Which risk notably increases as waves persistently exploit weaknesses within coastal sea stacks?

💡 Explanation

Catastrophic structural destabilization increases because hydraulic action widens fractures initiating sudden collapse; continued erosion leads to toppling therefore quick stack disintegration rather than slower weathering processes under stable conditions.

• Which effect primarily shapes soil structure due to intensive earthworm activity?
• Which outcome occurs when flood control levees constrict channel width?
• Which mechanism amplifies temperature gradients at mid-latitudes when polar Hadley cell boundaries shift equatorward?
• Which topographical consequence results when permafrost soil exhibits heightened instances of bioturbation?
• Which atmospheric effect increases when high orographic relief disrupts Hadley cell circulation?
• Which hazard increases where soluble bedrock collapses suddenly?
