Q46 (CDS-I/2017) Geography › World Physical Geography › Ocean circulation systems Answer Verified

The Gulf Stream is a poleward flowing current in the Atlantic Ocean. Which one of the following statements with regard to this is not correct?

Result
Your answer: —  Â·  Correct: D
Explanation

The Gulf Stream is a powerful, warm western boundary current in the North Atlantic Ocean that flows poleward from the Gulf of Mexico [1]. It is analogous to the Kuroshio Current in the North Pacific, as both are wind-driven subtropical western boundary currents [2]. The Gulf Stream transports significant volumes of warm tropical water toward higher latitudes [3], which is a major factor in regulating the weather and raising temperatures along the east coast of the USA and Western Europe [2]. However, statement 4 is incorrect because the Gulf Stream is located in the Atlantic Ocean, whereas the West Pacific Coast is influenced by the Kuroshio Current. Coral reefs in the West Pacific are sustained by the warm waters of the Kuroshio and other regional currents, not the Atlantic's Gulf Stream.
