Mountains and Plateaus of India

Correct answer: C. Regional parts of the Deccan Plateau

The governing concept is the subdivision of the Peninsular Plateau according to location and geological structure. The Karnataka Plateau occupies much of the interior of Karnataka, while the Telangana Plateau lies mainly in the interior Deccan region. Both are elevated regional units of the larger Deccan Plateau and are separated from coastal lowlands by the Western and Eastern Ghats or their associated uplands. Therefore, option C is correct. Himalayan plateaus belong to a different young mountain environment. Coastal lagoons are water bodies separated from the sea by barriers, and northeastern islands are not plateau subdivisions. Their physical form and location make options A, B and D unsuitable.

Correct answer: D. Southern Western Ghats

The governing concept is the regional identification of important peaks and hill groups in Peninsular India. Anamudi is the highest peak of the Western Ghats and lies in Kerala, while Agasthyamalai is a prominent mountain area in the southern Western Ghats near the Kerala–Tamil Nadu region. Their locations and physical setting place both within the southern Western Ghats. Thus option D is correct. The Purvanchal Hills belong to northeastern India, the Aravalli Range lies mainly in western India, and the Vindhya system is a central Indian highland. These alternatives are geographically separate and do not explain the relationship between Anamudi and Agasthyamalai.

Correct answer: A. Himalayan peaks

The governing concept is the physical classification of prominent Indian relief features. Nanda Devi is a major Himalayan peak in Uttarakhand, while Kanchenjunga is a very high Himalayan peak associated with the Sikkim–Nepal region. Although they are located in different parts of the Himalayan arc, both are mountain summits rather than soils, lagoons or passes. Therefore, option A is correct. Deccan soils are a soil category of Peninsular India, not peaks. Eastern coastal lagoons are shallow water bodies along the coast, and Aravalli passes are routes through an older range in western India. Their landform types and locations clearly distinguish these distractors from Nanda Devi and Kanchenjunga.

Correct answer: C. Sahyadri region of Maharashtra

The governing concept is the regional naming of the Western Ghats. Mahabaleshwar, Lonavala and Khandala are well-known hill stations and highland locations in Maharashtra, situated along or associated with the Sahyadri section of the Western Ghats. Consequently, option C is correct. Sahyadri is a widely used regional name for the Western Ghats in Maharashtra and nearby areas. Sikkim Himalaya belongs to the northeastern Himalayan arc, the Aravalli region is in western India and has a different geological setting, and the Barail Hills are in northeastern India. Their locations do not match this group of Maharashtra hill stations.

Correct answer: D. Karnataka

The governing concept is the connection between physical regions and agricultural specialization. The Baba Budan Hills are part of the Karnataka section of the Western Ghats, where a suitable elevation, warm climate, seasonal rainfall and well-drained slopes support coffee cultivation. Karnataka is one of India’s leading coffee-producing states, and the hills are historically associated with the spread of coffee cultivation in the region. Therefore, option D is correct. Rajasthan is dominated by arid and semi-arid conditions, Bihar is mainly associated with alluvial plains, and Haryana has broad plains with different agricultural characteristics. These states do not fit the specific hill-and-coffee association in the question.

Correct answer: A. Eastern Ghats

Mahendragiri and Shevaroy are hill groups belonging to the Eastern Ghats, the discontinuous mountain system along much of eastern peninsular India. The Eastern Ghats are not one unbroken wall because rivers such as the Mahanadi, Godavari, Krishna and Kaveri have cut across them. Shevaroy Hills are in Tamil Nadu, while Mahendragiri is associated with the Odisha-Andhra region, both fitting the Eastern Ghats setting. The Western Ghats form a more continuous escarpment on the western side of the peninsula, so option B is unsuitable. Aravalli is an older range of northwestern India, and Karakoram is a high Trans-Himalayan range. Therefore, option A is correct.

Correct answer: B. Both are linked with mineral-rich eastern India

The Singhbhum Plateau and the Chota Nagpur region are linked with the mineral-rich plateau belt of eastern India, especially Jharkhand. This ancient plateau contains important deposits of iron ore, coal, copper, bauxite and other minerals, which support mining, metallurgy and heavy industries. Singhbhum is a major mineral-producing area within or adjoining the broader Chota Nagpur Plateau, so the relation in option B is geographical as well as economic. Coastal lagoons are low-lying water bodies separated from the sea, not plateau units. Glacial plains are formed by ice and are not the defining landform here, while coral islands are marine formations. Hence option B is the only suitable answer.

Correct answer: C. Vindhyan region

The Kaimur Range and Bhander Plateau are important components of the Vindhyan physical region in central India. The Kaimur Range forms an eastern extension or escarpment of the Vindhya system, while the Bhander Plateau is a plateau division associated with the Vindhyan landscape. Their rocks, relief and location distinguish them from the southern hill systems. The Nilgiri region belongs to the meeting zone of the Western and Eastern Ghats, so option A is incorrect. The Western Ghats lie along the western edge of the Deccan, and the Karakoram is a high mountain system in the Trans-Himalaya, neither matching these central Indian landforms. Therefore, option C is correct.

Correct answer: D. Trans-Himalayan region

The Zanskar and Kailash ranges are associated with the Trans-Himalayan region, which lies beyond the main Himalayan ranges toward the Tibetan Plateau. These ranges are characterized by very high elevations, rugged relief, cold-arid conditions and extensive mountain valleys. Zanskar is prominent in the high mountain landscape of Ladakh, while the Kailash range is associated with the Tibetan sector of the wider Trans-Himalayan system. The eastern coastal plain is a low, depositional strip beside the Bay of Bengal; the southern Western Ghats are peninsular hills; and the Deccan Trap is a volcanic plateau formed by extensive basaltic lava flows. Thus, only option D gives the correct regional relationship.

Correct answer: A. Shevaroy Hills

Yercaud is a hill station situated in the Shevaroy Hills of Tamil Nadu, which form part of the Eastern Ghats. The area is known for its elevated plateau-like terrain, pleasant hill climate, forests and plantations, including coffee. This place-name association is the key to the question: Yercaud points to Shevaroy Hills, so option A is correct. Naga Hills are in the northeastern part of India, mainly associated with Nagaland and adjoining areas. Satpura is a separate central Indian mountain system, while Khasi Hills are located in Meghalaya. Although all four options are hill regions, their locations differ substantially; only Shevaroy Hills has the direct geographical connection with Yercaud.

Correct answer: B. Western Ghats region of Karnataka

Kodagu and Kudremukh are both associated with the Western Ghats of Karnataka. Kodagu, also called Coorg, is a hilly district on the western side of Karnataka and is well known for coffee plantations, forests and high rainfall. Kudremukh is a mountainous area in the central part of the Karnataka Western Ghats, noted for grasslands, forests and rugged highland relief. Their shared regional identity makes option B correct. The Aravalli region belongs mainly to northwestern India, the Barail ranges are associated with the northeastern hill system, and the Ganga Plain is a broad depositional plain rather than a mountain region. Thus, the common geographical relation is not merely that both are elevated places; both specifically belong to Karnataka's Western Ghats landscape.

Correct answer: C. Karakoram

Godwin Austen is the name historically associated with K2, one of the world's highest mountains, which stands in the Karakoram range. In Indian geography questions, the essential link is Godwin Austen or K2 equals Karakoram. The Karakoram is a high, heavily glaciated mountain system in the Trans-Himalayan region, north of the main Himalayan ranges. Satpura is a much lower, older range of central India; the Eastern Ghats are discontinuous hills along the eastern peninsula; and the Aravalli is an ancient range in northwestern India. None of those systems contains K2. Therefore, option C is correct. The answer depends on recognizing the standard peak-to-range association rather than confusing the mountain with the broader Himalaya.

Correct answer: D. Plateau part of Central India

Baghelkhand and the Rewa Plateau belong to the plateau country of central India and are associated with the Vindhyan highland system. Rewa is in northeastern Madhya Pradesh, while Baghelkhand covers the adjoining eastern Madhya Pradesh region and nearby areas. Their relief is therefore part of the central Indian plateau landscape, making option D correct. The coastal part of Kerala is a low coastal plain, Lakshadweep is a group of coral islands in the Arabian Sea, and the glacial part of Sikkim belongs to the high Himalaya. These alternatives represent coastal, marine or Himalayan environments, not the peninsular plateau. The key reasoning is to connect both named plateaus with central India's Vindhyan regional geography.

Correct answer: A. With the plateau-hill region of Jharkhand

The Rajmahal Hills are located in eastern India and are associated with the plateau-and-hill landscape of Jharkhand, close to the eastern part of the Chota Nagpur region. They form a distinct upland area and are also known for the Rajmahal volcanic rocks produced by ancient basaltic lava flows. This location and geological setting make option A the correct relation. The Thar is a sandy desert and lies far to the west; Goa's coastal plain is a low strip beside the Arabian Sea; and Ladakh is a cold-arid highland in the Trans-Himalaya. None of those environments matches the Rajmahal Hills. The question therefore tests regional placement: eastern Jharkhand plateau-hill geography, not desert, coast or high Himalayan terrain.

Correct answer: B. Ghats region of South India

The Nilgiri, Palani and Cardamom Hills are southern Indian hill groups associated with the Ghats region, especially the Western Ghats and their southern extensions. The Nilgiris form an important highland junction near the meeting area of the Eastern and Western Ghats. The Palani and Cardamom Hills continue the elevated terrain farther south in the Western Ghats system. Thus, option B provides the broad regional identity shared by all three. The Ganga Delta is a low alluvial and tidal depositional region, the Thar is a desert, and Lakshadweep consists of coral islands in the Arabian Sea. Those features cannot explain the location or relief of these highland groups. Therefore, the correct larger region is the Ghats region of South India.

Correct answer: C. Western Ghats are more continuous and Eastern Ghats are more broken

The governing concept is the comparison of India’s two major peninsular mountain edges. The Western Ghats run more continuously along the western side of the Deccan Plateau, although they are interrupted at important passes and gaps. The Eastern Ghats are older, lower in many sections, and considerably more discontinuous because major rivers such as the Mahanadi, Godavari, Krishna, and Kaveri have cut across them. Therefore, option C gives the accurate comparison. Option A is wrong because the Himalayas are much higher; option B confuses landforms with islands; and option D places the Western Ghats in the wrong region, since they lie beside the western coastal plain.

Correct answer: D. Rivers get water from snow and rainfall

The governing concept is the difference between perennial and seasonal rivers. Himalayan rivers receive water from more than one continuing source: monsoon rainfall feeds them during the rainy season, while snow and glacier melt continue to supply water during warmer months. This combined supply helps rivers such as the Ganga, Yamuna, and Brahmaputra flow through much of the year, though their discharge still rises and falls seasonally. Thus option D is correct. Option A is meaningless because blocking water would not create a river supply; option B describes neither the main source nor the process; and option C concerns coral formation, which has no connection with Himalayan river flow.

Correct answer: A. Major ranges of the mountain-plateau region

The governing concept is the arrangement of relief features in Peninsular or Central India. The Vindhya and Satpura ranges are important upland ranges of the central Indian mountain-and-plateau region. The Narmada Valley lies between them in a broad structural depression, while the Tapi flows south of the Satpura range. These relationships show why the two ranges are studied together as major central Indian relief features. Therefore option A is correct. Options B and C are marine features and do not describe inland ranges. Option D is also unsuitable because a delta is a depositional landform formed near a river mouth, whereas Vindhya and Satpura are elevated, rocky ranges.

Correct answer: B. High and continuous mountain wall

The governing concept is the orographic effect of a mountain barrier on moist monsoon winds. The Western Ghats stand close to the Arabian Sea and form a high, comparatively continuous wall. When moisture-laden southwest monsoon winds meet this barrier, they are forced to rise, cool, and condense, producing heavy orographic rainfall on the windward western slopes. The warm, wet conditions, varied altitude, and different habitats also support exceptional biodiversity. Hence option B is correct. A flat plain would not force air upward, distance from the sea would reduce access to moisture, and sand dunes do not create the elevation or rainfall mechanism described.

Correct answer: A. Himalayas are young fold mountains and Deccan is an ancient lava plateau

The governing concept is the geological origin of contrasting landforms. The Himalayas formed relatively recently in geological time through the collision of the Indian Plate with the Eurasian Plate, which compressed and folded sedimentary layers into young fold mountains. The Deccan Plateau is much older and is strongly associated with extensive basaltic lava flows from ancient volcanic activity, especially the Deccan Traps. Therefore option A correctly identifies both origins. The Himalayas are not a southern part of the Deccan, and the Deccan is not an outer Himalayan range. Option D is impossible because neither landform is simply a coral island group; both are large mainland physiographic regions.

Correct answer: B. Himalayas, Western Ghats, and Meghalaya Plateau

The governing concept is the regional arrangement of India’s major physiographic divisions. The Himalayas are the dominant mountain system of northern India. The Western Ghats are a major mountain edge along the western side of southern Peninsular India, and the Meghalaya Plateau is an important highland unit of north-eastern India. Thus option B provides one suitable physical unit for each of the three stated regions. Option A lists rivers or a lake rather than a north–south–north-east set of major relief units. Option C mixes a desert, a deltaic wetland, and a lake, while option D lists islands and a coastal region, not the requested mountain-and-plateau group.

Correct answer: D. Vindhya, Satpura, and Malwa-Bundelkhand region

The governing concept is the physiographic classification of Central India. The Vindhya and Satpura ranges are major upland and mountain systems of the Peninsular Plateau, while the Malwa and Bundelkhand areas represent adjoining plateau surfaces. Their combination therefore expresses the mixed mountain-plateau relief of the region. Option D is correct because all three names belong to the landform pattern of Central India. Option A lists islands and a desert-related region, not this relief system; option B lists rivers and a lake; and option C lists surrounding water bodies. Thus the answer follows geographical landform association rather than merely locating places on a map.

Correct answer: A. Nilgiri Hills

The governing concept is the identification of important hill ranges and peaks of India. Doddabetta is the highest peak of the Nilgiri Hills, and Mukurthi is another prominent peak in the same highland region of southern India. Therefore option A correctly associates both names with the Nilgiri Hills. The Aravalli range is an ancient system in north-western India, the Mishmi Hills lie in the north-east, and the Satpura range belongs mainly to central India. Those alternatives are genuine Indian landforms, but they are not the region containing these two peaks. The shared geographical location of Doddabetta and Mukurthi makes A unambiguous.

Correct answer: B. Maharashtra

The governing concept is the regional distribution of Peninsular mountain and plateau features. The Harishchandra range and the Ajanta Hills are located in Maharashtra and form part of the rugged upland landscape associated with the Deccan Plateau and the western Indian highlands. Hence option B is correct. Karnataka also contains important plateau and ghat landscapes, but these named hill groups are not its standard association. Meghalaya and Arunachal Pradesh belong to the north-eastern hill and plateau systems, which have different geological and geographical settings. The key reasoning is to match both named ranges with the state in which they occur, not simply with any state containing hills.

Correct answer: A. Mountain range of Assam and Nagaland region

The governing concept is the location of hill ranges in the physiography of North-east India. The Barail Range forms part of the folded hill systems around Assam and Nagaland and is commonly studied with the ranges and hills of the north-eastern region. Therefore option A is correct. Rajasthan's sandy landscapes belong to the north-western desert region, the Deccan lava plateau is a Peninsular feature, and Kerala's coastal plain is a lowland rather than a mountain range. These distractors represent different physiographic settings. Identifying the regional location of Barail, rather than confusing it with a plateau or coastal feature, leads directly to A.
