The Atlantic Seaboard Fall Line, or Fall Zone, is a 900-mile (1,400 km) escarpment where the Piedmont and Atlantic coastal plain meet in the eastern United States. [2] Much of the Atlantic Seaboard fall line passes through areas where no evidence of faulting is present.

The Piedmont Province is a physiographic province of the larger Appalachian Highlands physiographic division and consists of the Piedmont Upland, and the Piedmont Lowlands sections. [ 2 ] The Atlantic Seaboard Fall Line marks the Piedmont's eastern boundary with the Coastal Plain.
The Coastal Plain is the largest geographic area of the state, and covers roughly 45% of North Carolina. The Coastal Plain begins along the fall line, a line that marks the boundary between metamorphic/igneous rocks of the Piedmont province (to the west) and sedimentary rocks of the Coastal Plain province (to the east). Rapids are common where ...
The Coastal Plain refers the region to the east and south of the Fall Line, and is characterized by sedimentary rocks of Cretaceous and Cenozoic age, as well as younger sediments. The Coastal Plain is a relatively flat and fertile area of land. The Coastal Plain extends from the Fall Line to the Atlantic Ocean. Today the Coastal Plain is home ...
The Fall Line is the surface expression of the Coastal Plain unconformity, an erosional surface that separates younger, overlying rocks of the Coastal Plain from older igneous and metamorphic rocks of the Appalachian Piedmont beneath the unconformity.
The coastal plain in Delaware is by far the largest province, encompassing all of the state south of the Kirkwood Highway from Newark to Wilmington. [1] The unconsolidated sediments of the coastal plain range in age from Cretaceous to recent. They consist of gravels, sands, silt, and clay, with varying mixtures of all four.
The organization leads a series of guided hikes along proposed sections of the Fall Line, each October. The trail's name refers to its location along the Atlantic Seaboard's geological Fall Line, the 900 mi (1,400 km)-long escarpment where the Piedmont and Atlantic Coastal Plain meet. [7]
