Physical divisions
| Division | Features |
|---|---|
| The Himalayas | Young fold mountains in the north, with the Himadri, Himachal and Shiwalik ranges |
| The Northern Plains | Fertile land built by the Indus, Ganga and Brahmaputra |
| The Peninsular Plateau | Old hard rocks, with the Deccan Plateau and the Western and Eastern Ghats |
| The Indian Desert | Dry land in the west, to the west of the Aravalli hills |
| The Coastal Plains | Narrow strips on the west and wider ones on the east |
| The Islands | Lakshadweep in the Arabian Sea; Andaman and Nicobar in the Bay of Bengal |
Rivers
Himalayan rivers such as the Ganga, Indus and Brahmaputra are perennial, fed by rain and melting snow. Peninsular rivers such as the Godavari, Krishna and Kaveri flow mainly in the rainy season. Most peninsular rivers flow east into the Bay of Bengal, but the Narmada and Tapti flow west into the Arabian Sea.
Himalayas or Ghats.
Plains or plateau.

Farming, power, cities.
Why does location matter?
The Indian Ocean gave India sea routes with Africa, West Asia, Southeast Asia and Europe. The Himalayas shield the country from cold winds from the north. India's mountains, rivers and coasts support farming and trade.
Worked examples and common mistakes
Example: Which line of latitude passes through India? The Tropic of Cancer. Example: Which rivers flow west? The Narmada and the Tapti. Common mistakes: thinking that all peninsular rivers flow west, and saying that the Himalayas are old. They are young fold mountains.
