What explains the eastward flow of the equatorial counter-current?
Pick an option to check yourself. The answer stays hidden until you attempt.
• Correct Answer: B
• Convergence of westward equatorial currents creates water pile-up in western ocean basins, generating a pressure gradient that drives eastward return flow.
• Trade winds cause accumulation; excess water flows eastward through the Doldrums zone.
• Earth's rotation influences direction but does not cause the eastward flow itself.
