Question

Which of the following ocean current is NOT a cold current?

• A. Peruvian Current
• B. Antarctica Current
• C. Oyashio Current
• D. Kuroshio Current

Hint:

Remember: Currents flowing towards the equator are usually cold (carrying polar water). Currents flowing away from the equator are usually warm (carrying tropical water). Kuroshio flows away from the equator towards the north.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks to identify the warm ocean current among a list that primarily contains cold currents. Ocean currents play a massive role in distributing nutrients and determining the productivity of fishing grounds.

Step 2: Detailed Explanation:

• Kuroshio Current: This is a Warm Current in the western North Pacific Ocean. It flows northward along the coast of Japan. It is the Pacific counterpart of the Atlantic's Gulf Stream. It carries warm, tropical water to higher latitudes, which is why it is not a cold current.

• Peruvian Current (Humboldt Current) (Option A): A major Cold Current that flows northward along the western coast of South America. It is famous for the upwelling of nutrient-rich deep water, supporting the world's largest anchovy fishery.

• Oyashio Current (Option C): A Cold Current that flows southward from the Arctic through the Bering Sea into the North Pacific. The meeting of the cold Oyashio and the warm Kuroshio creates one of the richest fishing grounds in the world near Japan.

• Antarctica Current (West Wind Drift) (Option B): A powerful Cold Current that flows clockwise around Antarctica.

Step 3: Final Answer:
The Kuroshio Current is NOT a cold current; it is a warm current.
