When the rock of a cave collapses, it forms a feature known as a "sinkhole" or "cave-in." This occurs when the ceiling of the cave becomes unstable due to erosion, water infiltration, or structural weaknesses, resulting in the sudden dropping of rock and debris. The collapse can create an opening at the surface, potentially impacting the landscape above and causing hazards for structures nearby. Additionally, this process can lead to the formation of new geological features over time.
