Ten Degree Channel

Understanding Water Bodies Separating Islands

The question asks about the specific water body that acts as a geographical separator between the Andaman Islands and the Nicobar Islands. These island groups are part of India, located in the Bay of Bengal.

Identifying the Separating Water Body

Different water bodies separate various landmasses and islands around the world. To answer this question, we need to know which channel or strait lies between the Andaman group in the north and the Nicobar group in the south.

Let's examine the options provided:

  • Gulf of Mannar
  • Ten Degree Channel
  • Eleven Degree Channel
  • Palk Strait

Key Water Body: Ten Degree Channel

The Ten Degree Channel is a strait located in the Bay of Bengal. It is about 150 km wide and separates the Little Andaman Island (which is part of the Andaman Islands group) from Car Nicobar Island (which is part of the Nicobar Islands group). The channel is named because it lies on the 10-degree line of latitude North. This geographical position makes it the distinct water body that separates these two island chains.

Analyzing Other Options

Let's look at why the other options are not correct:

  • Gulf of Mannar: This gulf is located between the southeastern tip of India and the west coast of Sri Lanka. It is geographically far from the Andaman and Nicobar Islands and does not separate them.
  • Eleven Degree Channel: This channel is part of the Lakshadweep archipelago, located off the southwestern coast of India. It lies between Ameni Island and Cannanore Island (or between Ameni and the northern islands of Lakshadweep). It is not located near the Andaman and Nicobar Islands.
  • Palk Strait: This strait separates the state of Tamil Nadu in India and the Jaffna District of the Northern Province of Sri Lanka. Like the Gulf of Mannar, it is located between India and Sri Lanka and does not separate the Andaman and Nicobar Islands.

Based on the geographical locations, the Ten Degree Channel is the correct water body that separates the Andaman and Nicobar Islands.

Important Channels and Straits in the Region
Water Body Separates Location
Ten Degree Channel Andaman Islands and Nicobar Islands Bay of Bengal
Gulf of Mannar India (Tamil Nadu) and Sri Lanka Indian Ocean
Eleven Degree Channel Ameni Island and Cannanore Island (Lakshadweep) Arabian Sea
Palk Strait India (Tamil Nadu) and Sri Lanka Bay of Bengal / Indian Ocean
Duncan Passage South Andaman and Little Andaman Bay of Bengal
Great Channel Great Nicobar and Sumatra (Indonesia) Indian Ocean

Therefore, the water body separating Andaman and the Nicobar Islands is the Ten Degree Channel.

Revision Table: Channels and Straits

It is important to remember key channels and straits and what landmasses they separate for geography exams.

  • Ten Degree Channel: Andaman and Nicobar
  • Palk Strait: India and Sri Lanka
  • Gulf of Mannar: India and Sri Lanka
  • Duncan Passage: South Andaman and Little Andaman
  • Great Channel: Great Nicobar and Sumatra
  • Eight Degree Channel: Minicoy (Lakshadweep) and Maldives
  • Nine Degree Channel: Minicoy (Lakshadweep) and main Lakshadweep group

Additional Information: Andaman and Nicobar Islands

The Andaman and Nicobar Islands are a group of islands at the juncture of the Bay of Bengal and the Andaman Sea. They form a Union Territory of India. The islands are home to several indigenous tribes. Port Blair is the capital of the Union Territory, located on South Andaman Island. The highest point is Saddle Peak, located in North Andaman Island.
