Explanation: The Andaman and Nicobar Islands are a group of islands located in the Bay of Bengal, forming a union territory of India. These islands are known for their rich biodiversity and unique geographical features, including the presence of an active volcano. The active volcano in this group is located on Barren Island, which is the only active volcano in India.
Barren Island is part of the Andaman and Nicobar Islands and is situated approximately 135 kilometers northeast of Port Blair, the capital of the Andaman and Nicobar Islands. The island is a part of the Andaman volcanic arc, which is a chain of volcanoes that extends from the Andaman Islands to the Nicobar Islands. The volcanic activity on Barren Island is a result of the tectonic activity in the region, where the Indian Plate is subducting beneath the Burma Plate.
The volcanic activity on Barren Island has been recorded since the 18th century, with the most recent eruption occurring in 2017. The island is characterized by its rugged terrain, with a central volcanic crater and several lava flows. The presence of an active volcano on Barren Island makes it a unique geological feature and a significant point of interest for researchers and tourists.
In contrast, the other options listed do not have active volcanoes. Lakshwadeep is a group of coral atolls in the Arabian Sea, Daman and Diu are union territories on the western coast of India, and the Maldives is an island nation in the Indian Ocean composed of coral atolls. None of these locations have any volcanic activity, making the Andaman and Nicobar Islands the only group of islands among the options with an active volcano.
Understanding the geographical features of the Andaman and Nicobar Islands, including the presence of an active volcano, is important for students studying geography, geology, and environmental science. It highlights the diverse geological processes that shape the Earth's surface and the unique characteristics of different regions.
