1. The Brahmaputra, Irrawaddy, and Mekong Rivers originate in Tibet and flow in parallel mountain ranges in their upper reaches. Of these rivers, Brahmaputra makes a “U” turn in its course to flow into India. This “U” turn is due to?
(a) Uplift of folded Himalayan ranges.
(b) Syntaxial bending of geologically young Himalayas.
(c) Geo-tectonic disturbance in the tertiary folded mountain chains.
(d) Both (a) and (b) above.
[I.A.S. (Pre) 2011]
Ans. (b) Syntaxial bending of geologically young Himalayas.
- The Himalayan mountains on the western and eastern sides bend sharply south in a sharp, bent shape.
- This bend is called a syntaxial bend.
- On the eastern side of Arunachal Pradesh, the mountain changes direction quickly from east to south, almost like a hairpin bend.

- The Lohit river begins in eastern Tibet and travels 200 kilometres before reaching the Assam plains.
- This river is also a tributary of the Brahmaputra river.

(c) India, Pakistan, Bangladesh, Sikkim
(d) Bangladesh, West Bengal, Bhutan, Nepal.
[U.P.P.C.S. (Pre) 1990]
Ans. (a) Tibet, Bangladesh, India

8. Which of the following is/are tributary/tributaries of Brahmaputra?
1. Dibang
2. Kameng
3. Lohit
Select the correct answer using the code given below :
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
[I.A.S. (Pre) 2016]
Ans. (d) 1, 2 and 3
- The Brahmaputra river is fed by several rivers, such as the Kameng, Sankosh, Raidak, Amochu, Dibang, Lohit, and Burhi dihing.
- The Dibang river runs through the Dibang Valley in Arunachal Pradesh and the Kameng and Lohit rivers both originate in Tibet before flowing through Arunachal Pradesh.

9. Which of the following rivers have almost the same point of the beginning?
(a) Brahmaputra and Ganga
(b) Tapi and Beas
(c) Brahmaputra and Indus
(d) Indus and Ganga
[U.P.P.C.S. (Pre) 2006]
Ans. (c) Brahmaputra and Indus
- The Qinghai Tibetan Plateau, commonly known as the Tibetan Plateau, is an area of incredibly high elevation, averaging more than 4,500 meters, and thus known as the “Roof of the World”.
- Covering 2.5 million sq. km., it is the source for some of the world’s largest rivers, such as the Yangtze, Huang He (Yellow River), Mekong, Indus, Satluj, Brahmaputra, and Irrawaddy.
- Therefore, it is obvious that the Brahmaputra and Indus rivers start from the Tibetan Plateau.

10. Given below are two statements, one is labelled as Assertion (A) and other as Reason (R) :
Assertion (A): Teesta river was earlier a tributary of Ganga, now it is a tributary of Brahmaputra.
Reason (R): River capturing is a major feature of Himalayan rivers.
Select the correct answer using the codes given below.
Codes :
(a) Both (A) and (R) are true and (R) is correct explanation of (A)
(b) Both (A) and (R) are true, but (R) is not correct explanation of (A).
(c) (A) is true, but (R) is false.
(d) (A) is false, but (R) is true.
[U.P.P.C.S. (Pre) 2021]
Ans. (a) Both (A) and (R) are true and (R) is correct explanation of (A)
- Approximately 300 years ago, the Teesta River flowed into the Ganga River, but now it flows into the Brahmaputra River.
- This is a natural process called river capture, which is more common during the early stages of valley development because the streams are actively eroding and making the valley longer.
- River capture can also happen later on in the valley’s life when the river erodes the sides and intersects with other rivers.
