Extended data
The topography of the United States is varied, with high terrain in the west and low terrain in the east. There are coastal plains on the east coast, which are wide in the south and narrow in the north, extending to New Jersey and Long Island, and there are also some glacial sedimentary plains. Behind the coastal plain is a hilly area with undulating terrain, extending all the way to the Appalachian Mountains in North Carolina and New Hampshire, with an altitude of 1, 830 meters.
To the west of the Appalachian Mountains is the central plain of the United States, with relatively flat terrain. The Great Lakes and the Mississippi-Missouri River Basin are the earliest in the world.
Four major rivers are also located here. To the west of the Mississippi River, the topography of the internal plain began to rise, and finally it entered the great plain with a vast area and few topographical features in the central United States.
