Large algal blooms occur when oceanic environments experience which forcing mechanism?

💡 Explanation

Upwelling brings nutrient-rich deep water to the surface, fueling algal growth in illuminated areas because deeper waters have more accumulated decomposed organic matter; therefore, it increases surface productivity rather than relying on volcanic nutrients or thermal convection alone.

• Which outcome occurs when freeze-thaw cycles saturate unconsolidated Arctic soil?
• Which risk significantly increases when coastal upwelling stalls?
• Which outcome slows stalactite growth where CO2 fluctuates?
• Which outcome results from amplified freeze-thaw weathering in cirques?
• Which outcome develops when steady winds erode desert surfaces?
• Which outcome occurs when tectonic plate subduction ceases?
