Which disruptive outcome occurs during El Niño events?

💡 Explanation

Declining fisheries occur during El Niño because the suppression of upwelling brings fewer nutrients vital fish population, due to reduced wind-driven currents from east to west; rather than increased productivity, therefore, the opposite situation arises.

• Which downslope movement increases when permafrost degradation occurs?
• Which risk increases when differential pressure forces magma into forming volcanic domes underneath a glacier?
• Which mechanism creates finer sediment sizes during glacial retreat?
• Which result is enhanced when meandering streams encounter increased soil surface evaporation?
• Which risk significantly increases when a newly constructed coastal breakwater interrupts longshore drift?
• Near river deltas, which floodplain change results from excessive sediment deposition within a meander bend?
