← GeographyWhich mineral resource accumulation concentrates within subtropical ocean gyres where Ekman transport converges debris?
A)Manganese nodules in abyssal plains
B)Rare earth elements absorbed in sediments✓
C)Phosphate-rich volcanic seamounts
D)Iron concretions near hydrothermal vents
💡 Explanation
When surface currents in subtropical gyres converge, Ekman transport drives floating microplastics inward because of Coriolis forces, providing a matrix for rare earth element absorption in surrounding sediments. Therefore rare earth elements concentrate, rather than manganese, phosphate, or iron, which require different geological conditions.
