SINKHOLE
Sinkhole
A sinkhole, also known as a sink-hole, sink, swallow hole, shakehole, swallet or doline, is a natural depression or hole in the ground caused by some form of collapse of the surface layer. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes in sandstone. Others formed as a result of the collapse of old mine workings close to the surface are not natural and therefore not sinkholes.The above text is a snippet from Wikipedia: Sinkhole
