Consider the following rivers :
- 1.Brahmani
- 2.Nagavali
- 3.Subarnarekha
- 4.Vamsadhara
Which of the above rise from the Eastern Ghats?
Show answer
Answer: B. The Nagavali and Vamsadhara rise in the Eastern Ghats in Odisha and flow into Andhra Pradesh. The Brahmani forms from the Koel and Sankh on the Chota Nagpur plateau, and the Subarnarekha rises near Ranchi, also on that plateau. So 2 and 4.
Watch for: All four are east-flowing rivers of the same region; check where each one starts.
Why the other options are wrong
- A. Wrong because the Brahmani rises on the Chota Nagpur plateau.
- C. Wrong because the Subarnarekha rises near Ranchi on the Chota Nagpur plateau.
- D. Wrong because both rise on the Chota Nagpur plateau.
