Which outcome is intensified by increased Equatorial upwelling during La Niña?

💡 Explanation

La Niña strengthens upwelling, which increases the concentration of nutrient-rich deep ocean waters at the surface via advection, because reduced thermocline depth brings up nutrients. Therefore, nutrient concentration increases, rather than decreasing temperatures or causing flooding that characterizes El Niño.

• Which feedback mechanism explains higher sea surface temperatures that disrupt upwelling within an ocean gyre?
• Which outcome occurs when tectonic stress overcomes friction?
• Which outcome increases proportionally with substantial bioturbation in temperate grasslands?
• Which risk increases significantly when heavy pyroclastic flows bury temperate forests?
• Which mechanism maintains lake level stability despite seasonal inflow variation within glacial lakes formed by isostatic rebound?
• Which outcome occurs when the rate volcanic outgassing decreases rapidly before pyroclastic eruptions?
