{{Main|United States}}
The [[Contiguous United States|lower 48 U.S. states]] can be divided into roughly five [[physiographic]] provinces:
# The [[American Cordillera|American cordillera]]
# The [[Canadian Shield]]<ref name="Marianopolis"/> Northern portion of the upper [[Midwestern United States|midwestern U.S.]]
# The stable platform
# The [[coastal plain]]
# The Appalachian [[orogeny|orogenic]] belt

The geology of [[Alaska]] is typical of that of the cordillera, while the major islands of [[Hawaii]] consist of [[Neogene]] [[volcano|volcanics]] erupted over a [[hotspot (geology)|hot spot]].
