The Andaman group of islands and the Nicobar group of islands are separated by which one of the following latitudes?
10° N latitude
Geographical Separation of Andaman and Nicobar Islands by Latitude
The question asks about the specific latitude that separates the Andaman group of islands from the Nicobar group of islands.
These two distinct island groups are part of the Andaman and Nicobar Islands Union Territory of India, located in the Bay of Bengal. While they are administered together, they are geographically separated by a significant water body.
This body of water is commonly known as a channel. The specific latitude line that passes through this channel and effectively separates the northern Andaman group from the southern Nicobar group is a key geographical marker.
Identifying the Separating Latitude
Let's consider the options provided:
- 8\degree N latitude
- 10\degree N latitude
- 12\degree N latitude
- 13\degree N latitude
Geographical surveys and maps confirm that the channel separating these two island groups is located around the 10\degree North latitude line. This channel is often referred to as the Ten Degree Channel.
The Ten Degree Channel is about 150 km wide. To the north of this channel are the islands of the Andaman group, with the Little Andaman Island being the southernmost major island. To the south of this channel are the islands of the Nicobar group, with Car Nicobar Island being the northernmost major island.
Therefore, the latitude that separates the Andaman group of islands and the Nicobar group of islands is 10\degree N latitude.
| Geographical Feature | Separating Latitude |
|---|---|
| Andaman Group of Islands | 10\degree N Latitude (Ten Degree Channel) |
| Nicobar Group of Islands |
Understanding the geographical location of these islands and the prominent channels or latitudes that divide them is important for studying the physical geography of India.

| Feature | Description | Key Separations |
|---|---|---|
| Location | Bay of Bengal | |
| Groups | Andaman Islands (North), Nicobar Islands (South) | |
| Separation | Ten Degree Channel | 10\degree N Latitude |
| Duncans Passage | Separates Great Andaman from Little Andaman | |
| Great Channel | Separates Great Nicobar from Sumatra (Indonesia) |
Additional Information: Latitudes and Channels
Latitudes are imaginary horizontal lines that circle the Earth, parallel to the Equator. They measure the distance north or south of the Equator (0\degree latitude). North latitudes are those in the Northern Hemisphere, and South latitudes are in the Southern Hemisphere.
Channels in geography often refer to a wide strait or waterway between two landmasses that links two seas or lakes.
- The Ten Degree Channel is a significant channel because it marks a clear geographical and administrative boundary between the Andaman and Nicobar groups.
- Other important channels or straits around India include the Eight Degree Channel (separating Minicoy from the Maldives) and the Nine Degree Channel (separating Minicoy from the main Lakshadweep archipelago).
Knowing these key separating latitudes and channels helps in mapping and understanding the island territories of India.
