Which term describes a surface current flowing in the opposite direction to an adjacent surface current?

• A. Countercurrent
• B. Eddy
• C. Downwelling
• D. Current

Answer: (A)

A current that flows opposite to a nearby surface current is called a countercurrent. The term highlights the opposing direction of two parallel flows in the ocean, occurring in regions where gyres and wind patterns create adjacent belts moving in opposite ways. For instance, the North Equatorial Current moves westward while the North Equatorial Countercurrent runs eastward above it. This opposite relationship distinguishes it from an eddy (a rotating blob of water), downwelling (vertical sinking of surface water), or a generic current.
