Mountains and Plateaus of India

The Chota Nagpur Plateau is an important mineral-rich region of India. Its industrial development is strongly supported by deposits of coal, iron ore, mica, bauxite, and other minerals. Coal supplies fuel and energy, while iron ore and related minerals provide raw material for iron and steel, engineering, and manufacturing industries. The governing geographical principle is that industries often develop where essential raw materials and energy sources are available, reducing cost and encouraging related activities. Therefore option C is correct. Sea ports are not the plateau’s main natural advantage, and glaciers or coral islands are not characteristic features of this region. Transport, labour, investment, and markets also matter, but the question asks for the chief natural basis.

The Western Ghats form a long mountain chain along the western side of Peninsular India, but the chain is interrupted by important gaps. The Palghat Gap is a broad natural opening between the Nilgiri Hills and the Anaimalai Hills. Since it is lower than the surrounding mountains, it provides a passage between the interior plateau and the coastal region, especially between Kerala and Tamil Nadu. It has therefore influenced transport, settlement, communication, and local climatic conditions. Option A is correct. It is not a Himalayan summit, an Aravalli mineral belt, or a delta of the Ganga Plain. Those descriptions refer to different geographical features and regions.

The Meghalaya Plateau is not a Himalayan fold, coastal plain, or sandy part of the Thar Desert. It is regarded as a detached extension of the ancient Peninsular Plateau in north-eastern India. Geological and geographical descriptions commonly treat it as a separate block because it is isolated from the main peninsular plateau by surrounding lowlands and river valleys.

The plateau includes the Garo, Khasi, and Jaintia Hills. Although it lies in the north-east, its old plateau character connects it with the Peninsular Plateau rather than with the young folded Himalayas. Thus option B is correct. The word isolated means geographically separated or detached; it does not mean unrelated in geological origin.

Option C is correct because the Godavari, Krishna, and Cauvery flow eastward across the Deccan region and cut through the discontinuous Eastern Ghats before reaching the Bay of Bengal. The Eastern Ghats are not a continuous wall like a perfectly unbroken range; large rivers have created gaps and valleys across them. The Indus, Jhelum, and Chenab belong mainly to the north-western river system, while Luni, Mahi, and Sabarmati are associated largely with western or north-western drainage. Narmada and Tapi flow westward through rift valleys, so option D is also incorrect.

Option A is correct because the Deccan Plateau has a general gradient toward the east and south-east. Rivers such as the Godavari, Krishna, and Cauvery follow this broad slope and drain into the Bay of Bengal, often forming deltas near their mouths. The rule is general rather than absolute: the Narmada and Tapi flow westward through structural rift valleys, showing that local geology can alter drainage direction. Option B reverses the main regional slope, C is false because many Deccan rivers rise within or near the peninsula, and D ignores the clear relief that guides river flow.

Option C is correct because the Purvanchal Hills represent the north-eastern, bent continuation of the Himalayan mountain system. After the Himalaya turns sharply near the eastern end, its ranges continue through the Patkai, Naga, Manipur, and Mizo hills. These hills form an important arc along the north-eastern edge of the Indian subcontinent and help shape regional drainage, climate, and political boundaries. They are not part of the Western Ghats, the Aravalli system, or the basaltic Deccan Trap. The phrase “north-eastern bend” identifies both their location and their structural connection with the Himalaya.

Option D is correct because Ladakh combines the defining conditions of a desert with a very cold high-altitude environment. The plateau lies in the rain-shadow region north of the main Himalayan ranges, so the monsoon brings little precipitation. Its great elevation produces low temperatures, long severe winters, and a short growing season. Sparse vegetation and limited surface water are further consequences of this dryness and cold. It is therefore described as a Trans-Himalayan cold desert. Dense tropical forests, high marine humidity, and permanently hot temperatures are all inconsistent with Ladakh’s high, dry continental setting.

Option A is correct because both Malwa and Bundelkhand are plateau regions of central India and form part of the broader northern section of the Peninsular Plateau. Malwa lies mainly in the west-central part of the region, while Bundelkhand extends across parts of Uttar Pradesh and Madhya Pradesh. Their relief, rock structure, drainage, and location distinguish them from coastal plains and island coral formations. The Kashmir Valley is an intermontane valley associated with the Himalaya, not a central Indian plateau. Therefore the broad physiographic classification in option A is the most accurate.

Option B is correct because the Amarkantak region is an important source area and watershed in central India. The Narmada rises near Amarkantak and flows westward, while the Son begins in the same broader highland and flows eastward toward the Ganga system. This contrast makes the plateau a significant water divide: drainage is directed into different river basins from nearby elevated ground. It is not a sea mouth, coral island, or sandy delta. Although the question mentions rivers, its central idea is the physical role of a plateau as an elevated source and watershed region.

The governing concept is the regional division of the Peninsular mountain system. Satpura is a prominent range of central India, and Maikal and Mahadeo are recognised as associated sub-ranges or hill units within this broader system. Therefore, option A is correct. The other choices describe entirely different landforms: eastern coastal plains are low-lying depositional areas beside the Bay of Bengal, Meghalaya hills belong to the northeastern hill region, and coral islands are built by marine organisms rather than being parts of a continental mountain range. Remembering Maikal and Mahadeo with Satpura helps distinguish central Indian relief from the Himalayas, coastal plains and island formations.

The governing concept is the regional subdivision of the Peninsular Plateau. The Deccan Plateau is a large triangular upland south of the Narmada, and its broad surface includes several regional plateau units. The Karnataka Plateau and Telangana Plateau are two such regional parts, so option C is the most accurate classification. They are not Himalayan plateaus because they lie in southern Peninsular India and have an ancient geological foundation. Coastal lagoons are shallow water bodies separated partly from the sea by barriers, while the northeastern islands are insular landforms. The wording “broad classification” asks for the larger physiographic unit, not merely the state location.

The governing concept is the regional division of the Western Ghats, also called the Sahyadri range in many parts of India. Anamudi is a major peak of the southern Western Ghats in Kerala, and Agasthyamalai is a prominent hill mass near the Kerala–Tamil Nadu border. Thus option D correctly places both features in the southern Western Ghats. The Purvanchal Hills belong to the northeastern extension of the Himalayan system, the Aravalli is an older range of northwestern India, and the Vindhya region lies mainly in central India. Their locations, relief and regional associations differ, so none of those alternatives fits both names.

The governing concept is the distinction between the Trans-Himalayan mountain region and the Peninsular Plateau. Karakoram and Ladakh are high mountain ranges situated north of the main Himalayan chain and are commonly studied under the Trans-Himalayan system. The Deccan Plateau, in contrast, is an ancient elevated tableland of southern Peninsular India. Hence option A correctly identifies the basis of distinction. Black-soil cotton regions describe an agricultural and soil association, not the physical category of these ranges. Eastern coastal plains are lowlands beside the sea, and coral islands are marine formations. Relief, location and geological setting—not simply land use—separate the Karakoram and Ladakh ranges from the Deccan Plateau.

The governing concept is the contrasting structure of India’s Eastern and Western Ghats. The Eastern Ghats are discontinuous because major rivers such as the Mahanadi, Godavari, Krishna and Kaveri cut across them, separating the hills into sections. Mahendragiri in Odisha and the Shevaroy Hills in Tamil Nadu are examples associated with this Eastern Ghats system. Therefore, option C is correct. The Western Ghats are generally more continuous and form a stronger escarpment along the western edge of the Deccan Plateau. The Aravalli is a separate ancient range, while the Karakoram belongs to the Trans-Himalayan region. The clue “discontinuous” is especially important for identifying the Eastern Ghats.

The governing concept is the regional grouping of central Indian relief features. The Kaimur Range is generally treated as an eastern extension or component of the Vindhyan system, stretching across parts of central and eastern India. Consequently, option A, the Vindhyan region, is correct. The Nilgiri region belongs to the southern Western Ghats, the Karakoram region lies in the high Trans-Himalayan north, and Lakshadweep is a group of coral islands in the Arabian Sea. These alternatives represent different mountain or island environments and cannot classify Kaimur. Linking Kaimur with the Vindhyan highlands is useful for understanding the plateau margins, escarpments and ranges of central India.

The governing concept is the regional geography of the Peninsular Plateau. Singhbhum Plateau is mainly in Jharkhand, while the Chota Nagpur Plateau is the larger plateau system of eastern India that includes or is closely associated with the Singhbhum area. This region is built largely of ancient crystalline rocks and is well known for iron ore, coal, copper, mica and other minerals. Therefore, option A correctly identifies their shared physical and economic setting. Option B is wrong because neither is a coastal marsh; option C is wrong because they are not glacial plains; and option D describes coral landforms, which are unrelated to these inland plateaus.

The governing concept is the geological and physiographic structure of the Peninsular Plateau. The Dharwar region of Karnataka contains some of India’s oldest rocks, including ancient crystalline formations that have been deeply weathered and uplifted over geological time. It is therefore studied as an old plateau and rocky shield area of southern India, not as a young depositional landform. Option A is correct because it identifies both its location and its ancient plateau character. Option B is incorrect because a Ganga delta is a recent alluvial coastal feature. Option C refers to the Himalayan mountain system, and option D refers to coral islands, neither of which matches Dharwar geology.

The governing concept is the location of hill ranges within India’s major plateau divisions. The Balaghat Range lies in the central-southern part of the Peninsular Plateau, particularly across areas associated with Maharashtra and adjoining Karnataka. It is therefore studied in connection with the Deccan Plateau. Option B is correct because the range forms part of the upland landscape of this broad basaltic and ancient plateau region. Option A is wrong because the Meghalaya Plateau is an isolated northeastern plateau. Option C belongs to the high-altitude Trans-Himalayan region, while option D is a valley enclosed by Himalayan ranges. Their locations and geological settings are different.

The governing concept is the subdivision of the Central Indian highlands. The Bhander Plateau is a plateau unit associated with the Vindhyan range and the north-central part of the Peninsular Plateau. Its surface has developed on old sedimentary rocks and is linked geographically with the Bundelkhand and surrounding central Indian uplands. Hence option C is correct: it identifies Bhander as part of the Vindhyan plateau region. Option A describes a mountain peak, not a plateau. Option B is a narrow route through the Western Ghats, while option D refers vaguely to a humid hill area in the northeast; neither represents the physical identity of Bhander Plateau.

The governing concept is the division of the Himalayan system into the main Himalaya and the ranges lying beyond it. The Zanskar Range and the Kailash Range are generally grouped with the Trans-Himalaya, the high mountain region north of the main Himalayan axis. These ranges are associated with Ladakh and the Tibetan plateau-margin environment and are characterized by very high, rugged, cold and dry terrain. Therefore option C is correct. Option A refers to the low outer foothills, not the high ranges beyond the Himalaya. Options B and D are separate peninsular hill systems in southern and eastern India, so they cannot describe Zanskar or Kailash.

The governing concept is the location of Indian hill stations and ranges. Yercaud is a hill station in Salem district of Tamil Nadu, situated in the Shevaroy Hills. These hills form part of the elevated Eastern Ghats landscape and are known for a pleasant hill climate, coffee cultivation and forested slopes. Thus option A is correct because it gives the specific hill range with which Yercaud is geographically associated. Option B refers to the northeastern hills, option C to a central Indian range, and option D to the Meghalaya region. Although all are genuine Indian hill systems, none is the location of Yercaud.

The governing concept is the regional geography of the Western Ghats and Karnataka’s hill landscapes. Kodagu, also called Coorg, lies in the Western Ghats of Karnataka, while the Baba Budan Hills are another important hill group in Karnataka’s Western Ghats. Both areas have high rainfall, forested slopes and suitable upland conditions for plantation agriculture, especially coffee cultivation. Therefore option A correctly states their common regional relationship. Option B belongs to the dry northwestern hill system of Rajasthan, option C to the northeastern hills, and option D to a broad alluvial plain. Those settings differ sharply in location, relief and climate.

The governing concept is the identification of major mountain ranges and their prominent peaks. Godwin Austen is the commonly used name associated with K2, one of the world’s highest mountains, located in the Karakoram range. In school-level Indian geography, this name is therefore linked with the Karakoram mountain region in the northwestern highlands. Option A is correct. The Aravalli is an old, much lower and highly eroded range of western India; the Eastern Ghats are discontinuous hills along the east coast; and the Satpura is a central Indian range. None of those three contains the peak identified as Godwin Austen.

The governing concept is the regional subdivision of the Central Indian highlands. The Baghelkhand Plateau and the Rewa Plateau are located in and around the Vindhyan uplands of central India, mainly across parts of Madhya Pradesh and adjoining regions. They form elevated inland plateau surfaces rather than coastal, marine or glacial landscapes. Consequently, option A is correct because it places both in the plateau part of Central India. Option B describes a low coastal environment of Kerala, option C refers to coral and marine islands, and option D describes a high Himalayan glacial setting. Their landforms, climate and geological context are all different from those of Baghelkhand and Rewa.

The governing concept is the location of hill ranges within the eastern Indian plateau system. The Rajmahal Hills are situated in present-day Jharkhand, near the eastern margin of the Chota Nagpur Plateau and close to the Ganga plain. They are therefore associated with an inland plateau-hill environment of eastern India. Option A is correct because it identifies both the state and the broad physical setting. Option B refers to Rajasthan’s arid sandy landscapes, option C to a coastal environment in Goa, and option D to the cold desert of Ladakh. Those regions differ from Rajmahal in location, relief, climate and geological setting.
