The U.S. state of Georgia is commonly divided into four geologic regions that influence the location of the state's four traditional physiographic regions. [ 1 ] [ 2 ] The four geologic regions include the Appalachian foreland, Blue Ridge, Piedmont, and Coastal Plain.
Georgia is a state in the Southeastern United States in North America.The Golden Isles of Georgia lie off the coast of the state. The main geographical features include mountains such as the Ridge-and-valley Appalachians in the northwest, the Blue Ridge Mountains in the northeast, the Piedmont plateau in the central portion of the state and Coastal Plain in the south.
USGS map of Georgia elevations. Georgia consists of five principal physiographic regions: The Cumberland Plateau, Ridge-and-Valley Appalachians, Blue Ridge Mountains, Piedmont, and the Atlantic coastal plain. [28] Each region has its own distinctive characteristics.
The first statewide geologic map of Georgia was published in 1825. It was a 1:1,000,000 scale map of Georgia and Alabama published by Henry Schenck Tanner. [3] In 1849 W.T. Williams published the geological features for the state on a 1:120,000 scale map within George White's (1849) Statistics of the State of Georgia report. [4]
The physiographic regions of the contiguous United States comprise 8 divisions, 25 provinces, and 85 sections. [1] The system dates to Nevin Fenneman's report Physiographic Divisions of the United States, published in 1916. [2] [3] The map was updated and republished by the Association of American Geographers in 1928. [4]
The Cumberland Plateau is a deeply dissected plateau, with topographic relief commonly of about 400 feet (120 metres), and frequent sandstone outcroppings and bluffs.. At Kentucky's 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 bridges, and ...

The landforms of Earth are generally divided into physiographic regions, consisting of physiographic provinces, which in turn consist of physiographic sections, [1] [2] [3] though some others use different terminology, such as realms, regions and subregions. [4] Some areas have further categorized their respective areas into more detailed ...
