1 topicsFrequently Asked Questions
121. What's the most common MCQ trap regarding the Indian Ocean's boundaries?
Students often incorrectly assume the Southern Ocean is the *only* southern boundary. While some definitions use the Southern Ocean, others use Antarctica. UPSC might present options where both are listed, and the correct answer depends on the specific definition being used in the question. Pay close attention to the wording!
Exam Tip
If the MCQ mentions 'according to the International Hydrographic Organization', then the Southern Ocean is the boundary. Otherwise, Antarctica is also acceptable.
2. Why is the Strait of Malacca considered such a vital chokepoint, and what percentage of global trade passes through it?
The Strait of Malacca is the primary sea route between the Indian and Pacific Oceans, connecting major Asian economies like China, India, Japan, and South Korea. It's estimated that around 25% of global trade, including a significant portion of oil shipments, passes through it. Its narrow width makes it vulnerable to piracy, terrorism, and geopolitical tensions, hence its strategic importance.
Exam Tip
Remember the approximate percentage: 25%. Also, link Malacca to the Indo-Pacific region in your answers.
3. How does the concept of the 'Indo-Pacific' challenge or expand the traditional understanding of the Indian Ocean's strategic importance?

It reduces congestion on roads and railways, lowering overall logistics costs.
10. Critics argue that India's focus on maritime security in the Indian Ocean is primarily driven by its rivalry with China. How would you respond to this argument?
While China's growing presence in the Indian Ocean is a factor, India's focus on maritime security is also driven by other factors: (1) Protecting its own trade routes and energy supplies, (2) Countering piracy and terrorism, (3) Providing humanitarian assistance and disaster relief, (4) Upholding a rules-based maritime order. India's approach is multi-faceted and aimed at ensuring the stability and security of the entire region, not solely focused on countering China.
11. What are the key challenges India faces in balancing its economic interests with its environmental responsibilities in the Indian Ocean?
India faces the challenge of balancing its need for economic growth with the need to protect the Indian Ocean's fragile ecosystem. Key challenges include: (1) Managing overfishing and promoting sustainable fisheries, (2) Reducing plastic and industrial pollution, (3) Mitigating the impacts of climate change on coastal communities, (4) Ensuring responsible seabed mining. Balancing these competing interests requires strong regulations, effective enforcement, and international cooperation.
12. Why do students often confuse the Strait of Hormuz with the Strait of Malacca, and what is the correct distinction?
Both are vital chokepoints, but they are geographically distinct and carry different types of cargo. The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea, and is crucial for oil exports from the Middle East. The Strait of Malacca, as mentioned earlier, connects the Indian and Pacific Oceans and carries a more diverse range of goods. Remembering their locations and primary cargo types is key.
Exam Tip
Think: Hormuz = Oil from the Middle East. Malacca = Everything else between India and the Pacific.
