Physical Features of India

The eastern coastal plain is broad and east flowing rivers deposit silt there. For exams remember delta and eastern coast together.

The western coast is narrow and west flowing rivers are generally short. For exams compare western and eastern coasts.

Konkan Kannad and Malabar are north to south parts of the western coastal plain. For exams remember this order.

Northern Circars and Coromandel are eastern coastal parts linked with Bay of Bengal. For exams identify the eastern coast.

In desert regions wind deposits sand and forms dunes. For exams remember Thar and wind action.

Luni is a river of dry western Rajasthan and does not form a clear sea delta. For exams remember inland drainage.

Seasonal waterlogging and evaporation leave a saline surface in the Rann. For exams remember Rann as salt flat.

Ladakh is cold and dry due to altitude and Himalayan rain shadow. For exams remember the cause of cold desert.

Lakshadweep is a coral island while Deccan Plateau is linked with basaltic lava. For exams keep island and plateau separate.

Barren Island is known as India's active volcanic island. For exams remember the Andaman region.

Majuli is a river island while Sundarbans is a mangrove area of the Ganga Brahmaputra Delta. For exams keep island and delta separate.

Indira Point in Nicobar is India's southernmost point while Kanyakumari is mainland southern tip. For exams avoid this confusion.

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

Meghalaya hills can block moist winds and cause heavy rainfall. For exams remember Khasi Hills and rainfall areas.

Himalayan rivers receive water from both glaciers and rain. For exams remember perennial and seasonal difference.

Coastal plains are useful for ports due to sea contact and relatively flat land. For exams remember coast and trade relation.

Western Ghats are close to sea while large deltas develop on eastern coast. For exams remember coastal comparison.

The direct answer is A, the leeward side of the Western Ghats. Rain shadow develops when moist winds rise over a mountain. The windward slope receives rain as air rises, expands and cools. After crossing the crest, the air descends on the opposite, leeward side; descending air warms and becomes relatively dry, so rainfall is low. Option A is correct because the Deccan side east of the Western Ghats is a classic Indian rain-shadow region. Option B, the Sundarbans Delta, is a wet delta, not a rain-shadow example. Option C, Lakshadweep coral, describes coral islands, not mountain-related rainfall. Option D, Ganga Khadar, is young alluvial soil near floodplains, not a rain-shadow landform. Exam cue: windward side is wetter; leeward side is drier.

The Terai is a low-lying belt along the Himalayan foothills. It receives much water from rivers and groundwater, so it is generally moist, marshy, and covered with grasses or forests in suitable places. It is not a dry sandy desert. The Thar is the Indian region commonly associated with dry sandy desert conditions. Therefore, the pairing in option B is clearly incorrect because it assigns desert characteristics to the Terai. The other pairings are geographically appropriate: the Deccan Trap is a basaltic lava plateau, the Sundarbans are a mangrove delta, and Lakshadweep consists mainly of coral islands.

The key is to connect each landform with its origin and environment. Repeated flooding, wet soils, and high moisture distinguish the Terai from an arid desert. A dry sandy description would fit the Thar much better, not the Terai. Thus option B is the only mismatched pair. The question asks for the clearly wrong match, so there is no need to reject the other three merely because their descriptions are brief.

Himalayas are young fold mountains while the Peninsular Plateau is an ancient stable landmass. For exams this comparison is very important.

Sundarbans is the tidal mangrove region of the Ganga Brahmaputra Delta. For exams identify this clue quickly.

Narmada flows west through a rift valley into the Arabian Sea. For exams remember the special course of Narmada.

Aravalli is among India's very ancient and eroded mountain ranges. For exams remember the difference between Aravalli and Himalaya.

Large deltas of east flowing rivers develop on the eastern coast. For exams remember Bay of Bengal and deltas.

India has many types of landforms so all physical divisions must be studied. For exams remember the six major divisions.
