Question map
Which one of the following pairs is not correctly matched ?
Explanation
Ocean currents are classified as warm or cold based on their temperature relative to the surrounding water and their direction of flow. Warm currents typically flow from the equator toward the poles, while cold currents flow from high latitudes toward the equator [c4, t8]. The Kuroshio Current is a warm current in the Pacific Ocean that transfers tropical water northwards [t1, t2]. The Benguela Current is a cold current flowing along the west coast of South Africa [t3]. The Oyashio Current is a cold current originating in the Bering Sea [t2, t3]. However, the Labrador Current is a cold current that flows from the Arctic Ocean along the east coast of Canada [c1, c3]. Therefore, the pair 'Labrador: Warm ocean current' is incorrectly matched as it is a cold current that significantly lowers temperatures near the North American coast [c3, t4].
