Which of the following pairs is NOT correctly matched? (1) Kosi – Consequent river (2) Narmada – Rift valley river (3) Sutlej – Antecedent river (4) Ghaggar – Endoreic river
Options
Answer: (1) Kosi – Consequent river
Explanation:
Kosi is not a consequent river but an antecedent river — it originated before the rise of the Himalayas and has maintained its course by cutting through the rising mountains. Narmada is correctly a rift valley river flowing through a graben (rift valley). Sutlej is correctly an antecedent river originating in Tibet and cutting through the Himalayas. Ghaggar is an endoreic (inland drainage) river that disappears into the Thar Desert. Hence the incorrectly matched pair is Kosi–Consequent river.
