← GeographyWhich climate pattern change occurs when equatorial upwelling weakens?
A)Decreased coastal primary productivity✓
B)Increased water column stratification
C)Strengthened prevailing trade winds

💡 Explanation
Reduced upwelling limits nutrient transport, therefore coastal productivity declines because limited nutrients restrict phytoplankton growth through nutrient limitation, rather than increased stability or wind changes.
