← GeographyWhich outcome is worsened by thermocline breakdown during upwelling?
A)Harmful algal bloom intensity✓
B)Deep sea methane hydrate release
C)Global conveyor belt disruption
D)Submarine volcanic eruption rates
💡 Explanation
Harmful algae bloom intensity worsens because nutrient-rich bottom water is brought in by upwelling and light is present. Because the stability that the thermocline normally provides is reduced through reduced density gradient, this promotes mixing and bloom formation, rather than limiting it.
