Canals, ditches, dams, and levees were built to drain swamps for agriculture, oil and gas exploration, and urban development. Flooding direction is confirmed by radioisotope dates on Holocene corals. Normally, soil is referred to as the skin of the earth. According to the Florida soil survey, the sand is not as deep as you might think. These include subsurface expansive clay or organic layers that compress as water is removed; decomposing stumps or organic debris; collapsed or broken sewer and drain pipes or broken septic tanks;improperly compacted soil after excavation work; or decomposing or compressedburied trash and other debris. A type of limestone made up almost entirely of cemented shell fragments. [7] Because Florida is not located near any tectonic plate boundaries, earthquakes are very rare, but not totally unknown. The most extensive areas of pale colors (i.e., shallowest depths mapped) are around the Marquesas Keys and along the inner shelf of the middle and upper Keys.
