Florida's Geologic History

Florida has unique origins that occurred long before the Atlantic Ocean existed.  What would become the basement rocks of Florida were once part other continents.  Most of Florida's geological history occurred under the ocean, which explains why our entire state has hundreds of feet of limestone beneath it!  The sands and clays at land surface were deposited as the Appalachian Mountain belt eroded over millions of years.
