Part of SSC CGL & Banking prep🧠 India is like a well-planned house
Picture India as a big house. The Himalayas are the tall protective roof in the north, the fertile Northern Plains are the busy living room where most people gather, the old Deccan Plateau is the solid stone floor in the south, and the oceans are the boundary walls on three sides. Once you can mentally 'walk through the house', the map stops being a blur of names.
India at a glance
- ✓Area is about 3.28 million sq km - the 7th-largest country in the world and the most populous.
- ✓Latitudinal extent: 8 degrees 4' N to 37 degrees 6' N; longitudinal extent: 68 degrees 7' E to 97 degrees 25' E.
- ✓The Tropic of Cancer (about 23.5 degrees N) cuts India almost in half and passes through 8 states.
- ✓Land neighbours: Pakistan, Afghanistan, China, Nepal, Bhutan, Myanmar and Bangladesh; maritime neighbours include Sri Lanka and Maldives.
| Reference line | Value | Why it matters |
|---|---|---|
| Tropic of Cancer | about 23 degrees 30' N | Passes through 8 Indian states |
| Standard Meridian | 82 degrees 30' E | Fixes Indian Standard Time (IST) |
| Latitudinal extent | 8 degrees 4' N to 37 degrees 6' N | The north-south spread of the mainland |
The Physical Divisions
| Division | Key features |
|---|---|
| The Himalayas | Young fold mountains in the north, in three ranges - Himadri (Greater), Himachal (Lesser) and the Shiwaliks (Outer) |
| Northern Plains | Fertile plains built by the Indus, Ganga and Brahmaputra; India's food bowl |
| Peninsular Plateau | The old, stable Deccan Plateau; rich in minerals; edged by the Western and Eastern Ghats |
| Indian Desert | The Thar in the west (Rajasthan); hot, sandy and dry |
| Coastal Plains | Western coast (Konkan, Malabar) and Eastern coast (Coromandel) |
| Islands | Andaman & Nicobar in the Bay of Bengal; Lakshadweep in the Arabian Sea |
Rivers - the two families
- ✓Himalayan rivers (Indus, Ganga, Brahmaputra) are perennial - fed by both rain and melting snow - and build the great plains.
- ✓The Ganga is the longest river flowing within India (about 2,525 km).
- ✓Peninsular rivers (Godavari, Krishna, Kaveri, Mahanadi) are mostly rain-fed and seasonal; the Godavari is the largest, nicknamed 'Dakshin Ganga'.
- ✓Most peninsular rivers flow east into the Bay of Bengal; the Narmada and Tapi are exceptions - they flow west into the Arabian Sea through rift valleys.
| Soil type | Where it is found / best for |
|---|---|
| Alluvial soil | Northern plains and river deltas; the most widespread and fertile; wheat and rice |
| Black (Regur) soil | The Deccan lava region; ideal for cotton |
| Red soil | Eastern and southern Deccan; needs fertilizers |
| Laterite soil | High-rainfall hilly areas; good for tea, coffee and cashew |
Quick revision
- ✓India: 7th-largest country; Tropic of Cancer passes through 8 states.
- ✓Standard Meridian 82 degrees 30' E sets IST at UTC + 5:30.
- ✓Six physical divisions - remember roof, living room, floor, desert, coasts and islands.
- ✓Rivers: Himalayan = perennial; Peninsular = seasonal; Narmada and Tapi flow west.
- ✓South-West monsoon (June-September) delivers most of India's rain.
