The physiographic regions of the contiguous United States comprise 8 divisions, 25 provinces, and 85 sections. [1] The system dates to Nevin Fenneman's report Physiographic Divisions of the United States, published in 1916. [2] [3] The map was updated and republished by the Association of American Geographers in 1928. [4]
U.S. Census Bureau regions and divisions. Since 1950, the United States Census Bureau defines four statistical regions, with nine divisions. [1] [2] The Census Bureau region definition is "widely used... for data collection and analysis", [3] and is the most commonly used classification system.
Physiographic regions are a means of defining Earth's landforms into independently distinct, mutually exclusive areas, independent of political boundaries. It is based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces , and physiographic sections.
The Appalachian Highlands is one of eight government-defined physiographic divisions of the contiguous United States. [1] It links with the Appalachian Uplands in Canada to make up the Appalachian Mountains. The Highlands includes seven physiographic provinces, which is the second level in the physiographic classification system in the United ...
The landforms of Earth are generally divided into physiographic regions, consisting of physiographic provinces, which in turn consist of physiographic sections, [1] [2] [3] though some others use different terminology, such as realms, regions and subregions. [4] Some areas have further categorized their respective areas into more detailed ...
Atlantic Plain Physiographic Division of the United States. Green highlighted area is the Atlantic Plain, and the other seven physiographic divisions of the contiguous United States are shown in the legend. The Atlantic Plain is one of eight distinct physiographic divisions of the contiguous United States. Using the USGS physiographic ...
Valley and Ridge province as part of the Appalachian Highlands division, based on the U.S. Geological Survey physiographic classification. The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian Highlands division.
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 distinctiveness.
