There will be a quiz at the end of this presentation.Slide6
1. Coastal PlainSlide7
The Coastal Plain runs from the fall line on the west, to the Atlantic Ocean on the east
It is a
terraced
landscapeSlide8

As sea levels rose and fell, fossils were left at various layersSlide9
Virginia Fossils
Fossils include various marine organisms like clams, scallops, sharks teeth, and other hard remainsSlide10
Virginia Fossils
Paleozoic
,
Mesozoic
, and
