← GeographyWhich consequence results when increased trade wind intensity enhances coastal upwelling?
A)Increased marine primary productivity✓
B)Decreased ocean surface salinity
C)Reduced thermocline stratification
D)Enhanced coastal erosion rates
💡 Explanation
When trade winds intensify, enhanced coastal upwelling occurs as surface waters are driven offshore promoting deeper, nutrient-rich waters to rise because of Ekman transport, fueling phytoplankton growth. Therefore, increased primary productivity occurs, rather than decreased salinity, stratification reduction, or enhanced erosion, all requiring different conditions.
