Which of the following ocean currents is associated with the Indian Ocean?
- A.Florida current
- B.Canary current
- C.Agulhas current
- D.Kurile current
Correct answer
Explanation
The correct answer is C, the Agulhas current. It is a warm current of the Indian Ocean that flows southward along the eastern coast of southern Africa, carrying tropical water towards the Cape before most of it turns back into the Indian Ocean. Along with the Mozambique and West Australian currents it makes up the southern Indian Ocean gyre.
Option A, the Florida current, belongs to the Atlantic; it carries water out of the Gulf of Mexico past Florida and feeds the Gulf Stream. Option B, the Canary current, is also Atlantic, a cold current flowing south along the north-western coast of Africa past the Canary Islands. Option D, the Kurile or Oyashio current, is a cold current of the northern Pacific that flows south past the Kurile Islands towards Japan, where it meets the warm Kuroshio.
