← GeographyWhich outcome occurs when trade winds weaken along the equator in the eastern Pacific Ocean, reducing upwelling?
A)Increased surface water temperatures.✓
B)Enhanced nutrient availability.
C)Decreased thermocline depth.
D)Intensified coastal fog formation.
💡 Explanation
When trade winds weaken, upwelling decreases because the driving force that brings cold, deep water to the surface diminishes, causing warmer surface temperatures. Therefore increased temperatures result, rather than enhanced nutrients, shallower thermocline, or coastal fog, which typically involve increased upwelling intensity.
