USGS Science Feature The Science of Sinkholes. Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them.
A sinkhole can also be known to some as a sink, shake hole, swallow hole, swallet, or doline. A sinkhole typically is a natural depression or hole in the Earth's surface caused by karst processes â the chemical and rapid dissolution of carbonate rocks or processes for example in sandstone.
