A coastal plain is an area of flat, low-lying land adjacent to a seacoast and separated from the interior by other features. One of the world's longest coastal plains is located in eastern South America. The southeastern coastal plain of North America is notable for its species diversity. The Gulf Coastal Plain of North America extends northwards from the Gulf of Mexico along the Lower Mississippi River to the Ohio River, which is a distance of about 500 miles (about 800 km). During the Cretaceous period, the central area of the United States was covered by a shallow sea, which disappeared as the land rose. Large fossilized aquatic birds called Hesperornis and Ichthyornis, found in western Kansas, indicate that the shallow sea was rife with fish.
Famous quotes containing the word plain:
“A gathering of Democrats is more sweaty, disorderly, offhand, and rowdy than a gathering of Republicans; it is also likely to be more cheerful, imaginative, tolerant of dissent, and skillful at the game of give-and-take. A gathering of Republicans is more respectable, sober, purposeful, and businesslike than a gathering of Democrats; it is also likely to be more self-righteous, pompous, cut-and-dried, and just plain boring.”
—Clinton Rossiter (1917–1970)
