How are sinkholes in Florida commonly formed?
The conditions are just right for sinkholes in Florida. Most rainwater is slightly acidic and becomes more acidic as it moves through decaying plant debris in Florida’s soils.

Why do sinkholes are eating Florida?
Why Sinkholes Are Eating Florida. The water in aquifers also exerts pressure on the limestone and helps to stabilize the overlying surface layer, usually clay, silt and sand in Florida. Sinkholes form when that layer of surface material caves in. The collapse can be triggered by a heavy overload, often caused by a downpour or flooding,…
Why does Florida keep getting sinkholes?
Sinkholes are common in Florida because the bedrock underlying most of the state is either limestone or dolostone, which is naturally soluble and is easily dissolved by rainwater and groundwater. But sinkholes are also common in other areas of the United States and all over the world.
