What is a sinkhole?
A sinkhole is a hole or depression in the earth's surface often associated with glacial terrain. Sinkholes can vary in size from about 3 meters to 600 meters. They can form gradually or can occur suddenly in rocks that naturally be dissolved by water circulating through them. This creates voids in the rock that can cause the rock to collapse. Many processes can lead to sinkholes. Erosion, lowering the level of groundwater, or the collapsing of a cave can all lead to the formation of sinkholes.
