Identify 3 common features of karst topography?

Karst topography is characterized by features such as sinkholes, which are depressions or holes formed when underground limestone dissolves. Another common feature is limestone caves, created by the erosion of soluble rock, often leading to spectacular stalactites and stalagmites. Additionally, karst regions often exhibit underground drainage systems, where surface water flows into the ground, creating a unique hydrological landscape.
