Explanation: The Andaman and Nicobar Islands are a group of islands located in the northeastern part of the Indian Ocean, forming a union territory of India. These islands are part of a submerged mountain range known as the Arakan Yoma, which extends from Myanmar into the Indian Ocean. The Arakan Yoma is a significant geological feature that helps explain the unique topography and biodiversity of the Andaman and Nicobar Islands.
The Arakan Yoma is a mountain range that runs parallel to the western coast of Myanmar, extending into the Indian Ocean. This range is part of the broader Himalayan orogenic belt, which has been formed due to the collision of the Indian and Eurasian tectonic plates. The collision has resulted in the uplift of the Himalayas and the formation of various mountain ranges, including the Arakan Yoma.
The Andaman and Nicobar Islands are a part of the submerged portion of the Arakan Yoma. This means that the islands are the peaks of a mountain range that has been submerged under the Indian Ocean. The geological history of the region is complex, involving the movement of tectonic plates and the formation of mountain ranges over millions of years. The islands are characterized by their rugged terrain, with many hills and mountains, which are remnants of the submerged mountain range.
Understanding the geological context of the Andaman and Nicobar Islands is crucial for comprehending their unique geographical features and biodiversity. The islands are home to a diverse range of flora and fauna, many of which are endemic to the region. The submerged mountain range also plays a role in the ocean currents and marine ecosystems surrounding the islands.
In summary, the Andaman and Nicobar Islands are part of the submerged Arakan Yoma, a mountain range that extends from Myanmar into the Indian Ocean. This geological feature is significant for understanding the topography, biodiversity, and marine ecosystems of the islands. The correct answer is (B) Arakan Yoma.
