1. What is the primary geomorphological process?Dissolutional erosion in soluble bedrock by acidic meteoric water
2. What is the characteristic feature?Predominantly vertical shafts with limited horizontal passage
3. How do pit caves form?Pit caves form when rainwater, which has become acidic by picking up carbon dioxide from the air and soil, seeps into cracks in the rock. The acidic water slowly dissolves the rock, widening the cracks into deep shafts.
4. Why are pit caves special for animals?Pit caves are special homes for animals that love darkness. Bats, crickets, spiders, and even special fish live there, and many of them have lost their eyes or color because they don't need them in the dark.
