GEOLOGY

Detailed explanation-1: -The removal of rock in solution allows the development of drainage through the rock, rather than just across its surface as happens largely with rocks removed by mechanical erosion. Consequently, karst landscapes generally lack well-developed surface drainage but have underground drainage conduits, or caves.

Detailed explanation-2: -Features of karst landscapes include caves, springs, disappearing streams, dry valleys, and sinkholes. Acidic groundwater moves through fractures and spaces within the rock, slowly dissolving and enlarging spaces to create larger openings and connected passages.

Detailed explanation-3: -karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.

Detailed explanation-4: -Karst Plateau (Slovene: Kras)(German: Karst), a plateau in southwestern Slovenia and northeastern Italy, which gave the name to karst topography.

Detailed explanation-5: -Karst is a landscape of sinkholes, sinking streams, caves, springs, and other characteristic features.
