The Five Physiographic Provinces of Virginia
The Five Provinces
Virginia is divided into 5 provinces based on their geologic formations.
After looking at the first few slides, how many of the
provinces can you name?Do you know in which
province we live?
Be sure to take good notes!
There will be a quiz at the end of this presentation.
1. Coastal Plain
The Coastal Plain runs from the fall line on the west, to the Atlantic
Ocean on the east
• It is a terraced landscape
• 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
Virginia Fossils
• Fossils include various marine organisms like clams, scallops, sharks teeth, and other hard remains
Virginia Fossils
• Paleozoic, Mesozoic, and Cenozoic fossils are found in Virginia
2. Piedmont
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
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 )
3. Blue Ridge Mountains
Blue Ridge Facts• The billion year
old igneous and metamorphic rocks are the oldest in the state
Blue Ridge Facts
• It is a high ridge separating the piedmont from the valley and ridge province
Ready for a quick review?• 1. Which province, that has
already been described, is known for having layers of fossils?
Quick Review• 2. Which province is the largest?• 3. Which province has the oldest
rocks?• 4. Which province has slate and
kyanite mines?
Let’s see how you did!• 1. Coastal Plain• 2. Piedmont• 3. Blue Ridge• 4. Piedmont
4. Valley and Ridge Province
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
Cambrian fossil algal structures are found in the V&R Province
Limestone outcrops are common in the Valley and Ridge Province
This area is also famous for Karst
• What does karst mean?• Want some hints?
Sink holes!
Caverns!
Think you figured it out?• Karst is an irregular limestone
region with sinks, underground streams, and caverns
• The Valley and Ridge Province is famous for its caverns, can you name one?
5. Appalachian Plateau
Appalachian Plateau Facts
• The Appalachian Plateau has rugged, irregular topography and is underlain by ancient, flat-lying sedimentary rocks
Appalachian Plateau Facts
• Do you notice any thing in these layers?
COAL!
Virginia Coal
• Most of Virginia's coal is found in the Appalachian Plateau.
Virginia Coal
• These old sedimentary rocks contain many fossils and tons of coal.
• Let’s see how you do on this 10 question quiz.
• Ready? Here we go!
