Mountains and Plateaus of India

Correct answer: A. Satpura

Option A is correct because both Dhupgarh and Pachmarhi are associated with the Satpura mountain region of Madhya Pradesh. Dhupgarh is regarded as the highest point of the Satpura Range, while Pachmarhi is a famous hill station located among the Satpura hills and is popularly called the Queen of Satpura. The region contains forested uplands, valleys and sandstone landscapes typical of central India. The Aravalli lies mainly in western India, the Eastern Ghats occur along the eastern side of the peninsula, and the Nilgiris are in the southern Western Ghats area. These locations do not correspond to Pachmarhi or Dhupgarh. Hence, the Satpura association makes A unambiguously correct.

Correct answer: A. Nilgiri Hills

The correct answer is the Nilgiri Hills. Ooty, also called Udhagamandalam, is a famous hill station situated in the Nilgiri district of Tamil Nadu, and Doddabetta is the highest peak of the Nilgiri Hills, rising to about 2,637 metres. The Nilgiris form an important highland junction in the southern Western Ghats region and are known for their cool climate, grasslands and shola vegetation. The Mishmi Hills are in Arunachal Pradesh, the Mizo Hills are in Mizoram, and the Rajmahal Hills are in Jharkhand. Since none of those regions contains both Ooty and Doddabetta, option A is the only geographically correct association.

Correct answer: A. Kodaikanal is a hill town associated with the Palani Hills

Option A is correct because Kodaikanal is a well-known hill town situated in the Palani Hills of Tamil Nadu. The Palani Hills are an eastern offshoot of the Western Ghats and form an important upland landscape in southern India. Their elevation gives Kodaikanal a cooler climate than the surrounding plains, while forests, grasslands and valleys contribute to its distinctive mountain environment. Kodaikanal is not a peak of the Aravalli Range. The Palani Hills are also not located in the Ganga Plain or the Thar Desert; those are separate northern alluvial and north-western arid regions. Thus, the location-based relationship stated in option A is accurate.

Correct answer: A. Sahyadri or Western Ghats

The correct answer is A, the Sahyadri or Western Ghats. Mahabaleshwar, Lonavala, and Khandala are well-known hill stations located in or closely associated with the Western Ghats of Maharashtra. Sahyadri is the regional name commonly used for the Western Ghats, especially in Maharashtra and Karnataka. These mountains run roughly parallel to the western coast and rise sharply from the coastal plain. Their relief also affects rainfall because they force moisture-bearing monsoon winds to rise. The Shiwalik Himalaya belongs to the Himalayan system in northern India, the Purvanchal Hills lie in the far northeast, and the Kachchh Plateau is an unrelated landform of Gujarat. Therefore, the group clearly identifies the Sahyadri-Western Ghats region.

Correct answer: A. Karnataka

The correct answer is A, Karnataka. The Baba Budan Hills and Kudremukh Hills are important highland areas of the Karnataka section of the Western Ghats. Baba Budan is famous in geographical and historical studies for its association with coffee cultivation, while Kudremukh is known for its rugged, green mountain landscape, iron-ore history, forests, and rich biodiversity. Their location in the Western Ghats explains the heavy rainfall, evergreen vegetation, and numerous streams found in the region. Bihar, Haryana, and Rajasthan do not contain these two well-known hill groups. The question is therefore solved by linking both names with Karnataka rather than by treating them as rivers, plateaus, or Himalayan features. Option A is the only option that correctly identifies their state.

Correct answer: A. Eastern Ghats

The correct answer is A, the Eastern Ghats. Mahendragiri is an important peak in the Eastern Ghats, and the Javadi Hills are also part of this discontinuous hill system in peninsular India. Unlike the relatively continuous Western Ghats, the Eastern Ghats are broken into separate ranges by major rivers such as the Mahanadi, Godavari, Krishna, and Kaveri. The Javadi Hills are located in northern Tamil Nadu, while Mahendragiri is associated with the eastern coastal highlands near Odisha and Andhra Pradesh. The Karakoram belongs to the trans-Himalayan region, the Aravalli is an ancient range of northwestern India, and the Western Ghats form a different escarpment along the west coast. Thus, both names point to option A.

Correct answer: A. Plateau-hill region of eastern India

The correct answer is A, the plateau-hill region of eastern India. The Rajmahal Hills and the Singhbhum region are important parts of the eastern Indian upland landscape, particularly in and around Jharkhand. Singhbhum is associated with the southern part of the Chota Nagpur Plateau, while the Rajmahal Hills form a distinct upland zone in the northeast of Jharkhand. These areas contain old rocks, dissected plateaus, hills, forests, and mineral-bearing formations. The western coastal plain is a narrow lowland beside the Arabian Sea, Lakshadweep is a coral-island region, and the Thar is an arid sandy plain of northwestern India. Since the question asks for the wider landform setting rather than a single state, option A is the most accurate and inclusive description.

Correct answer: A. Vindhyan region

The correct answer is A, the Vindhyan region. The Kaimur Range forms the eastern extension of the Vindhya system, and the Bhander Plateau is also treated as a related part of the Vindhyan highland landscape. These uplands occur in central India and are characterized by elevated plateaus, escarpments, sedimentary rocks, and deeply cut valleys in places. The Kaimur upland stretches across parts of states such as Uttar Pradesh, Bihar, Madhya Pradesh, and Jharkhand, while Bhander is associated with the central Indian plateau structure. The Nilgiri region belongs to the southern Western Ghats, the Karakoram is a trans-Himalayan mountain system, and the Western Ghats lie along the western peninsula. Therefore, the shared physical-region classification is the Vindhyan region.

Correct answer: A. Rainfall from the Arabian Sea branch of monsoon becomes high

The correct answer is A. The Western Ghats form a long, comparatively continuous escarpment close to India’s western coast. When the moisture-laden Arabian Sea branch of the southwest monsoon reaches this barrier, the air is forced to rise along the windward slopes. Rising air cools, condenses, and produces heavy orographic rainfall on the western side and nearby highlands. The Ghats therefore help create a wet west-facing zone, while some areas east of the range lie in a rain-shadow region. This process does not create Himalayan glaciers, place the Ganga Delta in South India, or locate the Thar Desert there. Thus, the continuity of the Western Ghats is directly associated with increased rainfall from the Arabian Sea branch.

Correct answer: A. It blocks cold winds and influences monsoon

The correct answer is A. The Himalayas form a very high mountain barrier along the northern edge of the Indian subcontinent. They reduce the direct entry of extremely cold continental winds from Central Asia into the plains, helping India maintain a comparatively warmer winter climate than it would otherwise have. The range also intercepts and guides moisture-bearing monsoon winds, encouraging rainfall over the northern plains and supporting the major river systems fed by snow and rainfall. The Himalayas do not separate India from the sea, convert every plateau into a desert, or eliminate the Western Ghats. Their importance is therefore both climatic and hydrological, with the blocking of cold winds and influence on monsoon circulation being the best answer.

Correct answer: A. It is highly eroded and relatively lower in height

The correct answer is A. The Aravalli Range is one of the oldest fold mountain systems in the Indian subcontinent. Because it has been exposed to weathering and erosion for a very long geological period, its original sharp peaks and continuous high relief have been reduced in many places. It now appears as a broken and relatively low range extending through parts of Rajasthan toward Haryana and Delhi. This contrasts with the young, tectonically active Himalayas, which are much higher and more rugged. The Aravalli is not submerged, nor is it made of ice; those statements are physically incorrect. Therefore, its great age is best expressed through its extensive erosion, fragmented form, and comparatively modest elevation.

Correct answer: A. It forms a broad plateau region in southern India

The correct answer is A. The Deccan Plateau is the extensive upland occupying a large part of southern Peninsular India, broadly between the Western Ghats and the Eastern Ghats. It has an elevated, gently sloping surface and is underlain in many areas by ancient rocks and extensive basaltic lava flows. Weathering of these basaltic rocks has contributed to the formation of black soil, which supports important crops such as cotton. The plateau is not a Himalayan range, a delta formed by the Ganga and Brahmaputra, or a narrow coastal lagoon. Its large area, central position in the peninsula, and distinctive plateau structure explain why it is regarded as the main part of Peninsular India. Hence option A is correct.

Correct answer: A. Deccan Plateau

The correct answer is A, the Deccan Plateau. The Telangana Plateau and Karnataka Plateau are regional divisions or parts of the broad Deccan upland in southern Peninsular India. They share the general characteristics of an elevated interior surface, ancient crystalline rocks, and in many places basaltic or related plateau geology. The Deccan region extends across a large part of the peninsula and is drained by rivers such as the Godavari, Krishna, and their tributaries. The Meghalaya Plateau is an isolated northeastern upland, the Ladakh Plateau lies in the high-altitude Trans-Himalayan region, and the Malwa Plateau is a separate central Indian unit north of the Deccan. Since both named plateaus belong to the southern peninsular highland, option A is the correct larger regional classification.

Correct answer: A. Cutting by peninsular rivers

The governing geographical concept is the difference between continuous and discontinuous mountain systems. The Eastern Ghats are not one unbroken wall because several major peninsular rivers, including the Mahanadi, Godavari, Krishna and Cauvery, have cut valleys and gaps through them on their way to the Bay of Bengal. Therefore, option A correctly explains their broken nature. Glaciers do not shape this tropical peninsular range in the manner suggested by option B, while desert sand and coral reefs have no role in forming these inland hills. The Western Ghats, by comparison, are more continuous.

Correct answer: A. Meghalaya and North-east India

The governing concept is the regional distribution of India’s plateaus. The Shillong Plateau is a detached, elevated plateau in the north-eastern part of the country and is chiefly associated with Meghalaya. It forms an important part of the Meghalaya Plateau and is separated from the main Peninsular Plateau by surrounding lowlands and structural features. Hence option A is correct. Rajasthan and the Aravalli belong to western India, Kerala and the western coast refer to a coastal and Western Ghats setting, and Ladakh and the Karakoram belong to the high mountain region of the north. These alternatives therefore identify different physical regions.

Correct answer: A. Purvanchal and North-east India

The governing concept is the classification of India’s mountain and hill systems by region. The Naga, Mizo and Patkai Hills lie in the north-eastern hill region and are commonly grouped with the Purvanchal ranges, which form an eastern continuation of the Himalayan mountain system. Therefore, option A is correct. The Aravalli is an old mountain system of western India, the Satpura lies mainly in central India, and the Nilgiri Hills belong to the southern part of the Peninsular Plateau. Those locations are geographically separate from the Naga, Mizo and Patkai Hills. The question asks for their broad regional identity, not for a single state name.

Correct answer: A. Mount Abu and Guru Shikhar

The governing concept is the identification of important ranges, peaks and hill stations in India. Mount Abu is the well-known hill station situated in the Aravalli Range of Rajasthan, and Guru Shikhar, located near Mount Abu, is the highest point of the Aravalli Range. Thus option A correctly combines the tourist location with the associated highest peak. Ooty and Doddabetta belong to the Nilgiri Hills, Pachmarhi and Dhupgarh are associated with the Satpura region of Madhya Pradesh, and Cherrapunji and Mawsynram are in Meghalaya. These distractors are genuine geographical places, but they do not belong to the Rajasthan Aravalli context.

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

The governing concept is the comparative structure of the two major escarpments of Peninsular India. The Western Ghats run more continuously along the western edge of the Deccan Plateau, although passes and valleys occur in places. The Eastern Ghats are more discontinuous because rivers such as the Mahanadi, Godavari, Krishna and Cauvery have cut across them before reaching the Bay of Bengal. Therefore option A is correct. The Eastern Ghats are not a snow-covered system, so B is false. Both ranges are not desert dunes, and the Western Ghats are part of the Peninsular Plateau rather than an outer Himalayan range, ruling out C and D.

Correct answer: A. Jharkhand and mineral region

The governing concept is the relationship between plateau regions, rock structure and mineral resources. The Singhbhum Plateau lies mainly in Jharkhand and forms part of the broader Chota Nagpur Plateau region. It is well known for ancient rocks and important deposits of iron ore and other minerals, which have supported mining and industrial development. Hence option A is the most appropriate association. Kerala is noted for its coastal backwaters, Rajasthan for arid landscapes and sand dunes, and Sikkim for Himalayan mountains and glaciers. Although each distractor names a real Indian geographical feature, none describes the location and economic-geological identity of the Singhbhum Plateau.

Correct answer: A. Deccan Plateau region

The governing concept is the regional classification of hill ranges within the Peninsular Plateau. The Balaghat Range is associated with the Deccan Plateau and extends through parts of the Maharashtra–Karnataka upland region. It is an old peninsular highland rather than a young Himalayan or alluvial landform. Therefore option A is correct. The Ganga Plain is a level depositional plain formed largely by river sediments, the Sikkim Himalaya belongs to the young fold mountains of the north, and the Meghalaya Plateau is an isolated north-eastern plateau. These regions differ in origin, location and relief, so they cannot provide the appropriate wider association for the Balaghat Range.

Correct answer: A. Trans-Himalayan highland

The governing concept is the division of the Himalayan system into the Himalaya proper and the Trans-Himalaya. The Zanskar and Ladakh ranges lie north of the main Great Himalayan range and are included in the Trans-Himalayan highland region. Much of this area is cold, dry and located at high elevation, with Ladakh forming a characteristic rain-shadow landscape. Thus option A is correct. The eastern coastal plain and the Ganga Delta are low-lying depositional regions, while the Thar Desert is an arid lowland and dune region. None of these alternatives represents the high, rugged mountain terrain of Zanskar and Ladakh.

Correct answer: A. It is associated with old rocky plateau parts of Karnataka

The governing concept is the geological and physiographic importance of the ancient Peninsular Plateau. The Dharwar region is associated with old crystalline rocks and plateau landscapes of southern India, especially Karnataka. These ancient formations are significant in the study of Indian physical geography and are also linked with mineral-bearing areas. Therefore option A correctly identifies its broad physical setting. The Ganga floodplain is a young alluvial depositional region, a coral island is a marine landform, and the outer Himalayan range belongs to a much younger mountain system formed by folding. Options B, C and D therefore describe entirely different landforms and geological environments.

Correct answer: A. Southern Western Ghats

The governing concept is the regional distribution of hill ranges within the Western Ghats. Agasthyamalai and the Cardamom Hills are located in the southern section of the Western Ghats, near the Kerala–Tamil Nadu border and adjoining highlands. Agasthyamalai is a prominent southern Western Ghats massif, while the Cardamom Hills are also part of this humid, elevated mountain belt. Hence option A is correct. The Eastern Himalayas are far to the north-east, the northern Aravalli lies in north-western India, and the Ganga Plain is a broad alluvial lowland. These alternatives differ both in location and in physical origin from the southern Western Ghats.

Correct answer: A. Western Ghats form a high range near the western edge of the Deccan Plateau

The governing concept is the physical division and relief of Peninsular India. The Deccan Plateau is a broad elevated triangular region south of the Narmada, while the Western Ghats form a prominent mountain escarpment along its western margin, broadly parallel to the Arabian Sea coast. Therefore, option A correctly describes their relative position. Option B is wrong because the Western Ghats are far south of the Ganga Plain. Option C reverses the location of the Deccan Plateau, which lies south of the Himalayas, and option D incorrectly treats a large mainland plateau as an island. The Western Ghats also influence monsoon rainfall and contain important passes.

Correct answer: A. Himalayas mountain and Deccan Plateau

The governing concept is the classification of India’s major physiographic divisions. The Himalayas are a young, high fold-mountain system in northern India, whereas the Deccan is a large ancient plateau in Peninsular India. Thus, option A combines one genuine mountain system with one genuine plateau. Chilika is a lagoon, not a mountain, and the Ganga is mainly associated with a vast alluvial plain rather than a standard geographical unit called the Ganga Plateau. The Thar is a desert, Wular is a lake, and Sambhar is a salt lake; neither pair provides the stated mountain-and-plateau combination. Yamuna is a river, so option D is also invalid.
