Karst topography is characterized by features formed due to the dissolution of soluble rocks like limestone, dolomite, and gypsum. One feature of karst topography is the presence of caves. These caves are formed by the dissolution of the rock by acidic water over a long period of time, creating underground caverns and passages. These caves can vary in size and complexity and are a common feature in karst landscapes.
In addition to caves, another feature of karst topography is sinkholes. Sinkholes are depressions or holes in the ground that occur when the roof of a cave collapses, revealing an underground void. They can vary in size from small holes to large depressions that pose risks to structures and landscapes above.
Furthermore, karst topography often includes features such as disappearing streams or springs. Disappearing streams occur when surface water flows into sinkholes or caves, disappearing underground. Similarly, springs can be found in karst areas where water resurfaces from underground caves or passages, sometimes creating unique aquatic ecosystems.
These features collectively contribute to the distinctive landscape of karst regions, showcasing the effects of chemical weathering and erosion on soluble rocks over time.
