Physical Divisions of India
India is divided into six major physical regions: the Northern Mountains (Himalayas), the Northern Plains, the Indian Desert, the Peninsular Plateau, the Coastal Plains, and the Islands.
The Northern Mountains (Himalayas)
Acting as a natural sentinel in the north, the Himalayas contain some of the highest mountain peaks in the world and protect India from cold freezing winds from Central Asia.
The Northern Plains
Formed by the alluvial deposits brought down by the Indus, Ganga, and Brahmaputra river systems, these plains are highly fertile and densely populated.
The Peninsular Plateau
A triangular tableland comprising rich mineral deposits, bordered by the Western Ghats and Eastern Ghats, with the Deccan Plateau at its heart.
Coastal Plains and Islands
Narrow coastal strips flank the Peninsular plateau along the Arabian Sea and the Bay of Bengal, complemented by island groups like Lakshadweep and Andaman & Nicobar.
