Sinkholes

====[|Sinkholes] (A.K.A sinks, shake holes, swallow holes, swallets, dolines) are depressions caused by the erosions of limestone underneath the surface. Groundwater and other chemicals can erode the limestone and make funnel-shaped ==== depressions. Dry and high locations are more prone to have these sinkholes. The mud/soil at the top of the limestone (ground) cave in when the limestone support collapse. Sinkholes are different from potholes. If the water is blocked, the water drained into the sinkhole could form a lake. Sometimes even cave roofs collapse to form sinkholes as large as 200m in diameter.

Sinkholes are depressions or holes in the land surface that occur throughout west-central Florida. They can be shallow or deep, small or large, but all are a result of the dissolving of the underlying limestone.Many of the lakes in Florida are sinkholes. Sinkholes can be classified as geologic hazards sometimes causing damage to structures and roads resulting in costly repairs. Sinkholes can also threaten water supplies by draining unfiltered water from streams, lakes and wetlands directly into the aquifer (underground water supply) .http://www.dep.state.fl.us/geology/geologictopics/sinkhole.htm []
