Why are kankar nodules sometimes found in Bhangar land of the Northern Plains? A Because it is older alluvium where calcium deposits form B Because it is a new sea coast C Because it is glacial ice D Because it is active lava flow
Correct answer: A Kankar nodules may occur in older Bhangar alluvium. Exam tip: treat kankar as an identifying feature of Bhangar.

Why is Khadar considered more suitable for cultivation than Bhangar? A Because it is high rocky land B Because it has new and repeatedly renewed alluvial soil C Because it is completely desertic D Because it has more sea salt
Correct answer: B Floods keep bringing new fertile soil to Khadar. Exam tip: remember Khadar as better for farming.

Under which condition do natural levees form in the Northern Plains? A When a river leaves coarse deposits along banks during floods B When wind deposits sand on mountain peaks C When a glacier deepens a valley D When corals grow in the sea
Correct answer: A During floods, rivers deposit more material near banks and form levees. Exam tip: link levees with flood deposition.

What is the combined impact of the level surface of the Northern Plains on transport and agriculture? A It makes expansion of roads, railways and irrigation easier B It makes all settlements impossible C It limits agriculture only to pastoralism D It permanently dries rivers
Correct answer: A Level land helps develop transport and irrigation networks easily. Exam tip: connect level plains with economic development.

If rivers split into many channels and deposit sand and silt, this may be a feature of which plain? A Only hard plateau plain B An active alluvial plain like the Brahmaputra Plain C Only coastal coral plain D Permanent ice plain
Correct answer: B Channel shifting and deposition are common in the Brahmaputra Plain. Exam tip: link braided flow with active alluvial plains.

What is the most balanced relationship between floods and soil fertility in the Northern Plains? A Floods only cause damage and leave no deposits B Floods always permanently save all crops C Floods create risk and also bring new alluvial soil D Floods have no relation with plain formation
Correct answer: C Floods can cause damage but also deposit fertile silt. Exam tip: give a balanced analysis rather than a one-sided answer.

The formation of the Ganga Brahmaputra Delta is most directly related to which process? A Deposition of sediments by rivers near the sea B Volcanic eruption of mountains C Formation of desert dunes D Formation of moraine by glaciers
Correct answer: A Rivers form deltas by depositing silt and sediments near their mouths. Exam tip: connect delta with deposition at river mouth.
View question details Question 13 Expert Level 19
Why can the Northern Plains be considered physically young and dynamic? A Because rivers still cause floods, deposition and channel shifting B Because no river flows here C Because it is entirely ancient hard rock D Because it is only a marine island
Correct answer: A River processes still modify landforms in the plains. Exam tip: connect dynamism with active river action.

In which part of the Northern Plains is the thickness of alluvial deposits likely to be very high? A In river valleys and sedimentary basins B On high snow peaks C On hard Peninsular plateau D On coral reefs
Correct answer: A Long-term deposition creates thick alluvial layers in the plains. Exam tip: understand the plain as sedimentary filling.

What do subunits like Bhabar Terai Khadar and Bhangar prove? A The Northern Plain is not completely uniform B There are no rivers in the Northern Plain C The Northern Plain is only mountains D The Northern Plain is under the sea
Correct answer: A These belts show the internal diversity of the plain. Exam tip: do not treat the Northern Plain as uniform.
View question details Question 16 Expert Level 19
Which group best identifies landforms made by rivers in the Northern Plains? A Meanders, oxbow lakes and natural levees B Volcanoes, craters and lava domes C Glaciers, eskers and ice caps D Coral, lagoon and sea cliff
Correct answer: A All these are plain landforms related to river action. Exam tip: distinguish river landforms from volcanic or glacial landforms.

Which combination best explains the agricultural potential of the Ganga Plain? A Alluvial soil, adequate water and level land B Lava soil, steep slope and drought C Sandy soil, saline water and sea storms D Icy land, low temperature and thin soil
Correct answer: A Fertile soil and water availability support agriculture in the Ganga Plain. Exam tip: link agricultural potential with physical resources.
View question details Question 18 Expert Level 19
What is one geographical reason for the development of many large towns in the Northern Plains? A Rocky slopes and little water B Level land, transport ease and agricultural surplus C Permanent snow cover and isolation D Coral islands and marine isolation
Correct answer: B Level and fertile plains support trade and settlement. Exam tip: connect urban growth with agriculture and transport.
View question details Question 19 Expert Level 19
Why do the width and extent of the Northern Plains vary regionally? A Because river deposits, slope and surrounding relief vary B Because identical glaciers exist everywhere C Because the plain is made by only one river D Because the sea covers the entire plain
Correct answer: A The form of the plain varies with river systems and relief. Exam tip: explain regional variation through physical factors.
