← GeographyWhich outcome occurs when the Earth's rotation weakens gyre circulation?
A)Localized nutrient redistribution decreases✓
B)Deep ocean water oxygenation increases
C)Equatorial upwelling zones expand
D)Global salinity gradients stabilize greatly
💡 Explanation
Redistribution decreases because weakening gyre circulation reduces wind driven nutrient transport; therefore, less dissolved compounds circulate from the depths and lower latitudes. This occurs rather than increases in oxygen because it restricts transfer, and differs instead from shifts in global salinity distributions.
