In general terms, the continental United States
is dissected by a vast central plain (the Great Plains
), while the massive Rocky Mountain system and many other mountains ranges and hills cover much of the west.
The lower Appalachian Mountains and its assorted ranges front a broad coastal plain that stretches from the far-northeast to the southern Texas coastline on the Gulf of Mexico.

They also extend along the western border of British Columbia, Canada, and the southern edge of Alaska, all the way to Kenai Peninsula and Kodiak Island
This area of the southern and southeastern U.S extends to the continental shelf and is generally characterized by level (flat) land with assorted mixed forests. The coastal areas include bayous, deltas, marshes, mud flats and swamps.
In North America the Western Continental Divide
is an imaginary line that sits atop a continuous ridge of mountain summits that divide the continent into two main drainage areas. Details and map.
The Great Plains of North America slope east from the Rockies and extend to the edge of the Canadian Shield and the western edges of the Appalachians. The land is generally smooth with large treeless areas and shallow river valleys. Minor hills and mountains are found in the Ozark Plateau of Missouri, and in the Boston Mountains and Ouachita Mountains of northwestern Arkansas and eastern Oklahoma. Sandhills and buttes cover parts of the north central U.S. in Nebraska.
