← GeographyWhich outcome occurs when an increased rate destabilizes thermoclines?
A)Increased coastal marine productivity✓
B)Decreased dissolved oxygen levels
C)Intensified coastal erosion rates
D)Reduced surface water salinity
💡 Explanation
Increased upwelling can disrupt thermoclines, resulting increased nutrient delivery because the water contains more nutrients; therefore, marine productivity increases near the coast, rather than an increased dissolved oxygen as deeper water is low in oxygen.
