  2. Objective: • Identify the 5 major regions of Virginia • Agenda: • Landscape Notes • Virginia Map • Virginia Map Analysis • Homework: • Projects due Friday • Test is Friday

  3. Landscapes • What is a landscape? • A region on Earth’s surface in which various landforms are related by a common origin. • What is a landform? • Hills, valleys, and streams

  4. Landscape Regions: • Mountains are high elevations with steep gradients. They have faulted, folded, and tilted rocks. • Plateaus are high elevations with horizontal layers. They usually have a fairly level slope • Plains are level with little change in slope. They have a low elevation with horizontal rock layers.

  5. Virginia Geology The Five Physiographic Provinces of Virginia

  6. The Five Provinces

  7. Virginia is divided into 5 provinces based on their geologic formations.

  8. 1. Coastal Plain ( Tidewater)

  9. The Coastal Plain runs from the fall line on the west, to the Atlantic Ocean on the east • It is a terraced landscape

  10. Sand, silt and clay produced by erosion of the Appalachian Mts. covers the plain • As sea levels rose and fell, fossils were left at various layers

  11. Virginia Fossils • Fossils include various marine organisms like clams, scallops, sharks teeth, and other hard remains

  12. Virginia Fossils • Paleozoic, Mesozoic, and Cenozoic fossils are found in Virginia

  13. 2. Piedmont

  14. Facts about the Va. Piedmont • It is an area of rolling hills underlain by ancient igneous and metamorphic rock • It is the largest of the provinces

  15. Mining the Piedmont • High quality slate is mined from this area • The Piedmont host one of the worlds largest kyanite mines ( see picture of kyanite )

  16. 3. Blue Ridge Mountains

  17. Blue Ridge Facts • The billion year old igneous and metamorphic rocks are the oldest in the state

  18. Blue Ridge Facts • It is a high ridge separating the piedmont from the valley and ridge province

  19. 4. Valley and Ridge Province

  20. Valley and Ridge • The Valley and Ridge Province is an area of long parallel ridges and valleys underlain by ancient folded and faulted sedimentary rocks

  21. Cambrian fossil algal structures are found in the V&R Province

  22. Limestone outcrops are common in the Valley and Ridge Province

  23. This area is also famous for Karst • What does karstmean? • Karst is an irregular limestone region with sinks, underground streams, and caverns

  24. Sink holes!

  25. Caverns!

  26. 5. Appalachian Plateau

  27. Appalachian Plateau Facts • The Appalachian Plateau has rugged, irregular topography and is underlain by ancient, flat-lying sedimentary rocks

  28. Appalachian Plateau Facts • Do you notice any thing in these layers?

  29. COAL!

  30. Virginia Coal • Most of Virginia's coal is found in the Appalachian Plateau.

  31. Virginia Coal • These old sedimentary rocks contain many fossils and tons of coal.
