A sinkhole is any hole in the ground created by subterranean erosion or solution of rock due to the activity and drainage of water. They can be just a few feet across or large enough to swallow whole buildings.
There are two types - those that form slowly starting with gradual subsidence and those that form suddenly by catastrophic collapse of cavern roofs.
They are common in wet climates where the subsurface rocks are soluble (gypsum/dolomite/limestone).

How do sinkholes form?
Sinkholes are formed when the supporting water table runs dry and the ground no longer has this strata to stand on. This happens in the states of Florida and Georgia in the US because they have more underground rivers than most. The ground simply collapses down the now dry rivers that were once filled with water. These are the first real signs of a major drought.
