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 unique geographical features and rich biodiversity. In December 2004, a massive tsunami struck the region, causing significant damage and changes to the landscape of the islands.
The tsunami was triggered by a powerful earthquake off the coast of Sumatra, Indonesia, and its effects were felt across the Indian Ocean, including the Andaman and Nicobar Islands. The tsunami waves reached heights of up to 10 meters in some areas, leading to widespread destruction and loss of life.
One of the most significant impacts of the tsunami was the submergence of parts of the Andaman and Nicobar Islands. Indra Point, which is the southernmost point of the Andaman and Nicobar Islands, was particularly affected. The tsunami caused parts of Indra Point to be submerged under water, altering the geography of the area.
It is important to understand the geographical context of the Andaman and Nicobar Islands to appreciate the impact of the tsunami. The islands are located far from the Indian mainland and are part of a chain of islands in the Bay of Bengal. The tsunami affected not only the Andaman and Nicobar Islands but also other regions along the Indian coast, including the states of Tamil Nadu and Kerala.
However, the question specifically asks about a part of the Andaman and Nicobar Islands that was submerged due to the tsunami. Therefore, the correct answer is Indra Point, as it is the only option that correctly identifies a part of the Andaman and Nicobar Islands that was affected by the tsunami.
The other options, Kanyakumari, Tamil Nadu, and Kerala, are incorrect because they are not part of the Andaman and Nicobar Islands. Kanyakumari is a town in Tamil Nadu, while Tamil Nadu and Kerala are states on the Indian mainland. Although these regions were also affected by the tsunami, they are not relevant to the specific question about the Andaman and Nicobar Islands.
Understanding the impact of natural disasters like tsunamis on coastal and island regions is crucial for comprehending the geographical changes that can occur. The 2004 tsunami serves as a significant example of how natural disasters can alter landscapes and affect the lives of people living in these regions.
