← GeographyWhich impact occurs on global nutrient distribution due to El Niño?
A)Suppressed South American coastal upwelling✓
B)Increased Antarctic bottom water formation
C)Strengthened North Atlantic deep water sinking
D)Enhanced equatorial deep ocean mixing
💡 Explanation
El Niño suppresses upwelling off South America due to weakened trade winds, leading to warmer surface waters; this causes reduced nutrient availability because nutrient-rich deep water doesn't reach the surface and supports fisheries, therefore A rather than B/C/D.
