Quick Summary

The Adriatic Karst is a geological region in southeastern Europe, primarily characterized by limestone bedrock. This type of terrain, known as karst, is formed by the dissolution of bedrock through underground water flow, leading to unique landscapes.

Key features of karst topography include:
* Sinkholes: Depressions in the ground formed by the dissolution of bedrock.
* Underground Streams: Rivers and streams that flow beneath the surface.
* Caves: Natural openings in the earth, often extensive in karst regions.

The Adriatic Karst region, named after the Karst region of the western Balkan Peninsula, extends from Slovenia to Montenegro. Rivers like the Neretva in this area flow largely underground. This geological formation covers approximately 15 percent of the Earth's land surface.123
