Which mechanism prevents full cavern collapse after extensive limestone dissolution?

💡 Explanation

Secondary mineral deposition adds new mass to the cave ceiling through chemical precipitation, strengthening the overhead arch, because this opposes the force of gravity; therefore arches resist collapse rather than experience it because isostatic rebound acts over geologic time.
