← GeographyWhich outcome primarily occurs due to weakened gyre circulation?
A)Reduced nutrient upwelling intensification✓
B)Increased deep ocean stratification
C)Enhanced coastal erosion rates
D)Accelerated glacial melting feedback
💡 Explanation
Reduced gyre circulation weakens the Ekman transport, decreasing upwelling of nutrient-rich waters to the surface because convergence is reduced, therefore declining vital nutrient availability for marine ecosystems, rather than causing the stated alternatives related to stratification, coastal erosion, or positive feedback cycles.
