Geology. The Florida peninsula is a porous plateau of karst limestone sitting atop bedrock known as the Florida Platform. The emergent portion of the platform was created during the Eocene to Oligocene as the Gulf Trough filled with silts, clays, and sands. Flora and fauna began appearing during the Miocene.

What is Florida built upon?
The landmass that is now Florida remained shallowly submerged beneath the ocean. Coral, shellfish, and fish skeletons piled up. This created a layer of limestone hundreds (in some places thousands) of feet thick. As the Appalachian Mountains eroded, sand and clay were deposited over Floridas limestone layer.

Until geologically recently much of Florida was below a warm shallow ocean, in conditions similar to the Bahamas today, and accumulated a lot of limestone. About 23 million years ago sea level dropped enough that portions of Florida became dry land and land animals occupied the area for the first time.

TAMPA, Fla.Bunting says Tampa Bay and its surrounding areas have already swelled 9 inches. His forecast for the area in 2040 shows most coastal areas three feet underwater.
How deep is the Florida Platform?
Structure. The platform forms a rampart between the Gulf of Mexico and the Atlantic Ocean. The platform’s western edge, or Florida Escarpment, is normally defined where water depths at 300 feet (91 m) drop dramatically and in a short distance to 10,000 feet (3,000 m).
How deep is the Florida Aquifer?
The Floridan aquifer averages 1,000 feet thick, and freshwater can extend to a depth of 2,000 feet below land surface. Freshwater is thickest in the central portions of the state and rapidly thins toward the coast and the south.
What is the bedrock of Florida?
limestone
Sinkholes are common in Florida because the bedrock underlying most of the state is either limestone or dolostone, which is naturally soluble and is easily dissolved by rainwater and groundwater.
