Q. Which of the following is common feature of Indian islands in Arabian Sea?
Answer: Coral origin
Notes: The Indian islands in the Arabian Sea are all of coral origin. These islands are called the Coral Islands of India. The islands were formed by coral accumulating on the volcanic tops of the Indian Ocean ridge. The ridge sank below the surface millions of years ago, likely due to rising sea levels. The Lakshadweep Islands are the smallest Union Territory of India, with a total area of 32 km2 (12 sq mi). Most of the islands are atolls. The islands are flat and have low elevation, rising no more than five meters above sea level. They are vulnerable to sea level change.
