The Five Physiographic Provinces of Virginia
50Slide2
The Five Provinces
50Slide3
Virginia is divided into 5 provinces based on their geologic formations.Slide4
After looking at the first few slides, how many of the provinces can you name?
Do you know in which province we live?Slide5Slide6
Coastal PlainSlide7
Coastal Plain
Chesapeake Bay:Slide8
Coastal Plain
A flat area underlain by young unconsolidated sediments such as sand
, silt, and clay. Slide9
Coastal Plain
These layers of sediment were produced by erosion of
the Appalachian Mountains and then deposited on the Coastal Plain.Slide10
Coastal Plain
Known for fossils
Fossils
include various marine organisms like clams, scallops, sharks teeth, and other hard remainsSlide11
PiedmontSlide12
PiedmontSlide13
Piedmont
An area of rolling hills
underlain by mostly ancient igneous and metamorphic rocks. Slide14
Piedmont
The igneous rocks are the roots of ancient volcanoes formed prior to the formation of the Appalachian Mountains.
This
is the
largest
province and the province we live in. Slide15
Piedmont
Important rock and minerals include pegmatites, slate,
kyanite
, gold, and pyrite.
Known for rock and mineral minesSlide16Slide17
Blue RidgeSlide18
Blue Ridge
A high ridge separating
the Piedmont from the Valley & Ridge Provinces. Slide19
Blue Ridge
The billion year old igneous and metamorphic rocks are the oldest in the stateSlide20
Blue Ridge
Metamorphism of these rocks occurred during the formation of the Appalachian Mountains.Slide21
Let’
s Review!Which province, that has already been described, is known for having layers of fossils?
Which province is the largest?
Which province has the oldest rocks?
Which province has slate and
kyanite mines?Slide22Slide23
Valley & RidgeSlide24
Valley & RidgeSlide25
Valley & Ridge
An area with long parallel ridges & valleys underlain by ancient folded & faulted sedimentary rocks which occurred during a collision between Africa & North America – this Paleozoic era collision produced the Appalachian Mountains. Slide26
Valley & Ridge
Known for karst landforms such as caves
and
sinkholes
formed from limestone
. Slide27Slide28
Appalachian PlateauSlide29
Appalachian Plateau
The Appalachian Plateau has rugged, irregular topography and is underlain by ancient, flat-lying sedimentary rocks
This area is actually a series of plateaus separated by
faults
.Slide30
Appalachian Plateau
Do you notice any thing in these layers?Slide31
Appalachian Plateau
This area is known for the sedimentary rock coalSlide32
Let’s ReviewSlide33
Let’s Review
Which province is covered by sand, silt and clay?
This
province contains billion year old
rocks?
Which province is underlain by ancient, flat-lying sedimentary rocks?Slide34
Let’s Review
This province has rolling hills underlain by ancient rocks.
What do we call an irregular limestone region with sink holes and caverns?Slide35
Let’s Review
Which province is at the most western part of the state?
Which province is the largest?
Which province is famous for coal?
