RAS question
The Kuroshio Current is a warm current flowing in:
Correct answer: (C) North Pacific along the east coast of Japan.
The Kuroshio Current, or Japan Current, is a warm North Pacific current that flows off the east coast of Japan.
Explanation
The Kuroshio Current is the Japan Current, a warm current of the North Pacific that flows northeastward along Japan's east coast. NOAA's National Ocean Service places the Kuroshio Current off the east coast of Japan, which matches option C. Its exam importance comes from recognising the ocean-basin pattern: like the Gulf Stream in the Atlantic, the Kuroshio is the major warm current on the western side of the North Pacific. This warm flow helps moderate Japan's climate compared with similar latitudes on the Asian mainland. Where it meets the cold Oyashio Current from the north, the contrast helps create rich fishing grounds around Japan.
Why the other options are wrong
- (A) North Atlantic along Europe points to the Gulf Stream or North Atlantic Drift system, not the Kuroshio Current of the North Pacific near Japan.
- (B) The Indian Ocean along East Africa is associated with the Agulhas Current, so it is outside the Kuroshio's North Pacific setting.
- (D) South Pacific along Australia refers to the East Australian Current, which is a different warm current from the Kuroshio.
Concept
This tests the standard World Geography concept of matching major ocean currents with their ocean basin and adjacent coast. It recurs in RAS because currents explain regional climate, fishing grounds and map-based physical geography questions.
