What type of elevation does Allegheny Front and Appalachian Platea have in common?
Allegheny Front The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, and eastern West Virginia, USA. The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau (locally called the Allegheny Plateau) to its west. The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.
Appalachian Ohio Appalachian Ohio is a bioregion and political unit in the southeastern part of the U.S. state of Ohio, characterized by the western foothills of the Appalachian Mountains and Appalachian Plateau. The Appalachian Regional Commission defines the region as consisting of thirty-two counties. This region roughly overlaps with the Appalachian mixed-mesophytic forests, which begin in southeast Ohio and southwest Pennsylvania and continue to north Georgia and Alabama. The mixed-mesophytic forest is found only in Central and Southern Appalachia and eastern/central China. It is one of the most biodiverse temperate forests in the world.
