Ancient Convergent Plate Boundary-Appalachian Mountain Range. The range is mostly located in the United States but extends into southeastern Canada, forming a zone from 100 to 300 mi (160 to 480 km) wide, running from the island of Newfoundland 1,500 mi (2,400 km) southwestward to Central Alabama in the United States.
The Appalachian Mountains include from west to east: the Appalachian Plateau, Valley and Ridge, the Blue Ridge Province, and the Piedmont Region. The Blue Ridge Province is bounded on the west by the Great Smokies Fault near the Tennessee boundary and on the east by the Brevard Fault Zone. The mountains grew out of stacking and shuffling of thin horizontal sheets in several orogenies. The thrusting, shuffling rock sheets mixed the rocks like a deck of cards.
