Explanation:
Black soil is formed through the weathering of basaltic rocks, not from alluvial deposits. It has developed extensively in the moderately rainy Deccan Trap region.
Question 21: Choose the correct answer from the following statements. (1) The orientation of the Aravalli Range is nearly parallel to the direction of the Southwest Monsoon winds. (2) This is why the Aravalli Range is unable to obstruct the monsoon winds effectively. (3) If the Aravalli Range were oriented perpendicular to the monsoon winds like the Western Ghats, western Rajasthan could have received more rainfall than at present.
Correct Answer:
C
— 1, 2 and 3
Explanation:
The Aravalli Range extends in a southwest–northeast direction, which is nearly parallel to the advancing Southwest Monsoon winds. Consequently, it provides little orographic obstruction, allowing much of the moisture to pass without causing significant rainfall over western Rajasthan. Had the Aravallis been oriented more nearly perpendicular to the monsoon winds, they could have produced greater orographic rainfall over the region.
Question 22: Which of the following landform–characteristic pairs are correctly matched? (1) Bhangar – Old alluvial plain (2) Khadar – New alluvial plain (3) Bhabar – Pebbly belt south of the Shiwaliks (4) Terai – Marshy belt south of the Bhabar where groundwater re-emerges at the surface
Correct Answer:
C
— 1, 2, 3 and 4
Explanation:
All four pairs are correctly matched. The Terai is the highly moist belt south of the Bhabar where groundwater reappears at the surface. Historically, it was marshy, although much of it is now under cultivation.

(2) The impact of El Niño on the Indian monsoon is not the same every year. (3) The Indian monsoon is controlled by only one oceanic phenomenon.
Correct Answer:
A
— 1 and 2 only
Explanation:
The Indian monsoon is influenced by ENSO, IOD, snow cover, land-sea thermal contrast, and several other atmospheric factors. Therefore, Statement 3 is incorrect.
Question 29: Choose the correct answer from the following statements. (1) Black soil in India is mainly distributed over regions underlain by basaltic rocks. (2) The high clay content of black soil enables it to retain more moisture. (3) Black soil is more famous for cotton cultivation than for rice cultivation.
Correct Answer:
C
— 1, 2 and 3
Explanation:
All three statements are correct. Black soil developed over the Deccan Trap region and is rich in montmorillonite clay minerals, giving it high moisture-retaining capacity. It is well known for cotton cultivation.
Question 30: Which of the following landform–formation cause pairs are correctly matched? (1) Deccan Traps – Massive basaltic volcanic eruptions (2) Indo-Gangetic Plain – Fluvial deposition (3) Thar Desert – Rain shadow effect only (4) Narmada Valley – Faulting
Correct Answer:
A
— 1, 2 and 4 only
Explanation:
The Deccan Traps were formed by extensive lava flows, the Indo-Gangetic Plain by fluvial deposition, and the Narmada Valley by faulting. The Thar Desert was not formed solely due to the rain shadow effect; subtropical high pressure, continentality, the orientation of the Aravalli Range, and other factors also contributed.
Question 31: Choose the correct answer from the following statements. (1) The Western Ghats constitute one of the biodiversity hotspots of the world. (2) The Western Ghats form a major watershed of Peninsular India. (3) The western slope of the Western Ghats generally receives more rainfall than the eastern slope. (4) All rivers originating in the Western Ghats drain into the Arabian Sea.
Correct Answer:
A
— 1, 2 and 3 only
Explanation:
The Western Ghats are recognised as one of the world's biodiversity hotspots. They form the principal watershed of Peninsular India, separating rivers flowing towards the Arabian Sea from those flowing towards the Bay of Bengal. The western slope receives much heavier rainfall because of orographic uplift. Statement (4) is incorrect because several major east-flowing rivers such as the Godavari, Krishna, and Kaveri originate in the Western Ghats but drain into the Bay of Bengal.
Question 32: Which of the following statements is/are correct? (1) The Himalayas reduce the impact of extremely cold winds from Central Asia on the Indian subcontinent during winter. (2) If the Himalayas did not exist, the present form of the Southwest Monsoon over India would not have developed. (3) The influence of the Himalayas is limited only to climate and does not extend to the drainage system.
Correct Answer:
A
— 1 and 2 only
Explanation:
The Himalayas influence India's climate, monsoon, and river systems. They block the cold continental winds from Central Asia and obstruct the monsoon winds, thereby facilitating rainfall. Statement 3 is incorrect because the Himalayas are also the source of India's major river systems.

Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Western Ghats lie very close to the western coast, making the western coastal plains comparatively narrow. This topographic setting directly influences the width of the coastal plains. Therefore, the reason correctly explains the assertion.
Question 145: Assertion (A): The distribution of mineral resources in India influences the country's industrial pattern. Reason (R): Heavy industries are generally established near the sources of raw materials.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The localization of heavy industries, such as the iron and steel industry, is closely associated with the availability of mineral resources. Jharkhand, Odisha, and Chhattisgarh are excellent examples of this pattern. The reason directly explains the assertion.
Question 146: Assertion (A): All perennial rivers of India are glacier-fed. Reason (R): Some rivers, though primarily rain-fed, maintain perennial flow due to sustained rainfall, groundwater contribution, and large catchment areas.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Not all perennial rivers in India originate from glaciers. Several rivers, particularly in high-rainfall regions, remain perennial because of continuous rainfall, groundwater recharge, springs, and extensive catchment areas. Therefore, the assertion is incorrect, whereas the reason is correct.
Question 147: Assertion (A): Both the Western Ghats and the Himalayas influence the distribution of rainfall in India. Reason (R): Both mountain systems act as physical barriers in the path of moisture-laden winds.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Himalayas and the Western Ghats are the major topographic barriers controlling India's rainfall pattern. The Western Ghats cause orographic rainfall from the Arabian Sea branch of the monsoon, while the Himalayas prevent the monsoon winds from escaping northward, thereby enhancing rainfall over northern India. Hence, the reason correctly explains the assertion.
Question 148: Assertion (A): Not all deltas in India expand towards the sea at the same rate. Reason (R): Delta growth is influenced by the sediment brought by rivers, sea waves, tides, and coastal currents.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The rate of growth varies among different deltas because it depends on the quantity of sediment, sea waves, tidal influences, coastal currents, and other marine processes. Therefore, the reason correctly explains the assertion.
Question 149: Assertion (A): If the Himalayas did not exist, the Indian Summer Monsoon would not have developed in its present form. Reason (R): The development of the Indian Monsoon depends only on the thermal contrast between land and sea.
Correct Answer:
C
— A is correct, but R is incorrect.
Explanation:
The Himalayas play a crucial role in the development of the Indian Monsoon, its intensity, and the distribution of rainfall. In their absence, the monsoon could not have evolved in its present form. However, the monsoon does not depend solely on the thermal contrast between land and sea; the Himalayas, the Tibetan Plateau, the ITCZ, jet streams, pressure gradients, and oceanic conditions also play significant roles. Therefore, the assertion is correct, whereas the reason is incorrect.
Question 150: Assertion (A): The development of road transport in India is confined only to the plains. Reason (R): Road construction in mountainous regions is technically more challenging.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Road transport in India has also developed extensively in mountainous, border, and remote regions. Although road construction in mountainous areas is technically difficult and expensive, a wide road network has nevertheless been developed there. Therefore, the assertion is incorrect, whereas the reason is correct.
Question 151: Assertion (A): Rivers in the Peninsular Plateau of India generally flow through stable valleys. Reason (R): This region is composed of very ancient and hard rocks.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Peninsular India is geologically a very ancient and stable landmass. The rivers here flow through mature valleys, and changes in their courses are comparatively limited. The reason scientifically explains this characteristic.
Question 152: Assertion (A): The Thar Desert of India has formed solely due to low rainfall. Reason (R): The rain-shadow effect, subtropical high pressure, continentality, and monsoonal limitations also contribute to its development.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
The Thar Desert has not formed solely because of low rainfall. Its development is the result of the combined influence of several geographical and climatic factors. Therefore, the assertion is incorrect, whereas the reason is correct.
Question 153: Assertion (A): Not all rivers of India ultimately drain into the Bay of Bengal. Reason (R): While most Peninsular rivers flow eastwards due to the general eastward slope of the Peninsular Plateau, several rivers such as the Narmada, Tapi, Mahi, and Sabarmati drain into the Arabian Sea.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Most Peninsular rivers flow eastwards and drain into the Bay of Bengal because of the general eastward slope of the Peninsular Plateau. However, the Narmada, Tapi, Mahi, and Sabarmati flow westwards into the Arabian Sea through rift valleys or westward slopes. Hence, the reason correctly explains why not all Indian rivers drain into the Bay of Bengal.
Question 154: Assertion (A): Most major cities of India historically developed along rivers or other reliable water sources. Reason (R): River banks provided favourable conditions for early settlements due to the availability of water, fertile land, and transport facilities.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Many important Indian cities such as Delhi (Yamuna), Kolkata (Hooghly), Patna (Ganga), Kanpur (Ganga), Varanasi (Ganga), Ahmedabad (Sabarmati), Guwahati (Brahmaputra), and Srinagar (Jhelum) historically developed along rivers because rivers provided water, fertile land, transportation, and trade opportunities. Therefore, the reason correctly explains the assertion.
Question 155: Assertion (A): Most coalfields of India are located in Peninsular India. Reason (R): The Gondwana sedimentary basins were predominantly developed in Peninsular India.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Major Gondwana coalfields of India, such as Jharia, Raniganj, Bokaro, Korba, and Singrauli, are associated with the ancient sedimentary basins of Peninsular India. Therefore, both the assertion and the reason are correct, and the reason correctly explains the assertion.
Question 156: Assertion (A): Red soil is generally highly fertile. Reason (R): The presence of iron oxide in red soil is responsible for its red colour.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Red soil is not naturally highly fertile. Its red colour is due to the presence of iron oxide. Therefore, the assertion is incorrect, whereas the reason is correct.
Question 157: Assertion (A): The leeward slope of the Western Ghats receives comparatively less rainfall. Reason (R): After crossing the mountains, the monsoon winds have already lost most of their moisture.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The windward slope of the Western Ghats receives orographic rainfall. After crossing the mountains, the air loses much of its moisture, causing the leeward slope to become a rain-shadow region. Hence, the reason correctly explains the assertion.
Question 158: Assertion (A): All Himalayan rivers always carry an equal volume of water. Reason (R): Himalayan rivers receive water from glaciers as well as rainfall.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Himalayan rivers are perennial, but they do not all carry the same volume of water because their catchment areas, glacial contributions, and rainfall vary. The reason is correct because Himalayan rivers receive water from both glacier melt and monsoonal rainfall.
Question 159: Assertion (A): In the Northern Plains of India, the average annual rainfall generally increases from west to east. Reason (R): As the Bay of Bengal branch advances towards the west and northwest, it gradually loses its moisture.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Rainfall increases from west to east due to the stronger influence of the Bay of Bengal branch. As the monsoon winds move towards the west and northwest, they gradually lose their moisture. Therefore, the eastern regions receive higher rainfall, while the western regions receive comparatively less rainfall.
Question 160: Assertion (A): The development of irrigated agriculture in India has taken place only in low-rainfall regions. Reason (R): Irrigation is also used to address rainfall uncertainty, promote crop diversification, and support multiple cropping.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Assertion (A) is incorrect because irrigation is not confined only to low-rainfall regions. Even in areas receiving adequate rainfall, irrigation is widely used for rabi crops, achieving higher productivity, promoting multiple cropping and crop diversification, and reducing the risks associated with uncertain rainfall. Therefore, the reason is correct, whereas the assertion is incorrect.
Question 161: Assertion (A): Most industrial regions in India have developed near transport facilities. Reason (R): The availability of raw materials, labour, markets, and transport influences the location of industries.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Transport, raw materials, energy, labour, and markets are all important factors influencing industrial location. Therefore, most industrial regions have developed near transport networks. The reason appropriately explains this fact because transport affects both production costs and marketing.
Question 162: Assertion (A): The Eastern Coastal Plains are narrower than the Western Coastal Plains. Reason (R): Most major east-flowing rivers form extensive deltas along the eastern coast.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
The assertion is incorrect because the Eastern Coastal Plains are generally broader than the Western Coastal Plains. Major east-flowing rivers such as the Mahanadi, Godavari, Krishna, and Kaveri deposit large quantities of sediments and form extensive deltas, which broaden the eastern coastal plains. Hence, the reason is correct, whereas the assertion is incorrect.
Question 163: Assertion (A): All mineral resources of India are found in sedimentary rocks. Reason (R): Major minerals such as iron ore are primarily associated with ancient igneous and metamorphic rocks.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Assertion (A) is incorrect because not all mineral resources of India occur in sedimentary rocks. Many metallic minerals, such as iron ore, manganese, copper, and gold, are primarily associated with ancient igneous and metamorphic rocks. On the other hand, coal, petroleum, and natural gas are mainly found in sedimentary rocks. Therefore, the reason is correct, whereas the assertion is incorrect.
Question 164: Assertion (A): The Arabian Sea branch of the Southwest Monsoon causes heavy rainfall after striking the Western Ghats. Reason (R): Due to the mountain barrier, moisture-laden air is forced to rise, cools, condenses, and produces rainfall.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Arabian Sea branch of the Southwest Monsoon produces orographic rainfall after striking the Western Ghats. As the moisture-laden air rises along the mountain slopes, it cools, condenses, and results in rainfall. Therefore, the reason is the scientific explanation of the assertion.
Question 165: Assertion (A): The distribution of population in India is not uniform. Reason (R): Relief, availability of water, climate, and economic opportunities influence population distribution.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The distribution of population in India is highly uneven. Population density is very high in the Indo-Gangetic Plains, whereas it is relatively low in the Himalayas, the Thar Desert, and densely forested regions. This uneven distribution is influenced by factors such as relief, climate, water availability, soil fertility, and economic opportunities. Therefore, the reason appropriately explains the assertion. Although social and historical factors also have an impact, the factors mentioned in the reason sufficiently explain the assertion.
Question 166: Assertion (A): Black soil has a high water-holding capacity. Reason (R): Black soil contains a very high proportion of sand.
Correct Answer:
C
— A is correct, but R is incorrect.
Explanation:
Black soil has a very high water-holding capacity due to its high clay content. Hence, the assertion is correct. The reason is incorrect because a higher proportion of sand generally reduces the water-holding capacity of soil.
Question 167: Assertion (A): All west-flowing rivers of India form deltas. Reason (R): West-flowing rivers generally have steeper gradients than the major east-flowing rivers.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
The assertion is incorrect because major west-flowing rivers such as the Narmada and Tapi generally form estuaries rather than deltas. The reason is correct, as these rivers usually have steeper gradients, limiting sediment deposition near their mouths. In addition, the narrow continental shelf and strong marine currents also discourage delta formation.
Question 168: Assertion (A): The Himalayas provide partial protection to the Indian subcontinent from the extremely cold winds of Central Asia. Reason (R): The Himalayas act as a massive mountain barrier.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Himalayas are the principal physical barrier controlling India's climate. They effectively block the extremely cold and dry winds originating from Central Asia, keeping northern India comparatively warmer. The reason directly explains this effect; therefore, both statements are correct, and the reason is the appropriate explanation of the assertion.
Question 169: Assertion (A): The Eastern Ghats are more fragmented and discontinuous than the Western Ghats. Reason (R): Rivers such as the Mahanadi, Godavari, Krishna, and Kaveri have cut across the Eastern Ghats at several places.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Eastern Ghats are older, highly eroded, and discontinuous mountain ranges. Major east-flowing rivers such as the Mahanadi, Godavari, Krishna, and Kaveri have cut through them, breaking their continuity. Thus, both the assertion and the reason are correct, and the reason appropriately explains the assertion.
Question 170: Assertion (A): All plateaus of India are rich in mineral resources. Reason (R): The ancient geological structure of Peninsular India is favourable for the occurrence of numerous minerals.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Not all plateaus in India are equally rich in mineral resources; therefore, the assertion is incorrect. The ancient hard rock region of Peninsular India is rich in iron ore, manganese, bauxite, mica, and several other minerals. Hence, the reason is correct.
Question 171: Assertion (A): Most of India's annual rainfall is received from the Southwest Monsoon. Reason (R): The Southwest Monsoon derives moisture from the Arabian Sea and the Bay of Bengal.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
Nearly 75–80% of India's annual rainfall is received during the Southwest Monsoon season. The Arabian Sea and Bay of Bengal branches carry abundant moisture onto the Indian subcontinent, making the Southwest Monsoon the principal source of rainfall over most parts of India. Therefore, both the assertion and the reason are correct, and the reason correctly explains the assertion.
Question 172: Assertion (A): Most river valleys in India have been favourable for human settlement. Reason (R): River valleys provide water, fertile soil, and level land.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
River valleys provide water, fertile alluvial soil, and level land, which have promoted the development of agriculture, transportation, and human settlements. Therefore, both the assertion and the reason are correct, and the reason correctly explains the assertion.
Question 173: Assertion (A): The region receiving the highest rainfall in India is Western Rajasthan. Reason (R): The influence of the Southwest Monsoon is comparatively weak in Western Rajasthan.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
The region receiving the highest rainfall in India is the Mawsynram–Cherrapunji region of Meghalaya; therefore, the assertion is incorrect. The influence of the Southwest Monsoon is comparatively weak in Western Rajasthan, and due to its geographical conditions, the region receives very little rainfall. Hence, the reason is correct.
Question 174: Assertion (A): The black soil of India has mainly been formed from Himalayan alluvial deposits. Reason (R): Black soil is primarily associated with the weathering of basaltic lava rocks.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Black soil has not been formed from Himalayan alluvium but from the weathering of the basaltic lava rocks of the Deccan Trap. Therefore, the assertion is incorrect, whereas the reason is correct.
Question 175: Assertion (A): The windward slope of the Western Ghats receives heavy rainfall. Reason (R): The Southwest Monsoon winds rise after striking the Western Ghats.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Western Ghats obstruct the Southwest Monsoon winds, forcing them to ascend, cool, and produce orographic rainfall. Therefore, both the assertion and the reason are correct, and the reason correctly explains the assertion.
Question 176: Assertion (A): The Tropic of Cancer passes through approximately the central part of India. Reason (R): The Tropic of Cancer divides India into almost two equal halves.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Tropic of Cancer (23°30′ N) passes through the central part of India and divides the country into almost two equal halves. Therefore, both the assertion and the reason are correct, and the reason correctly explains the assertion.
Question 177: Assertion (A): All rivers in India form deltas. Reason (R): Some rivers form estuaries due to steep gradients and strong tidal action.
Correct Answer:
D
— A is incorrect, but R is correct.
Explanation:
Not all rivers form deltas. Rivers such as the Narmada and the Tapi form estuaries before entering the Arabian Sea. The reason is correct because steep gradients, relatively lower deposition, and strong tidal influence can inhibit delta formation.
Question 178: Assertion (A): The Western Ghats are the highest mountain range in Peninsular India. Reason (R): The average elevation of the Western Ghats is higher than that of the Eastern Ghats.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Western Ghats have a significantly higher average elevation (about 900–1600 m) than the Eastern Ghats, which are lower and highly discontinuous. Consequently, the Western Ghats constitute the highest mountain range of Peninsular India. Hence, both the assertion and the reason are correct, and the reason correctly explains the assertion.
Question 179: Assertion (A): Most of the Northern Plains of India have been formed by alluvial deposits brought by rivers. Reason (R): Himalayan and Peninsular rivers carry sediments and deposit them in the plains.
Correct Answer:
A
— Both A and R are correct, and R is the correct explanation of A.
Explanation:
The Northern Plains have primarily been formed through the long-term deposition of alluvial sediments carried by the Himalayan rivers and some Peninsular rivers. Therefore, the assertion is correct. The reason is also correct because this depositional process is the fundamental cause behind the formation of the plains.
