Gandikota canyon of South India was created by which one of the following rivers ?
Show answer
Answer: C. Gandikota canyon in Kadapa district of Andhra Pradesh was carved by the Pennar (Penna) river cutting through the Erramala hills. It is often called the 'Grand Canyon of India'.
Watch for: Students guess bigger rivers like Cauvery or Tungabhadra instead of the Pennar.
Why the other options are wrong
- A. Wrong because the Cauvery flows through Karnataka and Tamil Nadu, not Gandikota.
- B. Wrong because the Manjira is a Godavari tributary in Telangana and Karnataka.
- D. Wrong because the Tungabhadra flows past Hampi, not through Gandikota.
