The channel separating the Andaman Island from the Nicobar Islands is known as

The Andaman and Nicobar Islands are a major archipelago in the Bay of Bengal, consisting of hundreds of islands and islets [3]. These islands are geographically divided into two broad categories: the Andaman group in the north and the Nicobar group in the south [3]. The waterbody that separates these two distinct groups is known as the Ten Degree Channel [3]. It is approximately 150 km wide from north to south and is named so because it lies directly on the 10-degree line of latitude, north of the equator [2][t2]. While other passages exist in the region, such as the Duncan Passage (separating South Andaman from Little Andaman) and the Coco Channel (separating the Andaman Islands from Myanmar's Coco Islands), the 10° channel specifically serves as the boundary between the Andaman and Nicobar clusters [t1][t2].
