← GeographyWhich ecological pattern consistently arises adjacent arid coastal regions as persistent offshore winds drive coastal upwelling?
A)High primary productivity regions✓
B)Extensive coral reef formation
C)Oxygen-depleted dead zone expansion
D)Rapid mangrove forest proliferation
💡 Explanation
When offshore winds act on arid coasts, Ekman transport occurs which brings nutrient-rich deep waters to the surface via upwelling, fueling extensive primary production. Therefore primary productivity increases, rather than coral reefs, dead zones or mangroves, which have different temperature/nutrient needs.
