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.
Social and economic stratification in Appalachia The Appalachian region of the Eastern United States is home to over 25 million people and covers parts of mostly mountainous areas of 13 states, including Mississippi, Alabama, Pennsylvania, New York, Georgia, South Carolina, North Carolina, Tennessee, Virginia, Kentucky, Ohio, Maryland, and the entire state of West Virginia. The near-isolation of the area's rugged topography is home to communities with a distinct culture, who in many cases are put at a disadvantage because of the transportation and infrastructure problems that have developed.
