Explanation: Barren Island is a significant geographical feature located in the Andaman Sea, which is part of the Indian Ocean. It is the only active volcano in India and is situated approximately 135 kilometers northeast of Port Blair, the capital of the Andaman and Nicobar Islands. The Andaman and Nicobar Islands are a group of islands in the Bay of Bengal, and they are a union territory of India.
The Andaman Sea is a marginal sea of the Indian Ocean, located between the Andaman and Nicobar Islands to the west and the Malay Peninsula and Sumatra to the east. It is a relatively shallow sea, with an average depth of about 1,000 meters. The sea is known for its rich marine biodiversity and is an important area for fishing and maritime trade.
Barren Island, being an active volcano, has erupted several times in the past, with the most recent eruption occurring in 2017. The island is uninhabited due to its volcanic activity, but it is of great interest to geologists and volcanologists. The island's volcanic activity is a result of the tectonic activity in the region, where the Indian Plate is subducting beneath the Burma Plate.
The Andaman and Nicobar Islands, including Barren Island, are part of the Andaman and Nicobar Islands union territory of India. The islands are known for their unique biodiversity, including several endemic species of flora and fauna. The region is also of strategic importance to India, given its location in the Indian Ocean.
In conclusion, Barren Island is correctly located in the Andaman Sea, which is part of the Indian Ocean. This location is significant for understanding the geographical and geological features of the Andaman and Nicobar Islands and the broader Indian Ocean region.
