5 provinces of Virginia
Transcript of 5 provinces of Virginia
Sedimentary rock and sediment
Includes VA Beach oceanfront
Fossils=Seashells & Ocean critters
Area is rich in sand and gravel resources
Major cities=Norfolk, Virginia Beach
A gently sloping area with rolling hills.
Pied=foot; mont=mountains (sits at the foot of the mountains)
Located in central VA
Part of the Appalachian Mountains
Valley & Ridge
An area of long, parallel ridges separated by valleys.
Sections of hard, resistant rocks make up the ridges, while soft, eroded limestone makes up the valleys.
Created when the North American plate collided with the African plate (Africa and Europe) 265-300 million years ago!
Major city=Alleghany County
Feature=The "Great" vally (massive valley which is home to Blacksburg, VA (VA Tech located in this city.)
A series of plateaus separated by wide valleys.
Area is called "the boot" because it resembles a boot.
Located in the Southwest portion of the state.
The blue ridge province is characterized by a narrow mountain range which lie north of Roanoke, VA. This is a older and more rugged line of mountains than the Rocky Mountains.
