thumb|The Red Lake (Croatia)|Red Lake sinkhole in [[Croatia]] A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. A cenote is a type of sinkhole that exposes groundwater underneath. Sink and stream sink are more general terms for sites which drain surface water, possibly by infiltration into sediment or crumbled rock.
A doline is a type of enclosed depression or hole in the ground, similar to a sinkhole, that can also be called a shakehole. Dolines matter because they represent natural formations where the ground surface has collapsed, and they can affect land use, drainage patterns, and the landscape in regions where they occur.
