Which hazard increases when overlying clay erodes above karst?

💡 Explanation

Sinkhole formation increases with the removal of clay overburden by erosion because decreased pressure enhances the dissolution of underlying limestone via chemical weathering, therefore increased vulnerability occurs rather than the development of other geographically distinct or chemically unrelated results.

• Which outcome occurs when crustal subduction ceases at depth?
• Which consequence results when sediment-laden flow exits a constricted canyon onto an unconfined valley floor, exceeding the transport capacity?
• In arid climates, which consequence results when deflation exposes caliche layers?
• Which process dictates whether stick-slip or stable sliding friction dominates the energy release along a tectonic fault line?
• Which risk significantly increases in alluvial aquifers when over-extraction lowers the water table?
• Which consequence results when groundwater table fluctuates substantially in karst landscapes?
