what are the names of all the keys in florida
Florida Keys
The Florida Keys have taken their present form as the result of the drastic changes in sea level associated with recent glaciations or ice ages . Beginning some 130,000 years ago the Sangamonian Stage raised sea levels to approximately 25 feet ( 7.5 m ) above the current level . All of southern Florida was covered by a shallow sea . Several parallel lines of reef formed along the edge of the submerged Florida plateau , stretching south and then west from the present Miami area to what is now the Dry Tortugas . This reef formed the Key Largo limestone that is exposed on the surface from Soldier Key ( midway between Key Biscayne and Elliott Key ) to the southeast portion of Big Pine Key and the Newfound Harbor Keys . The types of coral that formed Key Largo limestone can be identified on the exposed surface of these keys .
