Which channel separates the Andaman Islands from the Nicobar Islands?

The Ten Degree Channel separates the Andaman Islands from the Nicobar Islands in the Bay of Bengal.

The channel is named for its position near 10 degrees north latitude. It runs roughly east–west and is about 150 kilometres wide from north to south, while its east–west length is approximately 10 kilometres. Its minimum depth is about 7.3 metres, making it a significant geographic division within the island territory.

The Andaman and Nicobar Islands are administered together as an Indian Union Territory, but the two island groups are distinct. The Ten Degree Channel is commonly confused with the Nine Degree Channel, which lies farther west near Lakshadweep and separates Minicoy from the main Lakshadweep group. Duncan Passage is another nearby waterway, but it separates islands within the Andaman group rather than dividing the Andamans from the Nicobars.
