Key Points at a Glance

  1. 1

    The Graduation Level 2026 syllabus places this topic under Geography of India: physical features; climate and monsoon; major rivers, dams, lakes and oceans; wildlife and sanctuaries; population indicators; disaster management and climate change.

  2. 2

    India is commonly read through six macro physiographic units: Northern and North-eastern Mountains, Northern Plain, Peninsular Plateau, Indian Desert, Coastal Plains and Islands.

  3. 3

    The Himalaya is arranged from north to south as Himadri, Himachal and Shiwalik; the Shiwalik foothills feed the Bhabar-Terai-Bhangar-Khadar sequence of the northern alluvial plain.

  4. 4

    The Peninsular Plateau is an old crystalline block; the Central Highlands lie mainly north of the Narmada, while the Deccan Plateau spreads southward between the Ghats.

  5. 5

    The Western Ghats, or Sahyadri, are higher and more continuous than the Eastern Ghats, so they form a stronger watershed and rainfall barrier.

  6. 6

    The southwest monsoon normally sets in over Kerala around 1 June and usually covers India by early to mid-July; retreating monsoon rain is crucial for the Tamil Nadu coast.

  7. 7

    Himalayan rivers are mostly perennial and sediment-rich; peninsular rivers are mostly rain-fed and follow older plateau slopes, with Narmada and Tapi as west-flowing rift-valley exceptions.

  8. 8

    ISFR 2023 records India's forest and tree cover at 8,27,357 sq km, or 25.17% of geographical area; the National Forest Policy goal remains one-third forest/tree cover at national level.

  9. 9

    Rajasthan links national geography through the Aravalli old fold mountain system, Thar Desert, Luni inland drainage, Sambhar salt lake and Chambal-Banas eastern drainage.

Syllabus Frame and Physiographic Base

For CET Graduation Level 2026, this lesson belongs to the official Geography of India block: physical features; climate and monsoon system; major rivers, dams, lakes and oceans; wildlife and sanctuaries; population growth, density, literacy and sex ratio; disaster management and climate change. The topic is therefore not just a list of mountains and rivers. It asks you to connect landform, climate, drainage, vegetation, conservation and risk on the map.

India is commonly read through six macro physiographic units: the Northern and North-eastern Mountains, the Northern Plain, the Peninsular Plateau, the Indian Desert, the Coastal Plains and the Islands. Each unit has a different geological age, relief, slope, soil base, river behaviour and vegetation pattern. The Himalaya is young and tectonically active; the Northern Plain is a deep alluvial belt; the Peninsular Plateau is old and crystalline; the Indian Desert shows aridity and internal drainage; the coasts and islands link land with the Indian Ocean.

Rajasthan is a useful bridge from national geography to local examples. A west-east view across the state moves from the Thar Desert and saline depressions through the Aravalli divide toward more river-linked plains and plateau margins. The core exam idea is simple: landforms are the base layer on which climate, drainage, soils, vegetation, settlement and hazards are built.
