The state is divided into two distinct physiographic provinces; the Alleghany Plateau on the west, comprising perhaps two-thirds of the area of the state, and forming a part of the great Appalachian Plateau Province which extends from New York to Alabama; and the Newer Appalachians or Great Valley Region on the east, being a part of the large province of the same name which extends from Canada to Central Alabama.
The physiographic features are few and very simple.
Texas is crossed by four physiographic provinces.
North Dakota lies in the Prairie Plains and Great Plains physiographic provinces.
