Which one of the following ocean currents is not a warm current?

North Pacific
Falkland
North Equatorial
Canary

The correct answer is (b), Falkland.

The North Pacific, North Equatorial, and Canary currents are all warm currents. The Falkland Current is a cold current.

The North Pacific Current is a warm ocean current that flows northward along the western coast of North America. It is part of the North Pacific Gyre, a large system of rotating ocean currents in the North Pacific Ocean. The North Pacific Current is responsible for bringing warm water from the tropics to the North Pacific, which helps to moderate the climate of the region.

The North Equatorial Current is a warm ocean current that flows eastward along the equator in the Atlantic, Pacific, and Indian Oceans. It is part of the Equatorial Countercurrent, a system of ocean currents that flows in the opposite direction of the trade winds. The North Equatorial Current is responsible for bringing warm water from the tropics to the subtropics, which helps to moderate the climate of the region.

The Canary Current is a cold ocean current that flows southward along the western coast of Africa. It is part of the North Atlantic Gyre, a large system of rotating ocean currents in the North Atlantic Ocean. The Canary Current is responsible for bringing cold water from the North Atlantic to the tropics, which helps to moderate the climate of the region.
