Which of the following is geographically closest to Great Nicobar ?
- A.Sumatra
- B.Borneo
- C.Java
- D.Sri Lanka
Correct answer
Explanation
The correct answer is A, Sumatra. Sumatra in Indonesia lies just across the sea to the south-east of Great Nicobar, the southernmost island of India. Indira Point, the southern tip of Great Nicobar and the southernmost point of Indian territory, is separated from the northern tip of Sumatra by the Six Degree Channel, a stretch of sea less than two hundred kilometres wide. The Andaman and Nicobar chain is in fact the northward continuation of the same submarine mountain arc that runs through Sumatra and Java, which is why the region shares the earthquake belt that caused the 2004 tsunami. Option B is wrong because Borneo lies much farther east, beyond the Malay Peninsula and the South China Sea. Option C is wrong because Java lies south-east of Sumatra, so it is farther away than Sumatra itself. Option D is wrong because Sri Lanka lies far to the west, on the other side of the Bay of Bengal. Exam tip: Ten Degree Channel separates Andaman from Nicobar; Six Degree Channel separates Great Nicobar from Sumatra.
