Which outcome results when rising sea levels saturate coastal cave systems?

💡 Explanation

Increased sea levels cause seawater intrusion into coastal caves, increasing the dissolution of limestone via chemical weathering; this destabilizes karst landscapes because the mechanical strength of the rock collapses due to greater porosity; therefore, increased landscape instability occurs, rather than greater stability due to saturation.
