Geography

Choose the Correct Answer

Correct Answer : Option b

Explanation
Statement 1 is not correct: The Andaman and Nicobar Islands were not entirely formed by volcanic activity. They mainly resulted from tectonic movements, where the Indian Plate is sliding under the Burmese Plate. The entire group of islands is divided into two broad categories: the Andaman in the north and the Nicobar in the south. It is believed that these islands are an elevated portion of submarine mountains. However, Barren Island, part of the Andaman group, is India’s only active volcano and was formed by volcanic activity.

Statement 2 is Correct: Great Nicobar Island has been recognized as part of UNESCO's World Network of Biosphere Reserves due to its rich biodiversity and ecological significance.

Statement 3 is not correct: Little Andaman is not separated from Nicobar by the Nine Degree Channel. It is actually separated by the Ten Degree Channel.

Other Channels
● Nine Degree Channel: Separates Lakshadweep’s Kavaratti Island from Minicoy Island.
● Eleven Degree Channel: Separates some of the Andaman Islands, such as Little Andaman, from the rest of the Andamans.
● Eight Degree Channel: Lies between India’s Minicoy Island (Lakshadweep) and the Maldives
