The Andaman group of islands and the Nicobar group of islands are separated by which one of the following latitudes?

  1. A.8° N latitude
  2. B.10° N latitude
  3. C.12° N latitude
  4. D.13° N latitude

Correct answer

B. 10° N latitude

Explanation

The correct answer is B, 10° N latitude. The Ten Degree Channel, which runs along this latitude, separates the Andaman group from the Nicobar group.

The Ten Degree Channel lies between Little Andaman in the north and Car Nicobar in the south, and it is about 150 km wide. It links the Bay of Bengal with the Andaman Sea. North of it lie the Andaman Islands with Port Blair (now Sri Vijaya Puram), and south of it the Nicobar Islands, ending at Indira Point on Great Nicobar, the southernmost point of India. Further south, the Six Degree Channel separates Great Nicobar from Sumatra in Indonesia.

Option A is wrong because the Eight Degree Channel lies in the Arabian Sea, between Minicoy and the Maldives. Option C is wrong because 12° N passes through the Andaman group itself and marks no channel. Option D is wrong because 13° N also crosses the Andaman Islands and does not divide the two groups.

Exam tip: Ten Degree Channel = Andaman | Nicobar; Eight Degree = Minicoy | Maldives; Nine Degree = Minicoy | Kalpeni.

Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.

  1. A.2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

Which of the following statements related to latitude are true? 1. Rainfall, temperature and vegetation vary with latitude. 2. The difference between the longest day and the shortest day increases with latitude. 3. Indira Point is located approximately at 6°45' N latitude.

  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
