Why can a seasonal lake form in a polje?
Answer and explanation
Correct answer: Because drainage ponors may be blocked or have limited capacity
A polje is a broad, closed karst depression. Water normally leaves through ponors, swallow holes or underground conduits, but these outlets may be blocked by sediment, ice or collapse, or may carry water too slowly during heavy rain. Temporary ponding then creates a seasonal lake, so option B is correct; the other choices involve unrelated coastal, glacial or wind processes.
