Q240. Which major river traverses the Rajasthan desert?
[SSC GD Constable (7 May 2026, Shift 3)]
(A) Chambal
(B) Banas
(C) Luni
(D) Sabarmati
Answer: (C) Luni
Explanation: The Luni emerges from the Aravalli region near Ajmer and runs through arid western Rajasthan towards the Rann of Kutch, where its flow dissipates inland. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
Q239. Name India’s highest dam from these choices.
[SSC GD Constable (8 May 2026, Shift 2)]
(A) Bhakra Nangal
(B) Hirakud Dam
(C) Tehri Dam
(D) Sardar Sarovar
Answer: (C) Tehri Dam
Explanation: Tehri is a tall earth-and-rockfill dam on the Bhagirathi River in Uttarakhand. It supplies hydropower and water and forms the Tehri reservoir. Reservoir location, river discharge and terrain affect the supply of water for irrigation and electricity.
Q238. Bada Imambara in Lucknow stands near which river?
[SSC MTS 2025 Paper (9 February 2026, Shift 2)]
(A) Ganga
(B) Yamuna
(C) Gomti
(D) Kaveri
Answer: (C) Gomti
Explanation: The Gomti flows through Lucknow in Uttar Pradesh and is a left-bank tributary of the Ganga. The historical Bara Imambara complex is close to its bank. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
Q237. Which river does not belong to the Ganga tributary system?
[SSC MTS 2025 Paper (9 February 2026, Shift 3)]
(A) Ghaghara
(B) Kosi
(C) Mahadayi
(D) Gandak
Answer: (C) Mahadayi
Explanation: Mahadayi, also called Mandovi, drains westwards through Goa to the Arabian Sea. Ghaghara, Kosi and Gandak all contribute to the Ganga system. The wider drainage network links Himalayan tributaries with major alluvial floodplains and downstream deltas.
Q236. What is the length of National Waterway 2 on the Brahmaputra?
[SSC MTS 2025 Paper (9 February 2026, Shift 3)]
(A) 451 km
(B) 891 km
(C) 1108 km
(D) 1720 km
Answer: (B) 891 km
Explanation: National Waterway 2 covers the Brahmaputra stretch between Sadiya and Dhubri in Assam. This river route supports inland transport in northeastern India. Himalayan sediment, seasonal floodwater and heavy rainfall strongly shape the river channels and adjoining plains.
Q235. In which Indian state is Sambhar Lake?
[SSC MTS 2025 Paper (10 February 2026, Shift 1)]
(A) Rajasthan
(B) Punjab
(C) Gujarat
(D) Haryana
Answer: (A) Rajasthan
Explanation: Sambhar is a saline inland lake in Rajasthan, west of Jaipur. Its closed basin is fed by seasonal streams and is especially important for salt production. The balance of rainfall, inflowing streams, evaporation and coastal connections determines the waterbody’s character.
Q234. Which river is called the Dakshin Ganga?
[SSC MTS 2025 Paper (11 February 2026, Shift 3)]
(A) Narmada
(B) Godavari
(C) Brahmaputra
(D) Brahmani
Answer: (B) Godavari
Explanation: The Godavari rises near Nashik in Maharashtra and is the major river system of peninsular India. It flows eastwards through the Deccan and debouches into the Bay of Bengal. The wider drainage network links Himalayan tributaries with major alluvial floodplains and downstream deltas.
Q233. Between which ranges does the Narmada flow?
[MP Police SI (16 January 2026, Shift 1)]
(A) Western Ghats and Eastern Ghats
(B) Satpura and Vindhya
(C) Aravalli and Vindhya
(D) Himalayas and Aravalli
Answer: (B) Satpura and Vindhya
Explanation: The Narmada follows a structural rift with the Vindhya hills on the north and the Satpura system on the south. It drains westward. Plateau slopes and underlying geological structures are especially important in determining peninsular drainage patterns.
Q232. Which description correctly defines a tributary?
[RRB NTPC Graduate CBT-I (22 March 2026, Shift 3)]
(A) A branch flowing away from a river
(B) A river joining a larger river
(C) A lake at a river mouth
(D) Saline water mixed with river water
Answer: (B) A river joining a larger river
Explanation: A tributary delivers water into a parent river. A distributary, by contrast, branches away from a main channel, especially within a river delta. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
Q231. Which river pair is an exception to the usual eastward drainage of major peninsular rivers?
[RRB NTPC Graduate CBT-I (24 March 2026, Shift 3)]
(A) Godavari and Krishna
(B) Kaveri and Krishna
(C) Mahanadi and Kaveri
(D) Narmada and Tapi
Answer: (D) Narmada and Tapi
Explanation: Most large peninsular rivers flow towards the Bay of Bengal. Narmada and Tapi flow west through fault-controlled troughs before reaching the Arabian Sea. Plateau slopes and underlying geological structures are especially important in determining peninsular drainage patterns.
