Here's a breakdown:

* Limestone: This rock forms from the accumulation of marine organisms' shells and skeletons over millions of years. It's very porous and permeable, which contributes to Florida's abundant groundwater resources.

* Other sedimentary rocks: While limestone is the dominant rock type, there are also some deposits of sand, clay, and other sedimentary materials found in Florida.

It's important to note that the rock formations of Florida are relatively young compared to those in other parts of the world. The peninsula's geology is largely shaped by the ongoing geological processes of deposition, erosion, and sea level changes.
