What Is the Atlantic Coastal Plain?
The Atlantic Coastal Plain is a U.S. physiographic region stretching along the Atlantic Ocean from New York to Florida, bounded by the Appalachian Mountains to the west and the ocean to the east.
Formation
It formed over millions of years through Appalachian erosion, sediment deposition by rivers and glaciers, and sea level changes during the last ice age.
Landscapes
Common landscapes include barrier islands, sandy beaches, salt marshes, and cypress swamps.
Natural Resources
The region produces oil, gas, coal, timber, fish, and shellfish.
Environmental Challenges
Challenges include sea level rise, coastal erosion and flooding, water pollution, and air pollution.
