The islands of Lakshadweep are mainly of which type?
- A.Volcanic islands
- B.Coral islands
- C.Continental islands
- D.River islands
Correct answer
Explanation
The correct answer is B, coral islands. Lakshadweep in the Arabian Sea is made up of coral atolls, reefs and submerged banks built by colonies of coral polyps in warm, shallow and clear tropical water, which is why the islands are low, flat and ringed by lagoons, with Kavaratti as the capital. Option A is wrong because volcanic islands are built by lava from the ocean floor, as at Barren Island in the Andamans or in Hawaii. Option C is wrong because continental islands are detached pieces of a continental shelf, such as Sri Lanka or Greenland, whereas Lakshadweep has no such rocky core at the surface. Option D is wrong because river islands such as Majuli are formed of silt laid down by a river and lie inland, not in the open sea.
