Andaman Quiz

Notes:
The correct answer is [C] 3 and 4 only. This question tests geographical knowledge of major world rivers and their respective drainage basins or discharge points.

• Mekong – South China Sea (Pair 1 – Incorrect): The Mekong River originates in the Tibetan Plateau, flows through Southeast Asia (Myanmar, Laos, Thailand, Cambodia), and empties into the South China Sea through the Mekong Delta in Vietnam, not the Andaman Sea.
• Thames – North Sea (Pair 2 – Incorrect): The River Thames flows through southern England, including London, and empties into the North Sea via the Thames Estuary. The Irish Sea lies to the west of Great Britain.
• Volga – Caspian Sea (Pair 3 – Correct): The Volga is the longest river in Europe. It flows through central Russia and discharges into the Caspian Sea. It is a closed (endorheic) basin.
• Zambezi – Indian Ocean (Pair 4 – Correct): The Zambezi is the fourth-longest river in Africa. It flows through several countries (including Zambia, Angola, and Zimbabwe) and empties into the Indian Ocean in Mozambique. It is famous for the Victoria Falls.

Key Fact: The Mekong is often called the “Danube of the East” due to its importance for trade and biodiversity in Southeast Asia. The Volga carries roughly 80% of the total river inflow into the Caspian Sea, significantly influencing its salinity levels.

Notes:
The correct answer is [A] 1, 2 and 3 only. This question tests your knowledge of the specific marine ecosystems and “Marine Protected Areas” (MPAs) along the Indian coastline.Why 1, 2, and 3 are Correct:India has four major coral reef regions, characterized by different types of reef structures (Fringing, Barrier, and Atoll):

• Andaman and Nicobar Islands (1): These islands possess the most pristine and diverse coral reefs in India. They are primarily fringing reefs that surround the islands, hosting hundreds of species of hard and soft corals.
• Gulf of Kachchh (2): Located in Gujarat, this region contains the northernmost reefs in India. These are mainly fringing reefs. The area is protected as the Marine National Park and Sanctuary.
• Gulf of Mannar (3): Situated between India and Sri Lanka (Tamil Nadu coast), this is a Biosphere Reserve. It contains a chain of 21 islands with extensive fringing reef structures.
• Lakshadweep (Not in options but relevant): This is the only region in India with atoll reefs (ring-shaped reefs surrounding a lagoon).

Why Sunderbans (4) is Incorrect?

• The Sunderbans is the world’s largest mangrove ecosystem, formed by the delta of the Ganga, Brahmaputra, and Meghna rivers.
• Coral Requirements: Corals require clear, saline, and shallow water with very low turbidity (sediment) to survive. The Sunderbans region is characterized by massive amounts of freshwater discharge and silt/sediment from the river systems. This makes the water murky and less saline, conditions that are lethal to coral polyps.

Summary Table of Indian Coral Reefs:

Location	Type of Reef	Key Feature
Andaman & Nicobar	Fringing	Highest biodiversity in India
Gulf of Mannar	Fringing	Part of a UNESCO Biosphere Reserve
Gulf of Kachchh	Fringing	Northernmost, high stress-tolerant corals
Lakshadweep	Atoll	Built on volcanic mountain tops

Notes:
The correct answer is 2 only. To understand why, we have to look at the geography of the maritime “choke point” known as the Strait of Malacca and the proposed alternatives.

• Deepening the Malacca Straits (Statement 1 is Incorrect): The Strait of Malacca is already the primary shipping lane between the Indian Ocean and the Pacific Ocean. While deepening the strait might allow larger ships (with deeper drafts) to pass through, it does not change the distance or the geographic path a ship must take. A ship still has to sail all the way down around the Malay Peninsula and back up into the South China Sea. Therefore, it does not reduce navigation time or distance; it only increases the capacity for larger vessels.
• The Kra Canal Project (Statement 2 is Correct): The Kra Isthmus is the narrowest part of the Malay Peninsula in Thailand. Opening a canal here (similar to the Suez or Panama Canals) would allow ships to bypass the entire Malay Peninsula and the Strait of Malacca. This “shortcut” would connect the Andaman Sea directly to the Gulf of Thailand (Gulf of Siam), cutting the journey by approximately 1,200 kilometers and saving several days of navigation time.

Notes:
Statement 1 is incorrect because biodiversity hotspots are not exclusively located in tropical regions; they also exist in temperate and Mediterranean climates. Statement 2 is also incorrect; India’s recognized biodiversity hotspots include the Western Ghats, Eastern Himalayas, Indo-Burma, and Sundaland, not Western Himalayas separately or Andaman and Nicobar Islands. Hence, both statements are inaccurate.

Notes:
Saltwater crocodiles (Crocodylus porosus) are native to the Andaman and Nicobar Islands, inhabiting coastal estuaries, mangroves, and rivers. Statement 2 is incorrect because while shrews occur in the Western Ghats, tapirs are not found in India, being native to Central/South America and Southeast Asia. No tapir species exist in the Western Ghats or mainland India according to mammal checklists.

Notes:
Pandu Bhorji, Dharma Subhan, and Dhindi Birbal were all revolutionary activists from Maharashtra involved in anti-British activities. Each was arrested by the British colonial authorities and sentenced to the Cellular Jail in the Andaman Islands, known as “Kala Pani”. These individuals represented different regions: Pandu Bhorji from Ahmednagar, Dharma Subhan from Pandharpur, and Dhindi Birbal from Nashik, all centers with significant revolutionary history. Their imprisonment at Cellular Jail reflects their active resistance and contribution to the Indian independence movement. Historical records confirm that all three suffered long-term incarceration for their defiance against British rule.

Notes:
Recently, the Chief of Defence Staff inaugurated a major runway upgrade at the Indian Air Force base on Car Nicobar Island. Car Nicobar Island is part of the Nicobar district in the Andaman and Nicobar Islands Union Territory. It is the northernmost island of the Nicobar group, lying south of Little Andaman and north of Nancowry Island. The Ten Degree Channel separates the Andaman Islands and Nicobar Islands near the island. Despite its small size of under 127 square kilometres, it holds nearly half of Nicobar’s population and serves as the district headquarters.

Notes:
Vinayak Damodar Savarkar wrote “Hindutva: Who is a Hindu?” in 1923 while imprisoned in the Cellular Jail, Andaman Islands. The work defined Hindutva and profoundly influenced Hindu nationalist ideology. The Cellular Jail is now a national memorial of India’s freedom struggle.

Notes:
Recently, the Andaman and Nicobar Islands administration set up a Van Dhan Vikas Kendra for the Onge tribe at Dugong Creek under the Pradhan Mantri Janjati Adivasi Nyay Maha Abhiyan. This aims to make the Onges self-sustainable through coconut-based products. The Onges are among the most primitive tribes in India from the Negrito racial stock. They live on Little Andaman Island, the southernmost island of the Andaman archipelago. Onges are semi-nomadic and fully depend on natural food sources.

Notes:
Recently, Lieutenant General Dinesh Singh Rana took charge as the 18th Commander-in-Chief of the Andaman and Nicobar Command (CINCAN). The Andaman and Nicobar Command (ANC) is India’s first integrated theatre command, established in 2001. It is headquartered in Port Blair and integrates the Army, Navy, Air Force, and Coast Guard. The command plays a crucial role in securing India’s strategic interests in the Indian Ocean Region. The post of Commander-in-Chief Andaman and Nicobar Command (CINCAN) rotates among the three armed services.
