Which of the following statements regarding the given rivers is/are correct ? 1. Tsangpo crosses over into India under the name of Dihang. 2. Godavari has the second largest river basin covering about 10 percent of the area of India. 3. Rivers Chambal and Betwa are the important tributaries of river Ganga which join river Ganga directly in Uttar Pradesh. Select the answer using the code given below :

  1. A.1 only
  2. B.1 and 2 only
  3. C.2 and 3 only
  4. D.1,2 and 3

Correct answer

B. 1 and 2 only

Explanation

The correct answer is B, 1 and 2 only. The Tsangpo enters India as the Dihang and the Godavari has the second largest basin, but the Chambal and Betwa join the Yamuna, not the Ganga.

The Brahmaputra rises near Mansarovar as the Tsangpo, turns south around Namcha Barwa and enters Arunachal Pradesh as the Siang or Dihang; after the Dibang and Lohit join it, it is called the Brahmaputra. The Godavari, the largest peninsular river, drains about 10 percent of India, second only to the Ganga basin. The Chambal joins the Yamuna in Etawah district, and the Betwa joins it near Hamirpur; the Yamuna then meets the Ganga at Prayagraj.

A is wrong because statement 2 is also correct. C is wrong because statement 3 is false. D is wrong because the Chambal and Betwa are tributaries of the Yamuna and do not join the Ganga directly.

Exam tip: Tsangpo, Dihang, Brahmaputra, Jamuna in Bangladesh; Chambal, Sind, Betwa and Ken all go into the Yamuna.

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.
