Which of the following are the major coral reef areas of India ? 1. Gulf of Kachchh 2. Gulf of Mannar 3. Lakshadweep 4. Andaman and Nicobar Islands Select the correct answer using the code given below :
- A.1 and 3 only
- B.2 and 4 only
- C.1, 2 and 3 only
- D.1, 2, 3 and 4
Correct answer
Explanation
The correct answer is D, 1, 2, 3 and 4. All four areas are recognised as the major coral reef areas of India.
India's coral reefs lie in four main regions. The Gulf of Kachchh in Gujarat has fringing reefs and the Marine National Park near Jamnagar, India's first. The Gulf of Mannar between Tamil Nadu and Sri Lanka has reefs around 21 small islands and is a biosphere reserve. Lakshadweep is made almost wholly of coral atolls. The Andaman and Nicobar Islands have the richest and most varied fringing reefs in the country. Corals need warm, clear, shallow and salty water, which is why they are absent near large river mouths.
A is wrong: it leaves out the Gulf of Mannar and the Andaman and Nicobar Islands. B is wrong: it leaves out the Gulf of Kachchh and Lakshadweep. C is wrong: it drops the Andaman and Nicobar Islands, the largest reef area of all.
Exam tip: India's four reef areas are Gulf of Kachchh, Gulf of Mannar, Lakshadweep, and Andaman and Nicobar; Lakshadweep is the atoll group.
