← GeographyWhich ocean current alteration occurs with weakened trade winds?
A)Increased equatorial counter-current strength✓
B)Decreased upwelling along coastlines
C)Strengthened Antarctic circumpolar circulation
D)Intensified North Atlantic Deep Water formation
💡 Explanation
Decreased trade winds reduce surface water piled up in the Western Pacific & Indian oceans; the pressure gradient relaxes, so the Equatorial Counter-Current intensifies. Reduction occurs because weakening wind reduces momentum rather than other large-scale shifts.
