Mountains and Plateaus of India

Correct answer: C. Satpura

The correct answer is the Satpura Range. The Mahadeo Hills are an important section of the Satpura mountain system in central India, particularly in the region of Madhya Pradesh. This association is based on physical geography: Mahadeo is not an independent national mountain system comparable with the Himalayas or the Aravallis, but a named hill group within the Satpura region. The Aravallis run mainly across western and north-western India, while the Eastern Ghats occur along the eastern side of the peninsula. Since the question asks for the larger range containing the Mahadeo Hills, option C is correct.

Correct answer: D. Satpura

The correct answer is Satpura. The Maikal Range is generally treated as the eastern extension or eastern section of the Satpura mountain system in central India. It is closely connected with the Amarkantak highlands, where important rivers such as the Narmada and Son originate. Nilgiri belongs to the southern Western Ghats, Karakoram is a high mountain system of the trans-Himalayan region, and Pir Panjal is a sub-range of the western Himalayas. These ranges are geographically separate from Maikal. Therefore, identifying the broader regional system rather than a nearby town or river leads to option D.

Correct answer: A. Narmada

The correct answer is the Narmada River. The Amarkantak highland, located near the meeting region of the Maikal and Satpura systems, is widely recognized as the source area of the Narmada. The river then flows westward through a rift valley before entering the Arabian Sea. The same highland is also associated with the source of the Son River, but that fact does not change the answer because the question specifically asks for the river represented in option A. The Yamuna rises in the Yamunotri region of the Himalayas, the Brahmaputra in the Tibetan-Himalayan region, and the Cauvery in the Western Ghats. Hence, option A is correct.

Correct answer: B. Fold mountains

The correct answer is fold mountains. The Himalayas formed when the Indian tectonic plate moved northward and collided with the Eurasian plate. Sedimentary layers deposited in the former Tethys Sea were compressed, folded, and uplifted, producing a very high and geologically young mountain system. This continuing plate movement also explains the region’s earthquakes and ongoing uplift. They are not volcanic mountains because their main formation was not caused by lava accumulation; they are not residual hills shaped mainly by long erosion, and sand dunes are wind-deposited features. Therefore, option B correctly identifies the geological type of the Himalayas.

Correct answer: C. North-east to south-west

The correct answer is north-east to south-west. The Aravalli Range extends from the Delhi region through parts of Haryana and Rajasthan toward Gujarat, giving it a general north-eastern to south-western orientation. It is one of the oldest fold mountain systems in India and has been greatly worn down by prolonged erosion. The word “generally” matters because the range is not a perfectly straight line, but its overall alignment is clearly represented by option C. An east-west or north-south line does not describe its broad course, and “south to east” is not the accepted orientation. Therefore, option C is correct.

Correct answer: D. Western Ghats

Anamudi, also written as Anamala or Anai Mudi, is a major peak located in Kerala in southern India. It belongs to the Western Ghats, the mountain system extending along the western side of peninsular India. It is commonly identified as the highest peak of the Western Ghats and one of the highest peaks in India outside the Himalayan region. Hence option D is correct. The Aravalli range lies mainly in northwestern India, the Shiwaliks form the outer foothills of the Himalayas, and the Vindhyas extend across central India. None of these mountain regions contains Anamudi. The peak’s location in Kerala and its association with the Western Ghats provide the geographical basis for the answer, rather than merely its being a southern Indian peak.

Correct answer: A. North-eastern India

The correct answer is north-eastern India. The Purvanchal Hills are the eastern continuation of the Himalayan mountain system and include ranges such as the Patkai, Naga, Manipur, and Mizo Hills. They curve around the north-eastern edge of the Indian subcontinent and help form the physical setting of several north-eastern states. Western Rajasthan is dominated by the Thar Desert and the Aravalli region, Kachchh is a semi-arid area in Gujarat, and the Malabar Coast is a coastal plain beside the Western Ghats. These landforms do not belong to Purvanchal. Hence, option A is correct.

Correct answer: B. Nagaland

The correct answer is option B, Nagaland. The Naga Hills are located in northeastern India and are chiefly associated with Nagaland, a state whose name reflects its historical connection with the Naga people. In physical geography, these hills are discussed as part of the Purvanchal, or northeastern, hill system, which continues eastward from the Himalayan region toward Myanmar. To eliminate the other choices, Rajasthan and Gujarat are western Indian states with different physical landscapes, while Haryana lies in northern India near the Indo-Gangetic Plain. None of these states is the principal geographical association of the Naga Hills. Therefore, the location and regional classification both support Nagaland as the unambiguous answer.

Correct answer: A. Mizoram

The name Mizo Hills refers to the hill region that occupies much of Mizoram in north-eastern India. The region is part of the eastern extension of the Himalayan mountain system, often discussed with the Purvanchal hills. The name of the hills is directly connected with the Mizo people and the state of Mizoram.

Consequently, option A, Mizoram, is correct. Punjab and Bihar are in northern plains, Goa is a small coastal state in western India, and none contains the Mizo Hills. The question asks for the state associated with the hills, not for a nearby mountain range or a broader physical division. The supplied answer is clear and accurate.

Correct answer: B. Purvanchal region

Option B, the Purvanchal region, is correct. The Patkai Hills are among the northeastern hills of India and are commonly classified as part of the Purvanchal, also called the Eastern Hills. This system represents the eastward extension of the Himalayan ranges and includes several ranges near the India–Myanmar boundary. The classification depends on both location and geological continuity: the Patkai Hills are in the Northeast and belong to the hill belt that bends southward from the eastern Himalayas. The Southern Plateau is a separate peninsular physiographic division, the Western Coast is a coastal lowland, and the Thar Desert is a dry region in northwestern India. Thus none of those alternatives fits the Patkai Hills, making the Purvanchal region the precise answer.

Correct answer: A. Himalayas

Option A, the Himalayas, is correct because this great mountain system strongly controls the climate of the Indian subcontinent. Its high, continuous ranges act as a barrier to extremely cold continental winds coming from Central Asia during winter. During the summer monsoon, the mountains also force moisture-laden winds to rise. Rising air cools, condenses, and produces rainfall, especially on windward slopes. The Himalayas therefore help shape the monsoon regime and protect the northern plains from the full force of cold continental air. Lakshadweep, a sea beach, and desert dunes can affect local weather or regional conditions, but they do not exert a comparable influence on the climate of India as a whole. The governing concept is the climatic role of relief, so option A is the only suitable answer.

Correct answer: B. South-west monsoon

The Western Ghats receive heavy rainfall mainly from the south-west monsoon, especially its Arabian Sea branch. These winds travel from the Arabian Sea toward the west coast of India and carry a large amount of moisture. When they meet the steep western slopes of the Western Ghats, the air is forced to rise. As the rising air cools, water vapour condenses and produces heavy orographic rainfall on the windward side.

Option B is correct because it identifies the moisture-bearing monsoon responsible for this rainfall. The north-east monsoon affects parts of southeastern India, but it is not the main cause of heavy rain on the western slopes of the Western Ghats. Local hot winds and cold waves are weather conditions, not the principal seasonal source of this widespread rain. The mountain barrier explains why rainfall is especially high on the western side.

Correct answer: C. Volcanic lava flows

Option C, volcanic lava flows, is correct. The Deccan Trap is a vast volcanic formation covering a large part of peninsular India. It developed when repeated and very extensive eruptions released basaltic lava that spread across the land in successive sheets. As each flow cooled and hardened, it formed a layer of dark basaltic rock. Over a long period, weathering and erosion exposed the edges of these stacked layers, producing the characteristic step-like or terraced topography. The word “trap” is associated with a term meaning stair or step. Sea corals form marine structures, river flood plains are deposited by flowing water, and glacial lakes are formed by ice-related processes; none explains the basalt layers of the Deccan Trap. Therefore option C is unambiguous.

Correct answer: D. Deccan Plateau

The Karnataka Plateau is a part of the Deccan Plateau in Peninsular India. It is an elevated inland region mainly made of ancient hard rocks and lies south of the central parts of the Deccan. The name Karnataka Plateau refers to the portion associated with Karnataka and nearby areas, while Deccan Plateau is the larger geographical region containing it.

Option D is correct because it gives the broader plateau region. The Ganga Plain and Brahmaputra Plain are low-lying alluvial plains formed mainly by river deposits, not elevated rocky plateaus. The Thar Desert is a dry sandy region in north-western India and is also not the landform of which the Karnataka Plateau is a part. Recognising the relationship between a smaller regional unit and a larger physiographic division leads directly to the answer.

Correct answer: A. Deccan Plateau

Option A, the Deccan Plateau, is correct. The Telangana Plateau is a regional part of the broad Deccan Plateau in peninsular India. Telangana lies on the southern Indian upland, where the surface is made up of extensive plateau areas, ancient crystalline rocks, and river valleys. In school geography, its physical setting is therefore studied within the Deccan Plateau rather than as an independent major physiographic division. The Meghalaya Plateau lies in northeastern India and is separated from the Deccan by the Gangetic and coastal regions. The Malwa Plateau is mainly in central-western India, while the Ladakh Plateau belongs to the high-altitude Trans-Himalayan region. Their locations and geological settings are different. Identifying Telangana as a peninsular state and southern upland leads directly to option A.

Correct answer: B. Trans-Himalaya

Ladakh belongs to the Trans-Himalayan region, which lies north of the main Himalayan ranges. This region has very high, dry plateaus, deep valleys, and rugged mountains. The Karakoram and Ladakh ranges are important parts of its physical setting. Its cold desert landscape is different from the lower and wetter mountain environments farther south.

Therefore option B, Trans-Himalaya, is correct. The Eastern Ghats are old hills along the east coast, while the Aravalli and Vindhya ranges lie much farther south and are not the larger mountain region associated with Ladakh. The classification in the question is a physical-geography relationship, and the supplied answer matches it.

Correct answer: C. Trans-Himalaya

Option C, Trans-Himalaya, is correct. The Trans-Himalaya consists of high mountain ranges situated beyond or generally north of the main Himalayan system, close to the Tibetan Plateau. The Kailash Range belongs to this broader high-altitude region and is associated with the Tibetan landscape, where the climate is cold, dry, and strongly influenced by elevation. The Outer Himalaya, or Shiwalik range, is the southernmost and comparatively lower Himalayan belt. The Middle or Lesser Himalaya lies between the Shiwaliks and the higher Himalayan ranges, so neither is the best classification for Kailash. The Eastern Ghats are a separate range in peninsular India and have no Himalayan connection. Its position beyond the main Himalayan chain and its Tibetan highland setting make Trans-Himalaya the appropriate answer.

Correct answer: D. Peninsular India

The correct answer is Peninsular India because this region contains the broad Deccan Plateau and several associated plateau divisions, including the Maharashtra, Karnataka and Telangana plateaus. Together, these form the most extensive plateau region of the country. A plateau is an elevated area with a comparatively level or gently undulating surface. The Northern Plains are mainly depositional alluvial lowlands, not a plateau region. The Sundarbans is a deltaic mangrove area, while the Rann of Kachchh is a seasonal salt-marsh region. Therefore, the location and physical structure of the Deccan and related plateaus make option D the only suitable answer.

Correct answer: A. Collision of plates

The Himalayas were formed mainly through the convergence and collision of the Indian Plate with the Eurasian Plate. As the Indian Plate moved northward, its continental crust pressed against the Eurasian continental crust. Because continental crust is relatively buoyant, it did not simply sink; instead, the sediments and rocks were compressed, folded and uplifted, producing a young fold mountain system. Sea waves, river deposition and sandstorms can shape or modify landforms, but they cannot account for the enormous height, length and folded structure of the Himalayas. Thus, plate collision is the governing geological process, making option A correct.

Correct answer: A. Himalayas and Deccan Plateau

Option A correctly pairs the Himalayas, a mountain system, with the Deccan Plateau, an elevated plateau region. Mountains are generally high, steeply rising landforms with considerable relief, whereas plateaus are elevated surfaces that are relatively level or gently rolling. The Ganga and Yamuna are rivers, so option B does not provide either required landform. Chilika and Wular are lakes, making option C incorrect. The Thar is a desert and the Sundarbans is a deltaic mangrove region, so option D also fails to give a mountain-and-plateau pair. The physical-geography categories therefore make A unambiguous.

Correct answer: A. Jharkhand

The Rajmahal Hills are mainly located in Jharkhand, particularly in the northeastern part of the state near the Rajmahal area and the Ganga valley. They form an important hill feature of eastern India and are also associated with the geological history of the Rajmahal volcanic province. Kerala contains portions of the Western Ghats, Punjab is largely associated with the northern plains and foothills, and Goa lies on the western coastal side near the Western Ghats. None of those alternatives is the principal state linked with the Rajmahal Hills. Therefore, the regional location of this hill system makes option A correct.

Correct answer: B. South India

The Cardamom Hills are situated in southern India, mainly along the southern Western Ghats in and around Kerala and the adjoining Tamil Nadu region. They are named after cardamom cultivation, although the area also supports other plantation crops and forests. Their position in the Western Ghats places them far from the Himalayan region of North India. Western Rajasthan is dominated by arid desert landscapes, while the Ganga Plain is a broad depositional plain formed largely by river sediments. Neither has the location or relief associated with the Cardamom Hills. Therefore, the broad regional classification clearly supports option B.

Correct answer: A. Maharashtra Plateau

The Maharashtra Plateau is an important northern and northwestern section of the Deccan Plateau. It is formed largely from extensive basaltic lava flows associated with the Deccan volcanic province, and weathering of these rocks has contributed to the development of black cotton soil in many areas. The Meghalaya Plateau and Shillong Plateau belong to the northeastern highlands, not to the Maharashtra part of the Deccan. The Ladakh Plateau is a high-altitude plateau in the Trans-Himalayan region and has a very different geological and climatic setting. Consequently, the regional identity and physical characteristics both support option A.

Correct answer: C. Karnataka

The Baba Budan Hills are located in Karnataka and form part of the hill ranges of the central Western Ghats. They are historically and geographically associated with the Chikkamagaluru region, which is well known for coffee cultivation. Their location in the Western Ghats gives them a rugged, elevated landscape with favourable conditions for plantation agriculture. Assam lies in northeastern India, Gujarat is associated with the western peninsula and arid or semi-arid regions, and Haryana is mainly part of the northern plains with nearby low hills in limited areas. None of these alternatives is the principal state linked with Baba Budan Hills. Hence, option C is correct.

Correct answer: A. North

The governing concept is the location of India's major physical divisions. The Himalayas form a high mountain system along the northern edge of the Indian subcontinent, extending broadly from the northwest toward the northeast. They include ranges such as the Greater Himalaya, Lesser Himalaya and Shiwalik, and they act as a major natural barrier and source region for several rivers. Therefore option A, north, is correct. Option B is incorrect because peninsular uplands and coastal ranges dominate much of southern India. Options C and D are also unsuitable: the Himalayas are not a western coastal or island landform. The question asks for their broad Indian direction, not every local bend in their alignment.
