In Some Regions Groundwater Withdrawals Can Contribute To Sinkholes, In Which "What"?From Earth Sciences & Geology Forum:
In some regions groundwater withdrawals can contribute to sinkholes, in which "what"? A.Small (about 3 feet across) holes start appearing in the ground B.Empty underground caverns suddenly collapse C. Buildings slowly settle at odd, perilous angles D. Ground level over a large area sinks E. Holes for wells need to be deeper and deeper because of a change in the water table
Answer: Well, I think here the question is: "what is a sinkhole," as opposed to "what happens during groundwater fluctuation in a karts aquifer". Given this, a sinkhole is B - empty groundwater caverns suddenly collapse.
What Is A Sinkhole? How Is It Formed?From Earth Sciences & Geology Forum:
What is a sinkhole? How is it formed?
Answer: Sinks holes form from dissolution of limestone(CaCO3). Rain water or ground has a pH level(HCL) that breaks down the limestone. When the water level drop because the limestone has been broken down it is no longer competent to support itself, therefore the weight the rock layer sinks in the cavern below the lime stones. The caverns form from the Di solution of Limestone(CaCO3)
What Is A Sinkhole?From Earth Sciences & Geology Forum:
What is a Sinkhole? I what to know when they started calling it,when it first happen,and who started using that word.
Answer: The first time I heard about a sinkhole was in the 1970's when a place in Florida swallowed a house. I think the term sinkhole is a lot older than that, though. It came from Middle English sinker Hill which is going back a long way. However, the original meaning of sinkhole was a cesspool where all the drainage of waste accumulated. During the Great Depression of the 1930's it was used to describe a place where all things undesirable and evil gathered. It also means a financial venture that makes no profit and eats up all your capital. I couldn't find any reference as to when they started using the term in geological reference.

What Is A Sinkhole And How Many Deaths Occur Each Year Because Of This?From Geography Forum:
what is a sinkhole and how many deaths occur each year because of this?
Answer: Sinkholes, also known as sinks, shake holes or doling (in the Slovene language doling means valleys), and centers, are a feature of landscapes that are based on limestone bedrock. They are found worldwide. One form is the collapse of a cave roof. The result in this case is a depression in the surface topography. This may range anywhere from a small, gentle earth-lined depression, to a large, cliff-lined chasm. Most often there is a small area of rock exposure near or at the bottom of a sinkhole, and a patent opening into the cave below may or may not be visible. In the case of exceptionally large sinkholes, such as Cedar Sink at Mammoth Cave National Park, there may actually be a stream or river flowing into the bottom of the sink from one side and out the other side. Sinkholes often form in low areas where they form drainage outlets for a running or a standing water. They may also form in currently high and dry locations. Florida has been known for having frequent sinkholes, especially in the central part of the state. Sinkholes are usually but not always linked with a karts landscape. Karts represents a set of surface features that are characteristic of limestone under the soil. In many such regions, there may be hundreds or even thousands of sinkholes in a small area so that the surface as seen from the air looks pock-marked. Often in such areas there are few or no flowing streams on the surface because the drainage is all sub-surface. Sinkholes have for centuries been used as disposal sites for various forms of waste. A consequence of this is the pollution of groundwater resources, with serious health implications in such areas. Sinkholes also form from human activity, such as the rare but still occasional collapse of abandoned mines in places like West Virginia. More commonly, sinkholes occur in urban areas due to water main breaks or sewer collapses when old pipes give way. They can also occur from the over pumping and extraction of groundwater and subsurface fluids. Natural sinkholes can be very deep, offering extremely challenging conditions for adventurous and experienced divers. Some of the most spectacular are the Acton center in Mexico, the Baseman's sinkhole in South Africa, Sarisariñama tepee in Venezuela and in the town of Mount Gamier, South Australia-.
