Geologists divide sinkholes into three types. The first is a dissolution or solution sinkhole. In this type of sinkhole, there is little soil or vegetation over the limestone or other bedrock. Water from rain and runoff slowly trickles through crevices in the bedrock, dissolving it.As a result, a depression gradually forms.arning signs of sinkholes. Areas with underlying dissolvable rock are most susceptible to sinkholes. According to the USGS, the most dangerous spots are in Florida, Texas, Tennessee, Pennsylvania, Alabama, Missouri and Kentucky. There are often warning signs before a sinkhole collapse, however.
