Presentation Transcript

  1. Geologic Provinces of Virginia

  2. A. Appalachian Plateau • Southwestern part of VA • Rugged, irregular topography • Rich in coal and natural gas

  3. B. Valley and Ridge • This is where we live • Underlain by ancient folded and faulted sedimentary rocks • Many caves and sinkholes • Limestone is the common rock type • Karst Topography

  4. C. Blue Ridge • The oldest rocks in VA • Billion-year-old igneous and metamorphic rocks • The highest area of VA

  5. D. Piedmont • The largest province in VA • Rolling hills • Ancient igneous and metamorphic rock • The FALL ZONE is the elevation change between the Piedmont and the Coastal Plain

  6. E. Coastal Plain • Flat • Unconsolidated sediment produced by erosion of Appalachian Mountains • The youngest rocks in VA • Richmond is on the border of the Piedmont and the Coastal Plain
