Question 1 Expert Level 21
Which feature makes perennial rivers especially important in the Northern Plains? A Water supply from Himalayan snow and rainfall B Water only from sea tides C Water from lava lakes D Water from desert dew
Correct answer: A Himalayan rivers are fed by both snow and rainfall. In exams, link perennial flow with irrigation and settlement.

If a question mentions fine soil brought by rivers, which term is it most closely related to? A Alluvium B Basalt C Granite D Coral
Correct answer: A Fine fertile soil brought by rivers is called alluvium. In exams, remember rivers and alluvium together.

Why does deposition increase in the lower course of rivers in the Northern Plains? A Velocity decreases due to gentle slope B Velocity increases due to steep slope C River stops due to freezing D River heats due to lava
Correct answer: A On a gentle slope, a river loses carrying capacity and deposits more. In exams, link reduced velocity with deposition.

Which risk is also associated with fertile soil in flood plains? A Possibility of repeated floods B Spread of permanent glacier C Volcanic eruption D Annual sea tsunami
Correct answer: A Flood plains are fertile but are affected by river overflow. In exams, remember both benefit and risk.

Why was natural vegetation dense in the Terai? A Moisture marshes and water availability were high B Soil was very dry and saline C It was covered with permanent snow D Lava surface prevented forests
Correct answer: A Terai had dense forests due to high moisture and water availability. In exams, link Terai with biodiversity and moisture.

Why is farming relatively difficult in Bhabar? A Coarse pebbles and seepage of water B Annual deposition of fresh silt C Very deep black soil D Entry of sea water
Correct answer: A The pebbly surface and water seepage in Bhabar limit farming. In exams, remember Bhabar as less suitable for agriculture.
View question details Question 7 Expert Level 21
Why do relatively coarser deposits settle first along river banks instead of finer deposits? A Heavier particles settle first during floods B Lighter particles always settle first C River carries only rocks D Soil comes from volcanoes
Correct answer: A As flood water spreads, river energy falls and heavier particles settle first. In exams, remember the process of natural levee formation.

Where are alluvial fans most likely to form in the Northern Plains region? A Where rivers descend from mountains to plains B On the deep sea floor C In the middle of a desert D On a coral reef
Correct answer: A When a river descends from mountains to plains, reduced velocity spreads sediments. In exams, link alluvial fans with foothill zones.

Why can floods be more intense in parts of the Brahmaputra Plain than in the Ganga Plain? A Very high water sediment load and shifting channel B Very low rainfall and dryness C Regular lava flow D Level area with permanent snow cover
Correct answer: A The Brahmaputra carries heavy water and sediments and often shifts course. In exams, remember floods as a major feature in Assam.

Why is river deposition considered more active in the eastern part of the Ganga Plain? A Rivers carry higher water and sediment load B No river flows there C Only lava rocks are present there D Marine glaciers are present there
Correct answer: A In the eastern Ganga Plain, rivers carry more water and sediments and build flood plains. In exams, understand the eastern part as more flood affected.

Which natural process renews soil in the Northern Plains? A Deposition of fresh alluvial silt by floods B Cooling of lava C Glacier freezing on mountain D Growth of marine coral
Correct answer: A Floods renew soil by depositing fresh silt. In exams, treat floods not only as hazards but also as deposition processes.
View question details Question 12 Expert Level 21
Under which condition does a river start forming a network-like pattern of branches in plains? A When sediment load is high and slope is low B When slope is very steep and sediment is absent C When river completely freezes D When sea waves stop the river
Correct answer: A Low slope and high sediment load can divide a river into branches. In exams, link it with a deposition-dominant condition.

Which part of the Northern Plains can be considered relatively the newest and most active depositional area? A Khadar B Bhangar C Bhabar D Shiwalik
Correct answer: A Khadar near rivers is a new and active alluvial zone. In exams, remember Khadar as recent and more fertile.

What is the most direct relation between human settlement and river systems in the Northern Plains? A Rivers provide water soil and transport facilities B Rivers provide only petroleum C Rivers create icy walls D Rivers create marine corals
Correct answer: A River systems provided water, fertile soil and routes. In exams, link settlement with river resources.

What is the best reason to study Bhabar and Terai together? A They show a clear underground and surface water relation B Both are marine coral areas C Both are lava plateaus D Both are dry deserts
Correct answer: A Water sinks in Bhabar and reappears in Terai. In exams, remember both by their sequence and water behaviour.
View question details Question 16 Expert Level 21
Which statement best explains the economic importance of the Northern Plains? A They are favourable for agriculture transport and dense settlement B They are famous only for mineral mining C They are permanent snowy pastures D They are marine fishing zones
Correct answer: A The level surface and fertility of the Northern Plains strengthen the economy. In exams, keep agriculture and transport as key points.

If meanders, natural levees and oxbow lakes are found in a river plain, what kind of river work do they indicate? A Both fluvial erosion and deposition B Only volcanic eruption C Only glacial accumulation D Only marine coral growth
Correct answer: A These features form through both erosion and deposition by rivers. In exams, treat river landforms in plains as combined processes.
View question details Question 18 Expert Level 21
Why is it geographically incorrect to treat the Northern Plains as a uniform plain? A They include Bhabar Terai Bhangar Khadar and distinct river plains B They have no rivers C They are made of only one rock D They are completely under the sea
Correct answer: A The Northern Plains have several physical subdivisions and river systems. In exams, understand them as plains with diverse landforms.
View question details Question 19 Expert Level 21
How can old river courses be identified when rivers change their path in the Northern Plains? A Lava domes B Old channels oxbow lakes and sediment marks C Marine coral belts D Permanent snow lines
Correct answer: B When rivers shift, old channels and oxbow lakes indicate former courses. In exams, link shifting channels with floodplain evidence.

Why is the Khadar region considered more fertile than Bhangar in the Northern Plains? A Abundance of hard limestone B Thick layer of old kankar deposits C Regular deposition of new alluvium by rivers D Rapid weathering of lava rocks
Correct answer: C Rivers repeatedly deposit fresh silt and alluvium in Khadar. In exams, remember Khadar as a newer and more fertile alluvial zone.
