Karst• The term "karst" stems from the region Krs in Slovenia, now in
northwestern Yugoslavia, which is typified by stony barren rock
• he Indo- European word "kar" for rock and the Italian word "carso" evolved to the Germanized term"karst," which is now the accepted term for solution-derived landscapes
Ground Water•Vadose zone or Zone of Aeration (Above the Water Table)•Phreatic zone or Zone of Saturation (Below the Water Table)
Karst Topography• Dolomite(CaMg(CO3)2) and Limestone(CaCO3)• Dissolution of rocks (Groud or Surface)
Conditions of Karst Development
• Soluable rock (limestone,dolomite)• Dense highly jointed• Moderate rain fall region
Karst landform• Terra Rosa• Sinkholes• Karst Plain• Stalactites• Stalagmites• Pillars• Karst Solution Valley• Uvala• Polje• Karst Tower• Karst cockpits
Sinkholes• Groundwater dissolves
soluble rock, creating fractures and caves.
• Dissolving continues to form larger caves and fractures.
Polje• A polje is a large flat plain in karst territory, often
structurally controlled

Caverns and cave• Underground spaces• Natural opening in the ground extended beyond the zone of
light
Karst Caverns or Caves• Speleothems• Stalacite• Stalagmites• Pillar• Natural Tunnels• Natural Bridge
