89. Oh certainly more acid rainwater contributes
And in some areas, like up here around Tallahassee, there is a clay layer with acidic clay above the limestone. But since the clay tends to retain moisture, the limestone layers underneath are less likely to dry and break.

Most sinkholes are more like the one on the right in your picture or may not even drop enough to become a hole, just a depression. A few are like the one in the middle. When ocean levels are lower, as they were in the past, or ground and aquifer water levels reduced from drought or too much pumping as in Plant City last January, the limestone caverns are not supported by the water. Dry limestone is more brittle and more likely to collapse under the weight of the ground above. That is why you usually see more sinkholes during a drought.
