Q11
The high altitudinal lake called 'Tso Lhamo' serves as the exact physical source for which major north-eastern river system?
Manas
Teesta
Subansiri
Barak
Explanation
The Teesta River originates from the Tso Lhamo lake (also known as Chho Lhamo) in North Sikkim at an elevation exceeding 5,300 meters, carved through alpine glacial fields.
Q12
The structural geographic feature known as the 'Goriganga' or 'Kali River' forms a natural boundary between India and which neighbouring country before entering Uttarakhand?
Bhutan
Nepal
China (Tibet)
Bangladesh
Explanation
The Kali River (also known as Sharda or Mahakali) originates in the Himalayas at Kalapani and forms a continuous international boundary between India (Uttarakhand) and Nepal based on historical treaties.
Q13
Which left-bank tributary of the Ganga undergoes severe channel shifting and meander loops, historically earning the moniker 'Sorrow of Bihar' due to recurring destructive floods?
Ghaghara
Kosi
Gandak
Ramganga
Explanation
The Kosi River is notorious for its extremely high sediment load and frequent path shifts. Over the past centuries, it has migrated westwards significantly, triggering massive structural damage across north Bihar during monsoon spikes.
Q14
Which of the following left-bank tributaries of the Brahmaputra river converges near the town of Sadiya alongside the Dihang to permanently establish the primary channel layout?
Teesta and Manas
Dibang and Lohit
Subansiri and Dhansiri
Kopili and Barak
Explanation
The river is officially designated as the Brahmaputra from the confluence of three headwaters near Sadiya: the Dihang (Siang), the Dibang, and the Lohit.
Q15
The Kishanganga hydro-electric project, which has been a point of geopolitical contention between India and Pakistan, is located on a tributary of which major river system?
Chenab
Jhelum
Indus Core
Ravi
Explanation
The Kishanganga River is a major tributary of the Jhelum River (part of the Indus system). In Pakistan, the Kishanganga is known as the Neelum River.
Q16
The Yarlung Tsangpo Grand Canyon, recognized as one of the deepest canyons in the world, is sculpted by which structural river course before it cuts through the Eastern Himalayas?
Indus System
Brahmaputra System
Mekong River Line
Salween Corridor
Explanation
The Yarlung Tsangpo River (Brahmaputra) carves out the magnificent Grand Canyon in Tibet as it sweeps around the Namcha Barwa peak before changing its path southward into India.
Q17
Which of the following physical variables explains why the tributaries of the Ganga system like Gandak and Ghaghara bring down exceptionally massive sediment loads?
They flow through oldest, chemically inactive crystalline basalt shields
They drain young, fragile, and loosely packed Himalayan sedimentary structures
Tectonic stagnation within the Indo-Gangetic structural trough suppresses current velocity
The absolute absence of any vegetative forest cover along their entire delta track
Explanation
These tributaries drain the young, fragile, and loose sedimentary rock structures of the high Himalayas. The steep alpine slopes combined with high monsoon precipitation trigger rapid erosion rates.
Q18
Which of the following geographical features explains why the Indus River does not overflow its banks extensively in its upper course despite carrying enormous water volume?
The river bed is situated on an elevated plateau with infinite water absorption
It flows through deeply entrenched, narrow rocky canyons and gorges
The water freezes instantly due to permanent sub-zero thermal inversions
Sub-surface tectonic plates absorb all surplus water via fault cracks
Explanation
In its upper course, the Indus flows through deep, narrow, and structurally stable structural canyons and gorges in the high Himalayan and Karakoram ranges, which strictly confine the channel flow.
Q19
The proposed 'Kosi-Mechi' river interlinking project inside Bihar is designed to transfer surplus water specifically to address irrigation deficits in which region?
The Dry Rohtas Plain Grid
The Seemanchal and Mahananda Basin Zone
The Kaimur Plateau Foothills
The South Magadh Marginal Belt
Explanation
The Kosi-Mechi link is a major river interlinking project in Bihar designed to transfer surplus water from the Kosi to the Mechi (a tributary of Mahananda) to bring immense irrigation relief to the Seemanchal/Mahananda basin zone.
Q20
Which of the following left-bank tributaries of the Ganga river system has its geographic origin entirely inside the alluvial plains rather than the Himalayan peaks?
Ghaghara
Gomti
Gandak
Kosi
Explanation
The Gomti River is a unique left-bank tributary of the Ganga that originates from Gomat Taal (Fulhar Jheet) near Pilibhit in Uttar Pradesh, entirely within the plains ecosystem.
