Which mechanism promotes cave formation where ground saturation fluctuates cyclically?

💡 Explanation

Vadose zone dissolution dominance enlarges fractures during water table cycling because fluctuating saturation increases the aggressive dissolution potential of water. This yields faster cave development, rather than slow hypogenic or epigene processes occurring under steady-state saturated conditions.
