its called KARST TOPOGRAPHY
In places that are mostly humid where Karst topography can usually be found. Karst topography can be best described as landscapes that have underground systems like caves.

Sinkholes are circular to elliptical closed depressions commonly found in karst areas. They form when underground caves collapse due to erosion of soluble rocks such as limestone or dolomite. Sinkholes can vary in size and depth, posing potential hazards to infrastructure and human safety.
The three features that characterize Karst topography are sinkholes (depressions in the ground), caves and underground drainage systems (such as caverns and disappearing streams), and dolines (closed depressions similar to sinkholes but shallower).
An area with many sinkholes is called a sinkhole-prone region. These regions often have underlying soluble rock such as limestone or gypsum that can dissolve over time, leading to the formation of sinkholes. It is important to be cautious in such areas to prevent accidents or property damage.
Swallets are shallow depressions or sinkholes in the ground that can collect and temporary store rainfall or surface runoff. They are typically found in areas with limestone bedrock and are important features in karst landscapes.
In karst areas, this is called a sinkhole.

caverns
Common features in karst topography include sinkholes, caves, underground rivers, and disappearing streams. Karst landscapes are characterized by the dissolution of soluble rocks such as limestone, resulting in unique surface and subsurface landforms.
Limestone
Karst topography is usually formed when acidic water dissolves layers of bedrock. Common attributes include sinkholes and other depressions in the rock.
Karst areas are landscapes characterized by soluble rock formations, such as limestone, that have been eroded by groundwater to create features like sinkholes, caves, and underground drainage systems. These areas typically have unique hydrological processes and are known for their distinctive topography.
