Commonly, a reported depression is not verified by a licensed professional geologist to be a true sinkhole, and the cause of the subsidence is not known. 9. In land surface modeling, depth to bedrock (DTB) serves as the lower boundary which affects the energy, water and carbon cycle. Basic Florida Geology Contacts between colors can be interpreted to represent positions and shapes of Holocene shorelines as sea level rose. Sinkholes form in karst terrain principally from the collapse of surface sediments into underground voids and cavities in the limestone bedrock. The mangrove islands provide protected habitat, breeding grounds, and nursery areas for many terrestrial and marine animal species.
