Question 1 Expert Level 21
Why does the Khadar region become more suitable for farming after floods? A Fresh fertile silt gets deposited B Salt completely disappears from soil C Rocky surface comes upward D Rainfall always stops
Correct answer: A Floods bring fresh silt to Khadar and make the soil fertile. In exams, identify Khadar with new alluvium.

Which is the strongest geographical reason for the dense population of the Northern Plains? A Level land fertile soil and water availability B High mountains and permanent snow C Desert climate and sand D Hard lava surface and low water
Correct answer: A Level land, fertile alluvial soil and water have promoted settlement. In exams, link population with agriculture and water.

How does the very gentle slope of the Northern Plains affect river behaviour? A Rivers form meanders B Rivers cut straight deep valleys C Rivers carry lava D Rivers become glaciers
Correct answer: A A gentle slope slows rivers and promotes meanders. In exams, connect gentle plain slope with meanders.

What is a lake formed by a cut-off old river channel called in plains? A Oxbow lake B Lagoon C Glacial lake D Crater lake
Correct answer: A An oxbow lake forms when a meander gets cut off. In exams, remember it as a common floodplain river feature.

What kind of surface do flood plains represent in the Northern Plains? A Area periodically flooded and deposited by rivers B Permanently snow-covered area C Hard igneous rock area D Marine coral area
Correct answer: A Flood plains form through river overflow and deposition. In exams, treat them as active surfaces of fluvial deposition.

Why is the alluvial soil layer very thick in the Northern Plains? A Himalayan rivers deposited sediments for a long time B Deccan lava repeatedly flowed C Sea waves kept raising mountains D Desert winds kept forming ice
Correct answer: A Himalayan rivers brought and deposited huge sediments over a long period. In exams, link thick alluvium with long-term deposition.

Which three major river systems together formed the Northern Plains? A Indus Ganga and Brahmaputra B Narmada Tapi and Sabarmati C Mahanadi Godavari and Kaveri D Luni Banas and Mahi
Correct answer: A The Northern Plains were mainly formed by deposits of the Indus, Ganga and Brahmaputra systems. In exams, treat these three as the base.

Why does the width of the Northern Plains vary from place to place? A Variation in river deposition relief and Himalayan front B Uniform marine erosion everywhere C Only uniform thickness of lava layers D Equal desert dunes everywhere
Correct answer: A The width varies due to differences in river deposition and relief. In exams, do not treat it as a uniform belt.

What does the location of Bhabar south of the Shiwalik indicate? A Deposition of coarse sediments in foothill zone B Deposition of fine sand on coast C Thick lava layer on plateau D Loess deposition in desert
Correct answer: A Rivers descending from the Shiwalik deposit coarse sediments in the foothill zone. In exams, link Bhabar with Himalayan foothills.

The abundance of meanders in river plains shows which change in river energy? A Increase in lateral erosion and deposition B Extreme increase in vertical erosion C Increase in glacial abrasion D Permanence of sea tides
Correct answer: A In plains, a river erodes one bank and deposits on the other. In exams, connect meanders with lateral erosion.

Which reason is most important in making the Ganga-Brahmaputra Delta very extensive? A Huge sediment load and deposition by distributaries B Uplift of hard granite C Low water and high evaporation D Direct scraping by glaciers
Correct answer: A The Ganga and Brahmaputra bring heavy sediments and form a delta through distributaries. In exams, link delta with sediment deposition.

What type of land is formed by the network of river branches and sub-branches in the Northern Plains? A Alluvial flood plain B Lava plateau C Glacial moraine D Coral island
Correct answer: A River branches spread sediments and form alluvial flood plains. In exams, understand branching systems through deposition.

If old alluvium is found on a higher surface, it most closely matches which feature? A Bhangar B Khadar C Terai D Bhabar
Correct answer: A Bhangar is a relatively higher surface of old alluvium. In exams, higher old plain is treated as Bhangar.
View question details Question 14 Expert Level 21
If a river deposits new fine sediments every year, that area belongs to which category? A Khadar B Bhangar C Bhabar D Plateau
Correct answer: A Khadar is new alluvium often renewed by floods. In exams, identify fresh fine deposition as Khadar.

What is the main basis of agricultural diversity in the Northern Plains? A Level land fertile soil and irrigation facility B Snowy slopes and thin soil C Lava flows and mineral dust D Only coastal fishing
Correct answer: A The level surface and alluvial soil make farming diverse in these plains. In exams, link agricultural potential with physical base.

Why has it been easier to develop transport routes in the plains of North India? A Due to level surface and low slope B Due to permanent snow and deep gorges C Due to many volcanic craters D Due to constant sea waves
Correct answer: A Level plains are favourable for road and rail construction. In exams, connect transport with relief.
View question details Question 17 Expert Level 21
Which statement best explains the role of the Himalayas in forming the Northern Plains? A Himalayan rivers deposited heavy sediments in the plains B The Himalayas spread lava in the plains C The Himalayas formed marine corals D The Himalayas formed desert dunes
Correct answer: A Rivers rising from the Himalayas bring sediments and build plains. In exams, link mountain source with plain deposition.

Which sequence of natural belts from the Himalayas southward is correct? A Bhabar Terai Bhangar and Khadar B Khadar Bhabar Terai and Bhangar C Terai Khadar Bhabar and Bhangar D Bhangar Terai Khadar and Bhabar
Correct answer: A From the Himalayas southward, Bhabar comes first, then Terai and then alluvial plains. In exams, remember the belt sequence.
View question details Question 19 Expert Level 21
Which hazard becomes most likely when rivers change their course in plains? A Flood and erosion B Seismic volcanism C Avalanche D Coral bleaching
Correct answer: A When a river changes course, it can cause erosion and floods in new areas. In exams, link shifting channels with disaster risk.

What is the physical basis for calling the Northern Plains the granary of India? A Fertile alluvial soil and sufficient water B Hard basalt and low rainfall C High mountains and snow D Sandy soil and saline water
Correct answer: A Alluvial soil and river water make farming highly productive. In exams, link grain production with the fertility of the plains.
