Which mechanism exacerbates infrastructure collapse above karst terrain?

💡 Explanation

Infrastructure placed on karst is prone to collapse because **preferential dissolution** widens pre-existing fractures resulting caverns; therefore rapid subsidence occurs rather than gradual settlement typical from soil consolidation.

• Which consequence results when arid region clay deposition exceeds runoff?
• Which outcome occurs as basalt undergoes spheroidal chemical weathering?
• Which outcome increases when highly soluble bedrock groundwater withdrawal exceeds recharge?
• Which mechanism initiates liquefaction during an earthquake when seismic waves propagate through saturated soil?
• Which effect increases nearshore erosion where groynes are constructed perpendicular to prevailing wave direction?
• Which effect occurs when air masses move poleward from subtropical high-pressure zones, deflected by the Coriolis force?
