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.
The exact number of sinkholes in the world is difficult to determine, as they can occur in various locations and sizes, often going unreported. Sinkholes can develop in regions with limestone bedrock, where water erosion occurs, and they can appear suddenly. While some areas, like Florida in the United States, are particularly prone to sinkholes, they can happen anywhere with the right geological conditions. Overall, thousands of sinkholes are reported globally each year.
The number of sinkholes that occur each year varies significantly by region and environmental conditions. In the United States, it's estimated that thousands of sinkholes can occur annually, with Florida being particularly prone due to its limestone bedrock. Globally, the frequency can range from hundreds to thousands, depending on geological factors and human activity. However, precise statistics can be challenging to obtain, as many small sinkholes go unreported.
Sinkholes are perminant but usually get filled in with debrie or dirt. Also sinkholes can become small ponds depending on the size.
Sinkholes are most common in countries with limestone or other soluble rocks that are prone to dissolution. Countries such as the United States, Mexico, China, and Australia have reported frequent occurrences of sinkholes due to geological conditions like karst topography.
The Yucatan Peninsula. These "sinkholes" are called "cenotes" over there.

Sinkholes form when limestone dissolves and pores and cracks grow bigger.
Sinkholes commonly occur in areas with soluble bedrock, such as limestone, gypsum, or salt. This geological condition is prevalent in regions known as karst landscapes, which can be found in places like Florida, Texas, and parts of the Mediterranean. Additionally, urban areas with heavy groundwater extraction or poor drainage systems are also prone to sinkhole formation. The combination of natural and human factors contributes to the frequency of sinkholes in these locations.
Sinkholes cause flooding, underground system damage, building damage, and human casualties.

Humans adapt to sinkholes by implementing infrastructure designs that account for the presence of sinkholes, such as diversion structures and reinforced foundations. Monitoring and early detection systems can also help reduce the risks associated with sinkholes. Additionally, educating communities on the potential dangers and providing resources for mitigation efforts can further help adapt to sinkhole-prone areas.
