Sinkholes are depressions in the ground that occur due to the collapse of the surface layer. These natural phenomena are also known as swallow holes, natural wells, or dolines. In some regions, they are called cenotes or uvalas. Sinkholes can be caused by various factors, including natural processes such as the dissolution of limestone or karst rocks, human activities such as mining or drilling, or changes in water levels due to heavy rainfall or drought. Regardless of the cause, sinkholes can be dangerous and damaging to property and infrastructure. Therefore, it is essential to recognize the various synonyms for sinkholes to identify them and take appropriate measures to prevent their formation or mitigate their impact.
