The land elevation along the coastal plain varies but generally ranges from sea level to a few hundred feet above sea level. The elevation gradually increases as you move further inland from the coast.
A coastal plain typically has a lower elevation compared to an interior plain. Coastal plains are flat, low-lying areas that lie adjacent to oceans or seas. In contrast, interior plains can have varying elevations but tend to be higher due to their distance from the coast and geological history.
The coastal plain region of the US ranges in elevation from sea level to around 200 feet above sea level. On average, the elevation of the coastal plain region is approximately 50 feet above sea level.
The highest elevation in the Gulf Coastal Plain region is about 900 feet above sea level, found in some parts of eastern Texas and western Louisiana. The majority of the Gulf Coastal Plain, however, is characterized by low-lying terrain and elevations ranging from sea level to a few hundred feet above sea level.
The Fall Line forms the border between the Piedmont and coastal plain regions in the southeastern United States. This boundary represents a shift in elevation and geology, with the Piedmont region characterized by hilly terrain and the coastal plain by flatter land closer to the coast.
The elevation of a coastal plain can vary, but typically it is at or near sea level. The coastal plain is a flat, low-lying area that extends inland from the coastline.

A plateau and a coastal plain are not defined by size, but by elevation (a plateau is at a high level) and proximity to the sea (a coastal plain is bordered on at least one side by the sea). Specific examples of each can be smaller or larger than examples of the other.
One major difference between Coastal plains and Interior plains is in elevation. Coastal plains have low elevation and low relief. Interior plains have varied elevation and low relief. Coastal plains also lie along the shore while Interior plains are surrounded by other land.
The Inner Coastal Plain is located closer to the coastline and consists of younger sediments, while the Outer Coastal Plain is further inland and consists of older, more weathered sediments. The Inner Coastal Plain tends to have more fertile soil and is generally more suitable for agriculture compared to the Outer Coastal Plain.
The coastal plain region of the US ranges in elevation from sea level to around 200 feet above sea level. On average, the elevation of the coastal plain region is approximately 50 feet above sea level.
Coastal plains are very rare on islands, as they are near the ocean. But they are plains on the borders of a country, or on an island, the shore. Interior plains are plains nowhere near the border or shoreline of the country.
