What is the function of a ponor in a karst region?
Answer and explanation
Correct answer: To carry surface water into underground passages
A ponor is a natural opening or swallow hole in soluble limestone through which a surface stream disappears underground. It connects the surface drainage network with subterranean channels, caves, and groundwater flow. Option C is correct because the essential function of a ponor is to transfer surface water below ground. Coastal wave refraction, glacial deposition, and deltaic silt spreading are unrelated processes.
