Which risk significantly elevates following prolonged drought cycles in karst landscapes?

💡 Explanation

Increased drought stresses surface soils and increases subsurface erosion; the mechanism is mechanical weathering and material collapsing into solution voids. This accelerates sinkhole formation because soil cohesion reduces, therefore sinkhole formation is increased, rather than more slowly under consistent moisture levels.
