Show answer
Answer: (C) Sutlej
The correct answer is Sutlej.
Key Points
- Statement 1 is correct. The Sutlej is a classic antecedent drainage river. It is older than the Himalayan orogeny (mountain building), so it kept its old course and cut a deep gorge through the mountains at Shipki La.
- Statement 2 is correct. It is an international river flowing through three countries: China (it starts in the Tibet region), India (through Himachal Pradesh and Punjab), and Pakistan (where it joins the Indus system).
- Statement 3 is correct. It rises from Lake Rakshastal on the Tibetan Plateau and is vital for irrigation. It feeds the Indira Gandhi Canal and the Bhakra-Nangal multipurpose project.
- Statement 4 is correct. The main Indus and the Brahmaputra build large deltas with many distributaries before meeting the sea. The Sutlej instead behaves as a major tributary — it joins the Beas, then the Chenab, to form the Panjnad.
Additional Information
- Brahmaputra: Called the Yarlung Tsangpo in Tibet. It flows through China, India and Bangladesh. It forms the Ganges-Brahmaputra Delta, marked by a complex web of distributaries such as the Jamuna.
- Indus: Rises near Lake Mansarovar and flows through China, India and Pakistan. Before entering the Arabian Sea it splits into many distributaries, creating a huge delta south of Karachi.
- Teesta: Rises from Tso Lhamo Lake in Sikkim and flows through only two countries — India and Bangladesh. It is a major tributary of the Brahmaputra and does not rise from the main Tibetan Plateau like the Trans-Himalayan rivers.
The Sutlej is one of only three major antecedent rivers in India that predate Himalayan mountain formation and cut through the ranges, making it crucial for understanding drainage evolution.
Trans-Himalayan rivers like Sutlej behave differently from Himalayan rivers - they don't form distributaries but merge as tributaries into larger systems, reflecting their geological origin and flow patterns.
Antecedent Drainage Systems
Geography antecedent drainage system
Antecedent Drainage: Rivers Older Than Mountains
Antecedent rivers existed before mountain formation and cut through rising ranges
Sutlej is the classic example - older than Himalayan orogeny
These rivers maintain their original course by cutting gorges through mountains
Contrast with consequent rivers that follow the slope of new landforms
Antecedent drainage occurs when a river system predates the geological uplift that creates mountains. As the land slowly rises, the river cuts downward at the same rate, maintaining its original path through the emerging mountain range.
Drainage Types Comparison
Type | Formation | Relationship to Relief | Indian Example |
|---|---|---|---|
Antecedent | River older than mountains | Cuts through rising ranges via gorges | Sutlej at Shipki La |
Consequent | Follows slope of new landforms | Flows down the natural gradient | Most Peninsular rivers |
Superimposed | Cuts down from higher rock layer | Ignores underlying rock structure | Some Himalayan tributaries |
Sutlej as Antecedent River
Shipki La gorge - where Sutlej cuts through the main Himalayan range
River maintained its Tibet-to-plains course during Himalayan uplift
Deep valley cutting demonstrates the river's erosive power over geological time
Trap: All Trans-Himalayan rivers are antecedent - False. Indus and Brahmaputra are also antecedent, but not all rivers from Tibet show this pattern
Confusion: Antecedent vs Consequent - remember ante means 'before', so antecedent rivers came before the mountains
Sutlej River System
Geography Sutlej
Sutlej: The Shatadru of Ancient Times
Originates from Lake Rakshastal on Tibetan Plateau near Mount Kailash
Flows through China, India, Pakistan - three countries total
Joins Beas then Chenab to form Panjnad - no separate distributaries
Feeds Bhakra-Nangal project and Indira Gandhi Canal

Trap: Sutlej forms distributaries like other major rivers - False. It joins other rivers as tributary, doesn't split into distributaries
Confusion: Lake Mansarovar vs Lake Rakshastal - Sutlej rises from Rakshastal, Indus from near Mansarovar
Trans-Himalayan Rivers Comparison
Geography Brahmaputra Indus Teesta
Major Rivers from Tibetan Plateau: Key Distinctions
Indus, Brahmaputra, Sutlej - the three major Trans-Himalayan rivers
All originate in Tibet and show antecedent drainage patterns
Indus and Brahmaputra form large deltas with distributaries
Teesta originates in Sikkim, not main Tibetan Plateau
Trans-Himalayan Rivers Comparison
River | Origin | Countries | Delta/Distributaries | Key Feature |
|---|---|---|---|---|
Indus | Near Lake Mansarovar | China, India, Pakistan | Large delta south of Karachi | Longest river in Pakistan |
Brahmaputra | Chemayungdung glacier | China, India, Bangladesh | Ganges-Brahmaputra Delta | Called Yarlung Tsangpo in Tibet |
Sutlej | Lake Rakshastal | China, India, Pakistan | No distributaries - joins as tributary | Antecedent gorge at Shipki La |
Teesta | Tso Lhamo Lake, Sikkim | India, Bangladesh | No major delta | Not from main Tibetan Plateau |
Distributary Patterns
Indus Delta - splits into multiple channels before Arabian Sea
Brahmaputra - forms complex distributary network as Jamuna in Bangladesh
Sutlej uniqueness - behaves as tributary, joins Panjnad system instead of forming own delta
Trap: All rivers from Tibet flow through three countries - False. Teesta flows through only India and Bangladesh
Trap: Teesta is Trans-Himalayan - Misleading. It originates in Sikkim Himalayas, not main Tibetan Plateau
Key Distinction: Only Sutlej among major rivers does NOT form distributaries
River Distributaries vs Tributaries
Geography distributaries
Distributaries vs Tributaries: Critical River Concepts
Distributaries split from main river, tributaries join the main river
Distributaries form in lower course near sea, tributaries in upper/middle course
Sutlej acts as tributary (joins Panjnad), unlike Indus/Brahmaputra that form distributaries
Distributaries vs Tributaries
Aspect | Distributaries | Tributaries |
|---|---|---|
Direction | Flow away from main river | Flow into main river |
Location | Lower course, near delta | Upper/middle course, confluence points |
Formation | River splits due to sediment | Smaller rivers join larger ones |
Examples | Ganga distributaries in Sundarbans | Yamuna joins Ganga at Allahabad |
Indian Examples
Ganga distributaries - Hooghly, Padma branches in Bengal delta
Indus distributaries - multiple channels in Sindh delta, Pakistan
Panjnad system - five rivers (including Sutlej) converge as tributaries

Memory Aid: Distributaries Divide (split away), Tributaries Together (join)
Question Context: Sutlej doesn't form distributaries - this eliminates rivers that split into deltas
