A physiographic province is an area delineated according to similar terrain that has been shaped by a common geologic history.  Each province defines a region in which relief, landforms, and geology are significantly different from that of the adjoining and nearby regions. The boundary between each province is determined by a major change in topography and geology.

The provinces delineated in the map to the left were defined by Fenneman and Johnson of the U.S. Geological Survey.

Penn State University, Carnegie Mellon University, University of Rhode Island, and the Virginia Institute of Marine Science are collaborating with the U.S. EPA and private and public stakeholders of the mid- and upper-Atlantic region. Support for CARA is provided by the Global Change Research Program, Office of Research and Development, U.S. Environmental Protection Agency (Cooperative Agreement R-83053301).
