Question: what are the names of all the keys in florida

title: Florida Keys
text: 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 .
