Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.
Sinkholes occur worldwide; Texas is one of the U.S. âhot spotsâ for sinkholes. Structures built on limestone and sandstone bedrock can be especially vulnerable. Acidic water from rain and ruptured pipes can erode the bedrock, forming cavities. A sudden influx of rain after a dry period can trigger development of sinkholes.
