Explanation: The total sea boundary of India, including the territorial waters of the mainland, Andaman and Nicobar, and Lakshadweep, is a significant geographical fact that is often tested in various competitive examinations. The sea boundary is not just the coastline but includes the territorial waters up to 12 nautical miles from the coast, as per international maritime law.
India's mainland coastline stretches over 7,516.6 km, and when the territorial waters of the Andaman and Nicobar Islands and the Lakshadweep Islands are included, the total sea boundary becomes 7,516 km. This figure is derived from official geographical surveys and is widely accepted in geographical studies and competitive examinations.
The Andaman and Nicobar Islands are a union territory of India located in the Bay of Bengal, and the Lakshadweep Islands are a union territory located in the Arabian Sea. Both these island territories significantly contribute to India's maritime boundary, making the total sea boundary a comprehensive measure of India's maritime presence.
It is important to note that the sea boundary is different from the coastline, which is the length of the mainland's shore. The sea boundary includes the territorial waters, which are an extension of the country's sovereignty over the sea adjacent to its land territory. This concept is crucial in understanding India's maritime jurisdiction and its strategic importance in the Indian Ocean region.
In competitive examinations, it is essential to remember the exact figure of 7,516 km, as slight variations can lead to incorrect answers. The figure is derived from official surveys and is a standard reference in geographical studies. Therefore, students should ensure they have the correct figure memorized and understand the concept of territorial waters to avoid common misconceptions and errors.
