Mountains and Plateaus of India

The Himalayas are the great mountain system along the northern margin of India. They extend broadly from the north-west toward the north-east and form a major physical barrier between the Indian subcontinent and the Tibetan Plateau. In school geography, they are classified as young fold mountains, formed through the collision of the Indian and Eurasian tectonic plates. Option A is therefore correct. The Aravalli Range lies mainly in north-western India, the Satpura Range is in central India, and the Nilgiri Hills are in the southern part of the Peninsular Plateau. These ranges are important, but none occupies India’s northern boundary in the same way as the Himalayas.

The Deccan Plateau is a broad elevated upland forming a major part of Peninsular India. A plateau is a relatively extensive area of land that stands higher than the surrounding region and often has a fairly level or gently undulating surface. The Deccan is bordered by the Western and Eastern Ghats and slopes generally eastward, allowing many rivers to flow toward the Bay of Bengal. Option C is correct because it identifies the basic landform category. A river plain is a low, depositional surface, a coastal lagoon is a water body separated from the sea, and a glacial region is shaped mainly by moving ice; none describes the Deccan Plateau’s primary form.

The Western Ghats, also called the Sahyadri, form a nearly continuous mountain chain along the western edge of Peninsular India. They run broadly parallel to the Arabian Sea and rise close to the western coast, while the Deccan Plateau lies to their east. Their position strongly affects rainfall: moist monsoon winds rise along the range and produce heavy rain on the western, windward side, with a rain-shadow effect in parts farther east. Option D is correct. Eastern India is not their main location, the north-west contains the Aravallis and other ranges, and the Middle Himalaya belongs to the Himalayan mountain system, not the Western Ghats.

The correct answer is A, the Eastern coast. The Eastern Ghats are a discontinuous chain of hills extending along the eastern side of peninsular India, broadly parallel to the Bay of Bengal coastline. They occur mainly through parts of Odisha, Andhra Pradesh and Tamil Nadu, although their alignment is interrupted by major rivers such as the Mahanadi, Godavari, Krishna and Kaveri. The Western Ghats, in contrast, lie along the Arabian Sea side and are therefore not the answer. Kachchh and Konkan are coastal regions, but neither represents the coast associated with the Eastern Ghats. Thus, the geographical association is Eastern Ghats–eastern coast.

The correct answer is B, the Eastern Ghats and Western Ghats. The Nilgiri Hills form an important highland region in southern India, mainly around the junction where the Western Ghats meet the Eastern Ghats. Their name means Blue Mountains, and they are located near the borders of Tamil Nadu, Kerala and Karnataka. The Aravalli and Vindhya ranges are separate formations of western and central India, so option A is incorrect. Satpura is a central Indian range and the Himalaya lies far to the north; they do not meet at the Nilgiris. Shiwalik and Pir Panjal are Himalayan ranges, making option D geographically unrelated.

The correct answer is C, Central India. The Vindhya Range is a major upland system of central India, extending broadly across parts of Madhya Pradesh and adjoining areas. In traditional geographical descriptions, the Vindhyas are associated with the boundary between the northern plains and the Deccan region, although the exact historical and physical meaning of this boundary can vary. The Andaman Islands and Lakshadweep are island groups, not parts of the Vindhya system. The phrase north-eastern islands does not identify the location of this range either. Therefore, the regional clue in the question clearly points to Central India, making option C the only suitable answer.

The correct answer is D, the Narmada Valley. The Satpura Range lies south of the Narmada River valley in central India. A useful way to remember the arrangement is that the Vindhya Range is generally north of the Narmada, while the Satpura Range is south of it. The Narmada flows westward through a rift valley between these upland systems before reaching the Arabian Sea. The Ganga and Brahmaputra valleys are much farther north and are associated with the Himalayan and northern plain regions. The Godavari is an important peninsular river, but its valley is not the standard geographical reference for locating the Satpuras. Hence option D is unambiguous.

The correct answer is A, coal and iron ore. The Chota Nagpur Plateau, located mainly in Jharkhand and extending into neighbouring parts of eastern India, is one of the country’s most important mineral-producing regions. Its ancient crystalline rocks and geological structure contain large deposits of coal, iron ore, mica, bauxite and other minerals. Coal supports thermal power and several industries, while iron ore supplies the iron and steel sector. Coconut is an agricultural product rather than the defining mineral resource of this plateau. Sea salt and pearls are associated with coastal or marine environments, whereas Chota Nagpur is an inland plateau. Therefore option A best represents its mineral importance.

The correct answer is B, north-eastern India. The Meghalaya Plateau is an extension of the Peninsular Plateau into the north-eastern part of the country. It is mainly associated with Meghalaya and includes the Garo, Khasi and Jaintia Hills. The plateau is separated from the main Peninsular Plateau by the alluvial plains of the Ganga and Brahmaputra systems, but its ancient rocks show its geological connection with peninsular India. Western, south-western and north-western India contain other physical regions, such as the Western Ghats, coastal plains, deserts and the Aravallis, not the Meghalaya Plateau. Hence the regional location clearly makes option B correct.

The correct answer is D, Shiwalik. The Himalayan system is commonly described from north to south as the Great Himalaya or Himadri, the Lesser or Middle Himalaya also called Himachal, and the Outer Himalaya or Shiwalik. Therefore, when the question asks for the southernmost or outermost range, Shiwalik is the appropriate term. Himadri is the highest and northernmost main range, so option A is not correct. Himachal occupies the middle position, while the Karakoram is a high mountain system north of the main Himalayan ranges and is not the southernmost Himalayan division. The Shiwaliks are comparatively low and young foothill ranges, completing the reasoning for option D.

The correct answer is A, Himadri. Himadri is the traditional name for the Great Himalaya, the highest and northernmost of the three main parallel Himalayan ranges. It contains many permanently snow-covered peaks and includes some of the world’s highest mountains. Shiwalik is the low, outermost and southernmost range, so option B describes the opposite part of the Himalayan system. Aravalli is an old fold mountain system of western India, while Vindhya is a central Indian range; neither is a main Himalayan division. The wording “highest and northern main range” therefore points directly to Himadri, making option A unambiguous.

The correct answer is B, Himachal. The Middle Himalaya is also called the Lesser Himalaya or Himachal range. In the usual north-to-south arrangement, it lies between the high, snow-covered Himadri or Great Himalaya and the lower, outer Shiwalik range. Satpura is a separate mountain range of central India, so option A is unrelated. The Eastern Ghats are discontinuous hills along the eastern side of peninsular India, and Deccan refers mainly to a plateau region, not a Himalayan range. Recognising the sequence Himadri–Himachal–Shiwalik helps identify the middle division and confirms that option B is correct.

The correct answer is C, the Deccan Plateau. Large parts of the Deccan Plateau are formed from ancient basaltic lava flows associated with volcanic activity. Weathering of these basalt rocks produced regur, or black soil, which has a high capacity to retain moisture and is especially suitable for cotton cultivation. The Malwa Plateau also contains areas of black soil, so it may appear plausible, but the broad and standard association of lava rocks and black soil in Indian geography is the Deccan Plateau. Meghalaya and Bundelkhand have different geological settings and are not the best answer to this paired clue. Thus, option C is the most precise choice.

The correct answer is Madhya Pradesh because the Malwa Plateau occupies a major part of western Madhya Pradesh in central India, with extensions toward southeastern Rajasthan. It is a subdivision of the Peninsular Plateau and is known for its elevated, lava-based terrain and black soil in many areas. The plateau is drained by rivers such as the Chambal, Betwa and Kali Sindh. Kerala is a coastal and Western Ghats state, Manipur lies in the northeastern hills, and Sikkim belongs to the Eastern Himalayas; none of these states is chiefly associated with the Malwa region. Therefore, option D is the only geographically appropriate choice.

The correct answer is the Western Ghats. The Eastern Ghats are discontinuous and irregular because several major rivers, including the Mahanadi, Godavari, Krishna and Kaveri, have cut across them on their way to the Bay of Bengal. In contrast, the Western Ghats form a more continuous escarpment along the western edge of the Deccan Plateau, although they too contain passes and local breaks. Shiwalik and Pir Panjal are Himalayan ranges, while the Aravalli is an old, separate range of northwestern India. The comparison in the question is therefore specifically between the two coastal-edge ghats, making option B correct.

The correct answer is South India. The Annamalai Hills, also called the Anaimalai Hills, lie in the southern part of the Western Ghats, mainly around the Kerala–Tamil Nadu border. They are connected with the highland system of the southern Western Ghats and are near important peaks such as Anamudi. This location places them firmly in peninsular South India rather than in the Himalayan or northwestern regions. North India includes the Himalayas, eastern India includes different hill and plateau areas, and western Rajasthan is dominated by the Thar Desert and the Aravalli region. Thus, option C correctly identifies the broad geographic part of India.

The correct answer is the Aravalli Range. It is regarded as one of the oldest fold mountain systems in India and has been greatly worn down by prolonged weathering and erosion. The range extends broadly from the Delhi region through Rajasthan toward Gujarat, with its highest well-known summit at Guru Shikhar. The Himalayas are geologically young fold mountains, formed much later through the collision of the Indian and Eurasian plates. The Shiwalik is the youngest outer Himalayan range, while the Eastern Ghats are ancient discontinuous hills but are not the standard answer to this well-known comparison. Therefore, option D is correct.

The correct answer is the Himalayas. The Pir Panjal is an important range of the Lesser, or Middle, Himalaya, also called the Himachal range. It extends mainly through the Jammu and Kashmir region and continues toward Himachal Pradesh, forming a major mountain barrier south of the Kashmir Valley. The range is associated with high passes and valleys and is structurally part of the Himalayan system. The Deccan Plateau is a peninsular plateau, while the Aravalli and Satpura are separate old ranges of peninsular or central India. Since the question asks for the larger mountain system, option B is the unambiguous answer.

The correct answer is Sikkim. Kanchenjunga, one of the world’s highest peaks, stands in the eastern Himalaya on the boundary between Sikkim and Nepal, and it is strongly associated with Sikkim in Indian geography. Its snow-covered summit and surrounding high mountains are important features of the state’s Himalayan landscape. Goa is a coastal state, Haryana is part of the northern plains, and Telangana lies on the Deccan Plateau; none of these has a peak comparable to Kanchenjunga within its geographic setting. In school-level questions, the expected state association is Sikkim, so option C is correct.

The correct answer is Uttarakhand. Nanda Devi is a major Himalayan peak located in the Garhwal Himalaya of Uttarakhand, and it is the highest mountain situated entirely within India. The peak and the surrounding Nanda Devi National Park are important geographic features of the state. Rajasthan is associated with the Aravalli Range and the Thar Desert, Bihar lies mainly in the Gangetic plains, and Tamil Nadu includes the southern Eastern and Western Ghats rather than the central Himalaya. These contrasts make the location clear. Therefore, the state connected with Nanda Devi in this question is Uttarakhand, represented by option D.

The correct answer is the Eastern Ghats. The Western Ghats form a relatively continuous, elevated escarpment along the western margin of the Deccan Plateau, while the Eastern Ghats are lower in continuity and are divided into separate sections by rivers such as the Mahanadi, Godavari, Krishna and Kaveri. The Western Ghats also act as an important barrier to the southwest monsoon, causing substantial orographic rainfall on their western slopes. The Himalayas, Aravalli and Shiwalik are different mountain systems, so they are not the intended comparison. Therefore, option B correctly identifies the range that is more broken than the Western Ghats.

The correct answer is the Western Ghats. The Palghat Gap, or Palakkad Gap, is a broad natural break in the southern Western Ghats between the Nilgiri Hills to the north and the Anaimalai Hills to the south. It provides an important passage between Kerala and Tamil Nadu and has long supported transport, communication and movement across the mountain barrier. The Satpura and Aravalli ranges lie in central and northwestern India, while the Shiwalik belongs to the outer Himalayas. Since Palghat Gap is a well-known pass-like break of the southern Western Ghats, option C is correct.

The correct answer is Meghalaya because the Shillong Plateau forms the central highland of Meghalaya in north-eastern India. Shillong, the capital of Meghalaya, lies on this plateau, which is also commonly described as an extension of the Peninsular Plateau separated from the main block by the Garo-Rajmahal gap. The question tests the geographical association between a plateau and its state, not the location of a river or city alone. Maharashtra, Gujarat, and Karnataka contain other plateau regions, but none is associated with the Shillong Plateau. Therefore, option D is the only suitable answer.

The correct answer is Uttar Pradesh and Madhya Pradesh. The Bundelkhand Plateau occupies a broad region of central India, extending across southern Uttar Pradesh and northern Madhya Pradesh. It is known for an old, hard crystalline-rock surface, uneven relief, shallow soils in many places, and areas affected by water scarcity and erosion. The wording “mainly associated” is important because the plateau is not confined to one state or one district. Kerala and Tamil Nadu belong to the southern peninsular region, Assam and Manipur are in the north-east, and Punjab and Haryana lie in the northern plains. Thus, option A correctly identifies the two states.

The correct answer is Jharkhand. The Chota Nagpur Plateau occupies most of Jharkhand and also extends into adjoining parts of Odisha, West Bengal, Chhattisgarh, and Bihar. In school geography, it is especially associated with Jharkhand because the state forms its central and most recognizable part. The plateau is built largely of ancient crystalline rocks and is famous for rich deposits of coal, iron ore, mica, bauxite, and other minerals. Kerala and Goa are coastal or western peninsular states with different physical settings, while Punjab is primarily part of the northern alluvial plain. These contrasts make option B the only appropriate choice.
