[1] [2] The four geologic regions include the Appalachian foreland, Blue Ridge, Piedmont, and Coastal Plain. These four geologic regions commonly share names with and typically overlap the four physiographic (i.e. topographic) regions of the state: the Appalachian Plateau and adjacent Valley and Ridge; the Blue Ridge; the Piedmont and the ...
The Appalachian Plateau is a province of the physiographic region of the Appalachian Highlands. The Appalachian Plateau province is divided into seven physiographic sections: Mohawk, Catskill, Southern New York, Allegheny Mountains, Kanawha, Cumberland Plateau, and the Cumberland Mountains. Each section is classified under the Appalachian ...

A physiographic province is a geographic region with a characteristic geomorphology, and often specific subsurface rock type or structural elements.The continents are subdivided into various physiographic provinces, each having a specific character, relief, and environment which contributes to its distinctiveness.
As Pangea rifted apart a new passive tectonic margin was born, and the forces that created the Appalachian, Ouachita, and Marathon Mountains were stilled. Weathering and erosion prevailed, and the mountains began to wear away. [10] By the end of the Mesozoic, the Appalachian Mountains had been eroded to an almost-flat plain. [10]
