What type of bedrock most likey exists in an area that has numerous sinkholes?

Areas with numerous sinkholes typically have limestone bedrock, as it is prone to dissolution through a process called chemical weathering. This occurs when acidic water percolates through the limestone, creating underground cavities. Over time, these cavities can collapse, leading to the formation of sinkholes. Other soluble rocks, such as gypsum or salt, can also contribute to sinkhole formation, but limestone is the most common.
