1 The Five Physiographic Provinces of Virginia

2 The Five Provinces

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

4 After looking at the first few slides, how many of the provinces can you name? Do you know in which province we live?

5 Be sure to take good notes! There will be a quiz at the end of this presentation.

6 1.Coastal Plain

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

8 As sea levels rose and fell, fossils were left at various layers

9 Sand, silt and clay produced by erosion of the Appalachian Mts. covers the plain

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

11 Virginia Fossils Paleozoic, Mesozoic, and Cenozoic fossils are found in Virginia

12 2. Piedmont

13 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

14 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 )

15 3. The Blue Ridge

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

17 Blue Ridge Facts It is a high ridge separating the piedmont from the valley and ridge province

18 Ready for a quick review? 1. Which province, that has already been described, is known for having layers of fossils?

19 Quick Review Quick Review 2. Which province is the largest? 3. Which province has the oldest rocks? 4. Which province has slate and kyanite mines?

20 Let’s see how you did! 1. Coastal Plain 2. Piedmont 3. Blue Ridge 4. Piedmont

21 4. Valley and Ridge Province

22 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

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

24 Limestone outcrops are common in the Valley and Ridge Province

25 This area is also famous for Karst. What does karst mean? Want some hints?

26 Sink holes!

27 Caverns!

28 Think you figured it out? Karst is an irregular limestone region with sink holes, underground streams, and caverns The Valley and Ridge Province is famous for its caverns, can you name one?

29 5. Appalachian Plateau

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

31 Appalachian Plateau Facts Do you notice any thing in these layers?

32 COAL!

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

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

35 Let’s see how you do on this 10 question quiz. You may use your notes Ready? Here we go!
