Question map
Gandikota canyon of South India was created by which one of the following rivers ?
Explanation
The correct answer is Option 3: Pennar.
The Gandikota canyon, famously known as the Grand Canyon of India, is located in the Kadapa district of Andhra Pradesh. It was formed by the Pennar River cutting through the Erramala hills of the Eastern Ghats over centuries. This natural gorge is characterized by massive, tiered formations of red sandstone, which the river has sculpted into a deep valley.
- Pennar (Option 3): It is the primary river responsible for the erosion and geological formation of this specific canyon near the Gandikota Fort.
- Cauvery (Option 1): Flows further south through Karnataka and Tamil Nadu, forming waterfalls like Shivanasamudra but not the Gandikota canyon.
- Manjira (Option 2): A tributary of the Godavari, it flows primarily through Maharashtra, Karnataka, and Telangana.
- Tungabhadra (Option 4): A major tributary of the Krishna River, known for its rocky terrain in Hampi, but it does not traverse the Gandikota region.
PROVENANCE & STUDY PATTERN
Full viewThis question is a classic 'Book + News' hybrid. While Majid Husain (p.21) explicitly states the Pennar flows through a 'gorge of Cuddapah quartzite', the specific name 'Gandikota' became famous via tourism news ('Grand Canyon of India'). It rewards mapping physical features over rote memorization of tributaries.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: Did the Cauvery River form the Gandikota canyon of South India?
- Statement 2: Did the Manjira River form the Gandikota canyon of South India?
- Statement 3: Did the Pennar (Penna) River form the Gandikota canyon of South India?
- Statement 4: Did the Tungabhadra River form the Gandikota canyon of South India?
- Directly names the river responsible for carving Gandikota as the Penna River.
- States that the Penna River 'carved' the canyon through ancient rock formations, which attributes canyon formation to Penna rather than Cauvery.
- Explicitly says the 'river Pennar cuts through the Erramala hills, forming a gorge' called the Grand Canyon of India.
- Identifies the Pennar (Penna) as the agent forming the gorge at Gandikota, contradicting attribution to the Cauvery.
- States that 'Over time, the Pennar River carved the pink granite rock of Erramala Hills and formed Gandikota Canyon.'
- Provides a clear, journalistic attribution of the canyon's formation to the Pennar River rather than the Cauvery.
Describes the Kaveri (Cauvery) as rising on the Mysore Plateau as a rocky mountain stream forming rapids, cataracts and waterfalls.
A student could use this to infer that the Cauvery has the energetic flow and bedrock erosive potential to carve deep features and then check maps to see if its course passes Gandikota.
States that Cauvery is a consequent peninsular river descending from the Western Ghats and flowing east to the Bay of Bengal (i.e., its general direction and origin).
Combine with a map to verify whether the river’s downstream path goes through the Gandikota area where a canyon might be located.
Gives an example (Narmada) of a river forming a picturesque gorge in hard rock while flowing in a rift valley, showing rivers can form prominent gorges under suitable structural/geologic settings.
A student could compare the geologic/structural setting of Gandikota (rift valley vs plateau river) to see if the Narmada-like mechanism applies to the Cauvery there.
Notes that rivers on steep slopes (western Ghats) carve narrow valleys with steep gradients, cataracts and waterfalls—demonstrating the general ability of peninsular rivers to incise bedrock.
Use this pattern plus local topography around Gandikota to judge whether incision by Cauvery could plausibly create a canyon at that location.
- Explicitly says which river carved the canyon: identifies the Penna River as the agent that carved Gandikota Canyon.
- Directly attributes the gorge formation to the Penna River, which contradicts the claim that the Manjira River formed it.
- States that the river Pennar cuts through the Erramala hills, forming the gorge known as the Grand Canyon of India.
- Names Pennar/Penna (not Manjira) as the river responsible for forming the Gandikota gorge.
- Describes how the Pennar River carved the Erramala Hills to form Gandikota Canyon.
- Reinforces that Pennar/Penna, rather than the Manjira River, formed the canyon.
Identifies the Manjira as an important right‑bank tributary of the Godavari, establishing which larger river system Manjira belongs to.
A student can check maps to see whether the Manjira’s course and watershed are spatially located at/near Gandikota (i.e., whether the Manjira flows through that canyon area) or lie elsewhere in the Godavari basin.
Notes the Manjra/Manjira as a principal tributary of the Godavari and that the Godavari forms a picturesque gorge in its lower reaches, providing an example that peninsular rivers/tributaries can create gorges.
Compare the geographic location of the Godavari gorge mentioned with Gandikota on a map to see if they are the same feature or if Gandikota is formed by a different river.
Explains the geomorphic rule that rivers that are antecedent to mountain uplift can carve deep gorges across ranges — a general mechanism by which canyons/gorges form.
Use geological/topographic maps of the Gandikota area to test whether the canyon has features of an antecedent gorge and whether the Manjira’s course could produce such a gorge given local relief and rock structure.
States the broad pattern that most major peninsular rivers flow east from the Western Ghats and drain into the Bay of Bengal, framing expectations of river directions in South India.
A student can use this rule plus a map to see if Manjira’s flow direction and location match Gandikota’s east‑flowing canyon location or whether another east‑flowing river (e.g., the Penna/Krishna/Godavari) is a better candidate.
Points out that many large peninsular rivers originate in the Western Ghats and drain eastwards — a reminder to check river sources and courses when attributing canyon formation.
Verify which river actually passes Gandikota by checking the origin and course of regional rivers against the canyon’s coordinates to eliminate or support Manjira as the canyon‑forming river.
- Explicitly states the Pennar River carved the Erramala Hills and formed Gandikota Canyon.
- Direct, high-quality news source wording linking the river to the canyon's formation.
- Says the Gandikota Canyon is carved by the Penna River.
- Specifies the river created a dramatic gorge through ancient rock formations at Gandikota.
- States the river Pennar cuts through the Erramala hills, forming a gorge identified as Gandikota.
- Connects the river's cutting action directly to the gorge formation tourists call the Grand Canyon of India.
States the Pennar rises in Kolar (South Mysore Plateau) and 'flows through a gorge of Cuddapah quartzite', linking Pennar to gorge/canyon-forming rock and terrain.
A student could check a map/atlas or local place names to see whether Gandikota lies on the Pennar's gorge in the Cuddapah (Kadapa) quartzite belt.
Lists Pennar among major peninsular river basins, confirming it is a distinct river system in southern India that could carve significant landforms.
Compare the Pennar basin extent on a river-basin map with the location of Gandikota to assess whether the canyon falls inside the Pennar basin.
Gives the general pattern that many peninsular rivers in South India flow eastwards to the Bay of Bengal, providing expected direction of Pennar's course.
Use the eastward flow rule with a map to follow the Pennar's downstream path from its source toward the Bay of Bengal and see if it passes Gandikota.
Notes that large rivers on the Peninsular plateau have origins in the Western Ghats and flow east; it's relevant as contextual geography of southern rivers including smaller systems like Pennar.
Place Pennar within this peninsular drainage framework on a map to judge if its course and source-region make it a plausible agent for carving Gandikota canyon.
Describes the Deccan/peninsular plateau and regional slopes that determine river flow directions and where rivers carve valleys or gorges.
Combine this plateau slope information with a topographic map around Gandikota to determine if Pennar's gradient and setting are sufficient to form a canyon there.
- Explicitly states which river carved Gandikota canyon: names the Penna River as the agent of carving.
- Says the Penna River 'carved' a dramatic gorge through the local rock, attributing canyon formation to Penna.
- Directly describes the Pennar River as the force that carved the rock and formed Gandikota Canyon.
- Uses active phrasing ('carved ... and formed') tying canyon origin to the Pennar River.
- Identifies the 'mighty Penna River' as having carved a spectacular gorge at Gandikota.
- Places the Penna River as the creator of one of South India's most dramatic landscapes, again attributing canyon formation to Penna.
States that the Tungabhadra is an important tributary of the Krishna and that the Krishna flows through gorges (e.g., in Srisailam Hills), showing peninsular rivers and their tributaries can carve gorges.
A student could locate Gandikota and trace whether Tungabhadra (as a Krishna tributary) flows at that location on a map to see if it could have formed the canyon.
Lists the Tungabhadra explicitly among the Krishna's tributaries, confirming the river's regional identity and relevance to South Indian canyon-forming drainage.
Use a regional map to follow the Tungabhadra's course relative to Gandikota to assess plausibility.
Gives an example (Narmada) of a peninsular river forming a 'picturesque gorge' in hard rock, demonstrating that rivers in peninsular India do form canyons/gorges.
Apply the general rule that rivers can cut gorges in resistant rock to evaluate whether Tungabhadra could similarly have formed Gandikota, using local geology/maps.
Explains that major peninsular rivers originate in the Western Ghats and flow east, implying regional drainage patterns that control where gorges/canyons may form.
Compare the origin and eastward course pattern with the Tungabhadra's course on a map to judge if its trajectory passes Gandikota.
Contains a multiple-choice context listing Tungabhadra among rivers in a question about rivers flowing through a rift valley, indicating educational association of rivers with valley/gorge formation (though not asserting Tungabhadra does so).
Use caution: check geological maps to verify whether Gandikota is a rift-related gorge and whether Tungabhadra occupies such a valley.
- [THE VERDICT]: Sitter for the observant, Trap for the pure book-worm. Source: Majid Husain (Geography of India) p.21 + The Hindu (Tourism features).
- [THE CONCEPTUAL TRIGGER]: Drainage Systems > Peninsular Rivers > Unique Geomorphological Features (Gorges, Waterfalls, River Islands).
- [THE HORIZONTAL EXPANSION]: Map these river signatures: 1. Narmada (Marble Rocks/Dhuandhar), 2. Cauvery (Hogenakkal & Shivasamudram), 3. Chambal (Ravines/Badlands), 4. Brahmaputra (Majuli), 5. Pennar Tributaries (Papaghni, Chitravati).
- [THE STRATEGIC METACOGNITION]: Don't just memorize 'Origin' and 'Mouth'. If a standard book mentions a river forms a 'gorge' or 'waterfall', immediately Google its specific name. If that place has a nickname (e.g., 'Grand Canyon of India'), it is a potential question.
Cauvery rises from the southern Mysore Plateau/Western Ghats, so knowledge of the Ghats explains origins and early river behaviour.
High-yield for drainage questions: explains origin, slope direction, and seasonal runoff of major South Indian rivers; links to climate (monsoon distribution) and physiography questions; enables elimination of wrong options about river sources and basin characteristics.

Belum Caves. Located in the same geological belt (Kurnool/Kadapa), these are the second-longest caves in the Indian subcontinent, formed by the action of underground water on limestone/quartzite. Often visited with Gandikota.
The 'Regional Dominance' Hack. Gandikota is in the Kadapa district (Rayalaseema region). Cauvery is too far south (TN/Karnataka). Manjira is a Godavari tributary (Telangana/Maharashtra). Tungabhadra is a Krishna tributary (Western Andhra/Karnataka). The Pennar is the primary river defining the Rayalaseema/Kadapa landscape. Geography dictates the answer.
History & Culture Link: Gandikota Fort, sitting on this gorge, was the stronghold of the **Pemmasani Nayakas**, who were commanders under the Vijayanagara Empire. This connects Physical Geography to Medieval History.
