← GeographyWhich mechanism prevents ceiling collapses in solution caves?
A)Bridging from mineral precipitation✓
B)Buoyancy from hydrothermal vents
C)Elastic deformation of ceiling layers
D)Capillary action in porous rock
💡 Explanation
Mineral precipitation within cave formations creates bridges, increasing structural integrity; therefore, this bridging prevents collapse, rather than buoyancy or rock deformation alone, because they cannot counteract gravity and erosion effectively.
