← GeographyWhich effect on regional climate results when coastal upwelling ceases?
A)Regional sea temperatures will increase✓
B)Salinity rises in surface waters
C)Oxygen concentration rises near shore
D)Plankton blooms substantially decrease
💡 Explanation
Upwelling removes surface heat via vertical transport and mixing, creating a negative forcing; ceasing this mixing causes reduced heat loss and subsequent temperature elevations because convective heat transfer stops, therefore sea temperatures will increase rather than salinity rising or biological productivity being affected.
