← GeographyWhich localized upwelling increase accompanies faster gyre rotation?
A)Sea surface divergence increases✓
B)Deep water salinity decreases
C)Thermocline depth increases locally
D)Coastal erosion sediment decreases
💡 Explanation
Increased gyre speed causes a stronger Ekman transport, thus inducing greater divergence of surface waters farther offshore; this causes localized upwelling because of mass conservation forcing deeper, cooler water upwards, rather than altered salinity or sediment deposition.
