What is the basic difference between vadose and phreatic cave passages in karst?
Answer and explanation
Correct answer: Vadose passages form above the water table by flowing water and phreatic passages form under fully water-filled conditions
Vadose passages develop above the water table, where gravity-driven streams usually cut downward through limestone and produce more vertically developed channels. Phreatic passages form below the water table while the conduit is completely filled with groundwater; dissolution can then occur around the passage in several directions. Hence option A is correct. The remaining choices confuse karst drainage with wind, glacial, marine, or drumlin processes.
