A physiographic province is a geographic region with a characteristic geomorphology, and often specific subsurface rock type or structural elements.

The continents are subdivided into various physiographic provinces, each having a specific character, relief, and environment which contributes to its uniqueness. The physiographic provinces are then subdivided into smaller physiographic sections.


In eastern North America, the Atlantic Coastal Plain, Piedmont, Blue Ridge Mountains, Ridge-and-Valley Appalachians, and Appalachian Plateau are specific physiographic provinces.[1]

In the Western United States of western North America: the Basin and Range Province, Cascade Range, Colorado Plateau, Rio Grande rift, Great Basin, Central Valley (California), Peninsular Ranges, Los Angeles Basin, and Transverse Ranges are physiographic province examples.
