Which one of the following rivers is NOT a tributary of river Cauvery ?

  1. A.Hemavati
  2. B.Arkavati
  3. C.Indravati
  4. D.Amravati

Correct answer

C. Indravati

Explanation

The correct answer is C, Indravati. The Indravati is a tributary of the Godavari, flowing from Odisha through the Bastar region of Chhattisgarh; it has nothing to do with the Cauvery basin.

The Cauvery rises at Talakaveri in the Brahmagiri hills of Kodagu, Karnataka, and flows south-east through Karnataka and Tamil Nadu to the Bay of Bengal. Its main left-bank tributaries in Karnataka are the Hemavati, Shimsha and Arkavati, and its right-bank tributaries include the Kabini, Bhavani, Noyyal and Amaravati. The Indravati rises in the Kalahandi district of Odisha, flows west through Bastar, where it forms the Chitrakote falls, and joins the Godavari on the border of Chhattisgarh, Maharashtra and Telangana.

A is wrong because the Hemavati joins the Cauvery near Krishnarajasagara in Karnataka. B is wrong because the Arkavati joins the Cauvery at Sangama near Kanakapura. D is wrong because the Amaravati rises in the Anamalai hills and joins the Cauvery near Karur in Tamil Nadu.

Exam tip: Indravati, Pranhita, Manjira and Sabari join the Godavari; Hemavati, Kabini, Bhavani and Amaravati join the Cauvery.

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.

  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.

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.
