Consider the following oceanic currents : I. Oyashio II. Canaries III. Labrador IV. Kuroshio V. Benguela VI. Alaska VII. Humboldt How many of the above are Pacific Ocean currents?
- A.One
- B.Two
- C.Three
- D.Four
Correct answer
Explanation
The correct answer is D, Four. Oyashio, Kuroshio, Alaska and Humboldt are currents of the Pacific Ocean, while Canaries, Labrador and Benguela flow in the Atlantic.
In the North Pacific, the warm Kuroshio flows north-east past Japan and meets the cold Oyashio coming down from the Bering Sea; their meeting off Japan makes rich fishing grounds. The warm Alaska Current circles the Gulf of Alaska. In the South Pacific, the cold Humboldt or Peru Current flows north along the coast of Chile and Peru. In the Atlantic, the cold Canaries Current flows past north-west Africa, the cold Labrador Current comes down past Canada, and the cold Benguela Current flows along south-west Africa.
A is wrong because more than one listed current lies in the Pacific. B is wrong because it misses two of the four Pacific currents. C is wrong because it leaves out one of Oyashio, Kuroshio, Alaska and Humboldt.
Exam tip: Kuroshio and Oyashio meet off Japan; Gulf Stream and Labrador meet off Newfoundland.
