A sinkhole is a natural depression or hole in the Earth's surface caused by karst processes for example, the chemical dissolution of carbonate rocks or suffosion processes in sandstone.

A sink hole is formed when any underground cavern becomes large enough that the weight of its roof becomes too much for the ground to support. The resultant collapse creates a depression on the surface that is the sink hole. Normally sink holes develop in limestone areas were caverns become larger and larger. But they can happen in any soluble rock. They can even be created when an underground water pipe breaks. The rushing water excavates out a large void that eventually collapses.

A sinkhole, also known as a sink, shake hole, swallow hole, swallet, doline or cenote, is a natural depression or hole in the surface topography caused by karst processes - the chemical dissolution of carbonate rocks,Sinkholes may vary in size from less than 1 to 300 meters (3.3 to 980 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. They may be formed gradually or suddenly, and are found worldwide. These terms are often used interchangeably, though many distinguish between features a surface stream flows into and features with no such input. Only the former are described as sinks, swallow holes or swallets. A sinkhole on a glacier is a moulin or glacier mill.A sink hole is the erosion of land. It forms when underground
water dissolves minerals in the ground. This creates a buried hole. Eventually, the hole becomes large enough that the land on top caves in. Sinkholes are common in land containing limestone, because limestone is soft and ...more
