Which risk increases when cave roof support diminishes?

💡 Explanation

The karst window is a result of surface collapse; reduced support allows gravity to exceed material strength, triggering roof collapse. Differential weathering causes erosion, widening joints and fractures that eventually lead to surface breach, rather than other weathering rates.
