What is the most suitable reason for the development of inland drainage in the Thar region? A Dense glaciers and heavy snow B Very deep sea gulf C Low rainfall sandy terrain and closed basins D Extensive delta on eastern coast
Correct answer: C In arid regions rivers may end before reaching the sea. Exam tip: remember Luni with Thar.

The difference between Bhangar and Khadar is most related to which process of river systems? A Erosion by sea waves B Flow of volcanic lava C Expansion of glacier D Position of older and newer alluvial deposits
Correct answer: D Bhangar is older alluvium and Khadar is newer alluvium. Exam tip: connect both with flood plains and deposition.
View question details Question 7 Expert Level 28
Why does Khadar soil get renewed repeatedly? A Rivers deposit new alluvium during floods B Sea sends tides up to the Himalayas C Glaciers melt in the desert D Rocks instantly turn into lava
Correct answer: A Khadar is newer alluvium of flood plains. Exam tip: remember it as fertile and repeatedly renewed soil.

The vast alluvial plains of northern India were formed by long-term deposition of which combined river systems? A Narmada Tapi and Mahi B Indus Ganga and Brahmaputra C Luni Sabarmati and Periyar D Krishna Kaveri and Vaigai
Correct answer: B Northern plains are formed by deposits of Himalayan river systems. Exam tip: connect plain formation with river deposition.

If a river has steep slope in upper course and gentle slope in lower course, how will river work change? A Only vertical erosion will occur downstream B Deposition upstream and gorges downstream will form C Erosion will dominate upstream and deposition downstream D River work will stop in both parts
Correct answer: C Slope and velocity control river work. Exam tip: understand upper and lower course separately.

Why is a condition like the Ganga plain suitable for meander formation? A Because there are only glaciers there B Because the river flows backward from the sea there C Because no deposition occurs there D Because low slope slows flow and increases lateral erosion and deposition
Correct answer: D In plains rivers slow down and form winding courses. Exam tip: connect meanders with lateral erosion.

Which combination is most favourable for delta formation at a river mouth? A Low velocity high sediment and shallow calm coastal area B Steep mountain slope and sediment-free water C Closed desert basin and low rainfall D River origin from the sea
Correct answer: A A delta forms by deposition when river velocity decreases. Exam tip: connect deposition with delta.

How can the main difference between an estuary and a delta be understood? A In an estuary river never meets the sea B Delta has branched deposition while estuary has an open deep mouth C Both form only on mountains D Both have no relation with rivers
Correct answer: B Delta is linked with deposition and estuary with tidal open mouth. Exam tip: remember eastern and western coast difference.

Why is the presence of the Indus river system in India called limited but important? A Because it flows only in South India B Because it is a distributary of Ganga C Because a large part lies in Pakistan but its major tributaries are linked with north-western India D Because it forms the largest delta in the Bay of Bengal
Correct answer: C The Indus system is linked with both India and Pakistan. Exam tip: remember its tributaries and regional position.

Understanding the relation between Yamuna and Chambal clarifies which indirect link in the Ganga system? A Chambal is a distributary of Brahmaputra B Chambal is a western branch of Luni C Chambal is the estuary of Narmada D Chambal is a tributary of Yamuna and Yamuna is part of the Ganga system
Correct answer: D Chambal is linked with the Ganga system through Yamuna, not directly. Exam tip: understand indirect river links.

What is the correct way to identify the Son river in the Ganga system? A Understanding it as a southern tributary of the Ganga B Treating it as the main stream of Indus C Treating it as a distributary of Narmada D Treating it as a bay of Sundarbans
Correct answer: A Son joins the Ganga system from the southern side. Exam tip: separate northern and southern tributaries of Ganga.

Which statement makes the comparison between Himalayan and Peninsular river systems most accurate? A Himalayan rivers are linked with relatively young dynamic terrain while Peninsular rivers are linked with old stable plateau B Both are driven only by sea tides C Only Peninsular rivers form Himalayan gorges D Himalayan rivers never enter plains
Correct answer: A Age and slope of land change river system character. Exam tip: consider geology in comparisons.

How do a large catchment and many tributaries affect a river system? A They always make the river dry B They can increase water and sediment supply to the main river C They make the river flow backward from the sea D They make every river a glacier
Correct answer: B A large basin and tributaries increase the extent of a river system. Exam tip: connect catchment with water volume.

Why is looking only at rainfall incomplete in flood risk analysis? A Because the river name alone decides floods B Because sea colour alone creates floods C Because basin size, slope, sediment and tributaries also influence floods D Because flood has no relation with rivers
Correct answer: C Rainfall is important, but it alone does not determine flood risk. Basin size, slope, extra water brought by tributaries, sediment deposition in the channel, and drainage capacity affect runoff and river level. Therefore, option C is correct. Rainfall alone cannot show how quickly water will flow or how much water a river channel can hold. Exam tip: For flood-related answers, link rainfall with relief, river-system features, and sedimentation.

If river velocity decreases but sediment load is high, which process is more likely? A Vertical erosion B Marine salinity C Land uplift D Deposition
Correct answer: D When velocity decreases, a river deposits sediments. Exam tip: connect delta and flood plain with deposition.

Study of drainage patterns tells not only river direction but also what else? A Relief and rock structure B Only number of animals C Only market prices D Only daily temperature
Correct answer: A Patterns indicate slope rock type and structural control. Exam tip: identify patterns with reasons.
