fat people continuously walk over a certain area; over time, the concrete, mortified by what it has seen, develops stress fractures and eventually caves into the soft earth on which it was laid.
They don't. Sinkholes are filled in.
Michigan is a state that is very familiar with sinkholes. On their lower peninsula alone there are close to 200 sinkholes.
subsidence sinkholes are different from collapse sinkholes in two ways . first,subsidence sinkholes ocer when there is almost no overburn,or material,above the limestone. collapse sinkholes happen when there is thick overburn. secondly, subsidence sinkholes occur slowly, over time, while collapse foms quckly beacause of human activity , such as well drilling.
Sinkholes could be prevented, but not without huge expenditures of money.

You can find sinkholes in fl
sinkholes mostly happen at FLORIDA

Sinkholes, as we know it, can affect anyone.
Sinkholes often occur when underground rivers erode the rock beneath the Earth's surface. Eventually, the land above is no longer sufficiently supported and collapses into the cave that has developed beneath it. They are more common in places with limestone, as it is easily eroded.

Sinkholes are perminant but usually get filled in with debrie or dirt. Also sinkholes can become small ponds depending on the size.

The Yucatan Peninsula. These "sinkholes" are called "cenotes" over there.
Sinkholes form when limestone dissolves and pores and cracks grow bigger.
