← GeographyWhich outcome commonly occurs as rising sea temperatures change thermal stratification near island coasts?
A)Increased intensity of coastal upwelling✓
B)Formation of new sand barrier islands
C)Reduced frequency of harmful algal blooms
D)Decreased rate of shoreline erosion
💡 Explanation
Increased sea temperatures sharpen stratification producing density differences that intensify upwelling currents along coasts because the thermocline becomes a strong boundary driving the process, therefore enhancing upwelling and nutrient supply, rather than decreasing erosion which involves wave action independently.
