1. Sinkholes are caused when a crack in underground limestone,They appear when the limestone underneath the soil dissolves resulting in a shift or depression in the surface soil.
2. Florida has so many of them because there are a feature of Florida's natural karst topography and the sinkholes provide a primary pathway for rainwater to replenish subsurface groundwater and that is an important part of the aquifer system that supplies 95% of Florida's drinking water.

4. Another hazard besides property damage is price and availability of homeowners insurance. And blocking highways and roads, damaging cars.
