Standard 8 Freshwater Resources

Created when thick sedimentary deposits were extensively folded and faulted, this province today is characterized by long, narrow, parallel ridges of sandstone rising above valleys of limestone. These valleys have numerous examples of Karst topography, such as the Luray Caverns. Which Virginia province is being described above?

• Valley and Ridge province

• Blue Ridge province

• Piedmont province

• Coastal Plain province
