Which one of the following is a cold ocean current ?
- A.Brazilian Current
- B.Gulf Stream
- C.North Equatorial Current
- D.California Current
Correct answer
Explanation
The correct answer is D, California Current. It flows south along the west coast of North America, carrying cold water from higher latitudes towards the equator.
As a rule, currents moving from the poles towards the equator are cold, and those moving from the equator towards the poles are warm. Cold currents usually run along the western coasts of continents in the tropics and subtropics, which is why the California Current, the Humboldt (Peru) Current, the Canary Current and the Benguela Current lie next to dry coasts and deserts. The California Current also brings fog and a cool climate to the coast of California.
Option A is wrong because the Brazilian Current is a warm current flowing south along the east coast of South America. Option B is wrong because the Gulf Stream is a warm current that keeps north-west Europe mild in winter. Option C is wrong because the North Equatorial Current is a warm current flowing west near the equator.
Exam tip: cold currents on west coasts, California, Humboldt, Canary, Benguela, West Australian; warm on east coasts, Gulf Stream, Brazil, Kuroshio, Agulhas.
