Nilgiri is one of the oldest mountain ranges, located at the tri-junction of which three states?

  1. A.Northern UP, Uttarakhand, Himachal Pradesh
  2. B.Gujarat, Rajasthan, Haryana
  3. C.Assam, Nagaland, Tripura
  4. D.Tamil Nadu, Kerala, Karnataka

Correct answer

D. Tamil Nadu, Kerala, Karnataka

Explanation

The correct answer is D, Tamil Nadu, Kerala, Karnataka. The Nilgiri Hills, the 'Blue Mountains', rise where the borders of these three states meet, at the junction of the Western and Eastern Ghats. Their highest peak is Doddabetta (2,637 m), near Ooty (Udhagamandalam) in Tamil Nadu. The Nilgiri Biosphere Reserve, set up in 1986, was India's first biosphere reserve and covers parts of all three states. The hills are home to the Toda tribe and the Nilgiri tahr. A is wrong because Uttarakhand and Himachal Pradesh lie in the Himalayas, which are young fold mountains far to the north. B is wrong because the Gujarat-Rajasthan-Haryana belt is the region of the Aravallis, among India's oldest fold mountains, but they are not the Nilgiris. C is wrong because Assam, Nagaland and Tripura are in the north-east, far from these southern hills. Exam tip: the Nilgiris join the Western and Eastern Ghats at the Tamil Nadu-Kerala-Karnataka tri-junction; the highest peak is Doddabetta.

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.
