Atlantic coastal plain

The Atlantic Coastal Plain is the flat stretch of land that borders the Atlantic Ocean (including the Gulf of Mexico). It is approximately 2200 mi long, stretching from New York, through the southeast United States and through Mexico, ending with the Yucatán Peninsula. The coastal plains have an average elevation of less than 200 meters above sea level. They extend some 50 to 100 kilometres inland from the ocean. The section from central Florida to the Yucatán Peninsula is also commonly referred to separately as the Gulf Coastal Plain.



The western border of the coastal plain is defined as the fall line, to the west of which lies the Piedmont Plateau and then the Appalachian Mountains. The eastern border is the Western Atlantic coastline with the Continental Shelf farther east.

The coastal plain is generally wet, including many rivers, marsh, and swampland. It is composed primarily of sedimentary rock and is primarily used for agriculture.
