Limestone
most regions do not have limestone under the soil Most regions have rock layers other than limestone
Areas with variable topography (i.e. hills, cliffs, valleys). In places with swift elevation changes or even just hills. These kinds of conditions are shown on the map by the contour lines. When the lines are close together the topography is steep when the lines are further apart the topography is not steep.
Karst topography is a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite.[1]Due to subterranean drainage, there may be very limited surface water, even to the absence of all rivers and lakes. Many karst regions display distinctive surface features, with sinkholes or dolines being the most common. However, distinctive karst surface features may be completely absent where the soluble rock is mantled, such as by glacial debris, or confined by a superimposed non-soluble rock strata. Some karst regions include thousands of caves, even though evidence of caves that are big enough for human exploration is not a required characteristic of karst.
There is not a particular kind of limestone needed to make a canyon or valley. They and caves form through erosion of most limestones, but their development is subject to a good deal of local geological and hydrological control.
Limestone
Not in Orlando proper, but since all of Central Florida and most of the state are karst topography, there are lots of caves in outlying areas, and tons around Gainesville and northern Central Florida.

Most caves are found in areas with limestone bedrock, as it is easily dissolved by water, creating caves through a process called karst topography. These areas include regions like Kentucky in the United States, parts of China, and the Yucatan Peninsula in Mexico.

There are a variety of places throughout the world of course but New Orleans and area are covered in them. Answer: In areas of karst topography, where limestone has been eroded by the acididity and flow of rainwater.

A karst topography is that which composes of limestone and its associated features and structures.•Karst topography and caves develop in limestone rocks due to their solubility in dilute acidic groundwater.•The solubility of limestone in water and weak acid solutions leads to karst landscapes.•Regions overlying limestone bedrock tend to have fewer visible above-ground sources (ponds and streams), as surface water easily drains downward through joints in the limestone.•While draining, water and organic acid from the soil slowly (over thousands or millions of years) enlarges these cracks, dissolving the calcium carbonate and carrying it away in solution.•Most cave systems are through limestone bedrock.•Cooling groundwater or mixing of different groundwater will also create conditions suitable for cave formation.Karst topography occurs when the underlying bedrock is dissolved. The bedrock is made of gypsum, limestone or dolomite. This causes sinkholes and caverns to form.
