Karst Landscapes
Karst landscapes are unique geographical formations created primarily by the dissolution of soluble rocks, such as limestone, over long periods. This process can lead to features like caves, sinkholes, underground rivers, and distinctive hills called dolines. Rainwater, which becomes slightly acidic as it absorbs carbon dioxide from the air and soil, seeps into cracks in the rock, gradually enlarging them and creating irregular terrains. Karst landscapes are often characterized by their scenic beauty and biodiversity but can also pose challenges for water management and construction due to their unstable ground. Examples include the Mammoth Cave system in the U.S. and the karst regions of Southeast Asia.

Karst landscapes are unique geological formations created primarily by the dissolution of soluble rocks like limestone, gypsum, and salt. This process occurs when acidic water erodes the rock over time, leading to features such as sinkholes, caves, and underground rivers. These landscapes are often characterized by irregular terrain, sharp ridges, and deep valleys. Commonly found in regions with abundant rainfall, karst areas provide crucial habitats and unique ecosystems, but can also present challenges for human activities like construction and water supply due to their complex underground systems.
