That Sinking Feeling

Published 5/7/2009 - Firstcoastnews.com
According to researchers at the University of Florida, "Sinkholes originate beneath the surface when groundwater moves through the limestone and erodes large voids, or cavities, in the bedrock. When water fills a cavity, it supports the walls and ceiling, but if the water table drops, the limestone cavity is exposed to further erosional processes that eventually result in the collapse of the cavity, causing a sinkhole."

Sinkholes can be found around the world, but because of Florida's unique subsurface structure of limestone, mineral deposits and flowing water underground, Florida has the highest amount of sinkholes in the U.S.
