle Tennessee is known for its high tobacco production and large American chestnut trees.
The region has relatively flat topography than East and Middle Tennessee. The portion of Gulf Coastal Plain in the state is the predominant land region by area. To the western border of Tennessee lies a wide area of rolling hills and streams that is called the Tennessee Bottoms which features mostly flood plains of the Mississippi River.
