The Peninsular Plateau

The Peninsular Plateau is an ancient, relatively stable tableland made of hard crystalline rocks. Its western edge is marked by the Western Ghats, also called the Sahyadri in many places. This range runs roughly parallel to the western coast and forms a fairly continuous escarpment. The Eastern Ghats lie along the eastern side, but they are more discontinuous because rivers cut through them. This directional distinction is central to identifying the plateau’s boundaries.

Option A is correct because the Western Ghats stand along the western margin of the Peninsular Plateau. The Eastern Ghats belong to the eastern margin, while the Himalayas and Karakoram are much younger and belong to the northern mountain region. The question asks specifically for the western edge, so the name and direction match only Western Ghats. Therefore, the correct choice is A.

The Peninsular Plateau is bordered by important hill ranges on different sides. The Eastern Ghats mark much of its eastern edge and run roughly parallel to the eastern coast, though they are discontinuous because several rivers cut through them. The Western Ghats lie along the western edge, while the Vindhya and Satpura ranges occupy other parts of central India.

Therefore, option B is correct. The question asks specifically for the major range on the eastern edge, so Eastern Ghats is the direct match. Western Ghats would be correct for the western edge, not the eastern one. Vindhya and Satpura are important central Indian ranges but do not answer this particular boundary question. Remembering the paired names with their sides helps avoid reversing the Ghats.

Vindhya is an important range linked with the southern side of the Central Highlands. Place Vindhya in central India in exams.

These hills are linked with the eastern and central parts of the Peninsular Plateau. Remember them near the Deccan region in exams.

The Deccan Plateau forms a triangular landmass. Remember it as a plateau extending toward the south in exams.

Direct answer: Option A, old hard rocks. The Peninsular Plateau is a very old part of India. Its rocks formed long ago and contain metallic and non-metallic minerals such as iron ore, coal, and manganese. Therefore the age and hard rocky structure explain its mineral importance. Option A is correct because ancient rocks commonly preserve valuable mineral deposits. Option B is wrong: the plateau is not made only of sea sand. Option C is wrong: it is not covered with glacial ice. Option D is wrong: it is not a new alluvial plain; alluvial plains are mainly river-deposited sediments. Memory cue: old plateau rocks often mean rich mineral resources.

The direct answer is A, Deccan Trap. Black soil is strongly associated with the basaltic lava rocks of the Deccan Trap region in the Peninsular Plateau. Over a long time, weathering of basalt produces clay-rich, dark soil, commonly called regur or black cotton soil. Step by step: ancient lava flows cooled to form basalt; basalt weathered and released fine mineral material; this material developed into deep black soil. Option A is correct because the Deccan Trap is the classic Indian region of black soil. Option B, the Ganga Plain, is mainly a vast alluvial region built by river deposits, so its characteristic soil is alluvial rather than specifically black soil. Option C, the Sundarbans, is a deltaic and tidal area known for muddy alluvium and mangrove vegetation. Option D, Ladakh, is a cold, high-altitude region with dry conditions and different thin soils. Black soil can occur beyond the Deccan, but among these options the Deccan Trap is the precise association. Memory cue: dark basalt lava gives dark regur soil.

The Godavari is one of the major rivers of peninsular India. It rises in the western part of the Deccan Plateau and flows generally eastward across the plateau before reaching the Bay of Bengal. Its basin covers a large part of central and southern India, and several tributaries join it along the way. This makes the river strongly associated with the Deccan Plateau and the physical geography of South India.

Option A is correct because the Godavari is a major plateau river, not a Himalayan river, Punjab Plain river, or Thar Desert river. The Himalayas are linked with rivers such as the Ganga and Brahmaputra, while the Punjab Plain is associated with the Indus river system. The Thar is an arid region with different drainage features. Linking the Godavari with the Deccan Plateau is therefore the appropriate regional identification.

Krishna and Kaveri are major rivers of peninsular India. Link them with the Deccan Plateau in exams.

The direct answer is A, westward. Narmada and Tapi are important west-flowing rivers of the Peninsular Plateau. Step by step: both rivers rise in the central Indian highland region; they travel generally toward the west; they use west-opening valleys and estuaries; they finally enter the Arabian Sea. Option A is correct. Option B is wrong because many other Peninsular rivers, such as the Mahanadi, Godavari, Krishna, and Cauvery, generally flow eastward, but Narmada and Tapi are notable exceptions. Option C is wrong because their overall courses are not toward the north. Option D is wrong because they do not generally flow southward. The word ‘generally’ allows for local bends in a river’s course; it asks for the overall direction, not every small turn. Memory cue: most major Peninsular rivers flow east, but Narmada and Tapi flow west to the Arabian Sea.

The Eastern Ghats are less continuous and lower than the Western Ghats. This comparison is very useful in exams.

The Western Ghats block moisture bearing winds from the Arabian Sea. Understand them as barrier mountains in exams.

The Peninsular Plateau is called a stable landmass because it is one of the oldest parts of the Indian subcontinent. Much of it consists of ancient crystalline igneous and metamorphic rocks that have remained comparatively firm and resistant for a very long time. It has experienced erosion and some local movements, but it is generally less tectonically active than young fold mountain regions.

Option A is correct because old and hard rocks explain the plateau’s broad stability. New alluvial soil describes river plains, not the basic structure of the Peninsular Plateau. It is not covered by seawater, nor does it change shape every day. The word “stable” here refers to geological structure and relative tectonic firmness, not to an absence of all erosion or any geological change.

The Central Highlands slope toward the north and east. Understand the direction from the flow of its rivers in exams.

The direct answer is A, Old range. The Aravalli Range is one of India’s oldest mountain systems. It has been worn down by weathering and erosion over a very long geological period, so its height and sharpness are generally less than those of young fold mountains. Option A is correct because Aravalli is classified as an ancient or old range and is associated with the Central Highlands of the Peninsular Plateau. Option B, a young fold range, describes newer mountain systems formed by strong folding, such as the Himalayas; the Aravallis are much older and more eroded. Option C, a marine range, is not the standard classification of the Aravallis; the range is a continental landform. Option D, a glacial island, is not a mountain-range type at all and does not describe the Aravallis. The reasoning is therefore based on age, geological history, and degree of erosion. Memory cue: old ranges are lower and more worn; Aravalli is India’s ancient worn range.

The Peninsular Plateau has old hard rocks and the Northern Plains have alluvial deposits. Remember this basic difference in exams.

The Himalayas are a separate mountain division and not part of the Peninsular Plateau. Remember India's physical divisions separately in exams.

The Deccan Plateau is higher in the west and slopes eastward. Remember the west to east slope in exams.

The Peninsular Plateau is an old hard and triangular landmass. These three words identify it in exams.

The Vindhya Range forms the southern edge of the Central Highlands. In exams, remember Vindhya near the Narmada region.

The Aravalli Range lies to the northwest of the Central Highlands. In exams, remember Aravalli as a very old mountain range.

The Malwa Plateau is an important part of the Central Highlands. In exams, link Malwa with the plateau region of central India.

The Central Highlands generally slope from west to east. In exams, identify slope through river flow direction.

Bundelkhand and Baghelkhand are eastern extensions of the Central Highlands. In exams, link them with the central plateau region.

The Chotanagpur Plateau is famous for minerals. In exams, remember it as a major mineral region of India.
