The Grand Banks near Newfoundland is one of the world's richest fishing grounds because it is the meeting place of which two currents?
- A.Kuroshio and Oyashio
- B.Gulf Stream and Labrador current
- C.Canary and Benguela currents
- D.Peru and East Australian currents
Correct answer
Explanation
The correct answer is B, the Gulf Stream and the Labrador current. The warm Gulf Stream moving north-east meets the cold Labrador current coming south past Newfoundland. Nutrients carried by the cold water mix with the warmer surface layer, plankton multiplies, and huge shoals of cod once gathered there. The same meeting cools moist air abruptly and makes the Grand Banks one of the foggiest places at sea.
Option A, the Kuroshio and Oyashio, do meet and create an equally famous fishery, but that is off Hokkaido in Japan, not Newfoundland. Option C, the Canary and Benguela currents, are both cold, flow along African coasts thousands of kilometres apart and never meet. Option D pairs a South American current with an Australian one lying in different oceans, so no meeting is possible.
