← GeographyWhich ecological outcome results from increased upwelling along coastlines?
A)Enhanced marine phytoplankton productivity✓
B)Reduced dissolved oxygen concentration
C)Increased ocean acidification rates
D)Decreased coastal erosion rates
💡 Explanation
When upwelling increases, nutrient-rich water rises to the surface because wind-driven currents move surface water away from the coast, leading to nutrient replacement from the depths. Therefore, enhanced phytoplankton productivity results, rather than reduced oxygen, increased acidification which requires increased carbon dioxide, or decreased erosion without sediment changes.
