Which one of the following is the youngest mountain range of India?

  1. A.Himadri Range
  2. B.Aravalli Range
  3. C.Western Ghat
  4. D.Vindhya Range

Correct answer

A. Himadri Range

Explanation

The correct answer is A, Himadri Range. The Himadri, or Greater Himalaya, is part of the Himalayan system, the youngest fold mountains in India, formed as the Indian plate pushed into the Eurasian plate and folded up the sediments of the old Tethys Sea. The uplift began only about 50 million years ago and is still going on, which is why the region has frequent earthquakes. The Himadri is the highest and most continuous range, with an average height of about 6,000 metres and peaks such as Kanchenjunga and Nanda Devi. Within the Himalaya itself, the outer Shiwalik range is the youngest, but it is not among the options. Option B is wrong because the Aravalli is the oldest fold mountain range of India, worn down over hundreds of millions of years. Option C is wrong because the Western Ghats are the raised western edge of the ancient Deccan plateau. Option D is wrong because the Vindhyas are an old range of Peninsular India made of ancient sedimentary rocks. Exam tip: oldest range, Aravalli; youngest, the Himalaya, and within it the Shiwaliks.

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.
