Physical Features of India

From north to south the order is Himadri Himachal and Shiwalik. For exams remember the Himalayan ranges with a map.

The Himalayas are young fold mountains formed by the collision of Indian and Eurasian plates. For exams remember plate collision.

Himadri is the highest range of the Greater Himalaya. For exams link high peaks and glaciers with Himadri.

Dun valleys occur between Shiwalik and Lesser Himalaya. For exams remember Dehradun as an example.

Bhabar has coarse pebbles so water sinks underground. For exams connect Bhabar with Himalayan foothills.

Terai is a moist and marshy belt south of Bhabar. For exams remember Bhabar as pebbly and Terai as moist.

Northern Plains are formed by alluvial deposition of rivers. For exams remember the Indus Ganga Brahmaputra river systems.

Khadar receives fresh alluvium from floods and is more fertile. For exams remember Khadar new and Bhangar old.

The alluvial land between two rivers is called a doab. For exams remember Punjab and Ganga Yamuna Doab.

The Peninsular Plateau is made of very ancient igneous and metamorphic rocks. For exams remember it as an old stable landmass.

Central Highlands lie north of the Narmada and Deccan Plateau lies south of it. For exams remember the position of Narmada.

Deccan Trap is a basalt region formed by huge lava flows. For exams connect it with black soil.

The direct answer is option A, abundant coal, iron ore, and other minerals. The Chotanagpur Plateau, spread mainly across Jharkhand and adjoining parts of eastern India, contains extensive deposits of important minerals. Coal supports power and industry, iron ore supports iron and steel production, and other minerals such as mica and bauxite add to the region's resource importance. This concentration of mineral wealth is why it is called India's mineral heartland. Option A is correct because it states the economic and geological reason for the name. Option B is wrong because corals are marine organisms or reef materials, not the defining resource of this inland plateau. Option C is wrong because the plateau is made of old, hard rocks; saying it has no rocks is the opposite of reality. Option D is wrong because Chotanagpur is an inland plateau, not a sea island. The reasoning cue is: Jharkhand plus coal and iron ore strongly points to Chotanagpur Plateau. Mineral wealth supports mining, power generation, metal industries, and related development, though it can also create environmental challenges.

The Meghalaya Plateau is considered a separated northeastern part of the Peninsular Plateau. For exams remember Garo Khasi Jaintia.

The direct answer is C: the Western Ghats intercept the southwest monsoon winds. In summer, moist southwest monsoon winds from the Arabian Sea move towards India. The Western Ghats stand across this path. Step by step: moist winds approach from the southwest; the mountain barrier forces them to rise; rising air cools; water vapour condenses; rain falls mainly on the windward western slopes. The eastern side lies in a relative rain-shadow area, so it generally receives less rainfall. Option A is wrong because the Western Ghats are not in the Thar Desert. Option B is wrong because they are land mountains, not submerged in the Bay of Bengal. Option D is wrong because they are not coral islands. Option C correctly identifies the orographic barrier. Remember: windward Western Ghats receive heavy monsoon rain; leeward slopes are drier.

Narmada and Tapi are west flowing peninsular rivers. For exams connect them with rift valleys and Arabian Sea.

East flowing peninsular rivers form deltas on the eastern coast. For exams remember the Bay of Bengal.

The Thar Desert is a region of low rainfall and high dryness. For exams remember Rajasthan and lack of rainfall.

The Rann of Kachchh is a broad saline marshy plain in Gujarat. It is known for its low-lying landscape, seasonal waterlogging, and extensive salt deposits. In the dry season, much of the surface becomes bright and salt-covered, while during wetter periods parts of the area may hold shallow water. The word “Rann” is strongly associated with this distinctive salty marsh environment rather than with high mountains or a typical plateau.

Option D is correct because it describes a saline marshy plain. High Himalayan peaks belong to a very different mountain region. Coral islands are coastal island formations, and black lava soil is associated with basaltic volcanic areas, not the main physical identity of the Rann. Thus, connecting Kachchh with Gujarat, salt, marshes, and seasonal wetness leads to the correct choice.

Western coastal plains are narrow because there is little space between Western Ghats and Arabian Sea. For exams remember coastal comparison.

Large river deltas form on the eastern coastal plains so they are broader. For exams link eastern coast with deltas.

Lakshadweep lies in Arabian Sea to the west and Andaman Nicobar lies in Bay of Bengal to the east. For exams remember sea location.

Barren Island in the Andaman region is famous for an active volcano. For exams remember volcanic island.

Majuli is a river island linked with the Brahmaputra in Assam. For exams separate river islands from sea islands.

Palk Strait is a shallow sea passage between Tamil Nadu and Sri Lanka. For exams identify it on the map.
