Which biogeochemical outcome results during El Niño events?

💡 Explanation

Reduced coastal upwelling lowers primary productivity because nutrient transport stops; equatorial Walker circulation weakens, suppressing upwelling, therefore less nutrient-rich water reaches surface rather than higher productivity.

• Which outcome occurs when rapid glacial ablation dominates?
• Which risk increases when building foundations sit atop liquefiable soil deposits during an earthquake?
• Which weather outcome emerges when air masses undergo adiabatic cooling at the windward side of extensive mountain ranges?
• Which effect accelerates soil creep downslope where permafrost melts?
• Which mechanism is amplified when climate change warms permafrost surrounding a fjord shoreline?
• Which landscape outcome results when carbonic acid dissolution weakens bedrock?
