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 impact on South American fisheries results when El Niño-Southern Oscillation (ENSO) reduces coastal upwelling?
• Which mechanism causes stream meandering in lowland river systems when cohesive sediment banks are present?
• Which phenomenon results when Earth's rotation causes subtropical atmospheric pressure cells to produce consistent deflection?
• Which process increases mantle plume volcanism at divergent plate boundaries?
• Which outcome occurs when floodplains lack riparian vegetation?
