How do sinkholes form?

Sinkholes typically form in karst landscapes where acidic ground water runs into the bedrock, dissolving the rock while creating cavities and caves that can collapse.

Sinkholes may trap surface drainage from standing or running water, but they may also occur in high and dry places.

They are a natural occurrence, but can also be caused by human influences. People building homes, stores or retention ponds on fragile land can cause sinkholes to form.
The pumping of water from aquifers lowers the water table, which can also accelerate the creation of sinkholes.

In urban areas, sinkholes can occur from breaks in water mains or from sewer collapses.

Sinkholes can happen to anybody at any time. Let's be careful out there!

Not only pumping it can destroy it but Imagine a water main break. (Our national inferstuction scored a D on a report card in 2016) broke. All that water flushing away sand based soil in Florida from underneath the building or house etc. Creates a major sinkhole. It can happen in any soil but im talking about Florida for right this second. Sand is that last type of soil you use for a strong long-term structure you want . Fyi we do use a layer of sand but it's just a layer not the foundation

I have a huge fear of falling into one of these 😭

What about the cemetery's in Florida? Will the caskets sink?

The thing is: the rainwater (heavy or not) should be accounted for when designing these pipes. I hope you know our rain water is collected into stormwater pipes underground. If those pipes are not maintained or not designed right, then it is a human or city cause.

If for example the groundwater caused the sinkhole, then its an act of God.
