Which geological consequence results during extreme El Niño years due to increased equatorial rainfall?

💡 Explanation

When strong El Niño events cause increased equatorial rainfall, wave action intensifies and storm surges become more pronounced along normally arid coastlines because increased precipitation directly affects coastal dynamics. Therefore accelerated coastal erosion is a consequence, rather than changes in rivers, seismicity or upwelling which have distinct mechanisms.

• Which mechanism contributes when variations occur with the Walker circulation's wind patterns in the tropical Pacific region?
• Which outcome occurs when groundwater exploitation exceeds recharge in an alluvial aquifer?
• Which effect increases when coastal upwelling intensifies parallel to the shoreline above a fishing ground?
• Which effect results when seasonal cave flooding mobilizes sediments?
• Which process accelerates when a river erodes the neck of an oxbow lake during flood stage?
• Which mechanism maintains stable North Atlantic thermohaline circulation despite freshwater input from glacial melt?
