Physiographic Divisions of India
India is broadly divided into six physical regions: the Northern Mountains, the Northern Plains, the Peninsular Plateau, the Indian Desert, the Coastal Plains, and the Islands.
The Northern Mountains
Dominated by the Himalayas, these young fold mountains act as a natural climatic barrier to the Indian subcontinent and are the source of major perennial rivers.
The Northern Plains
Formed by the deposition of silt from rivers like the Ganga, Brahmaputra, and Indus, these plains are highly fertile and densely populated.
The Peninsular Plateau
A triangular, tableland region rich in minerals, bordered by the Western Ghats and Eastern Ghats on either side.
Coastal Plains and Islands
Narrow coastal strips flank the peninsula, while island groups like the Andaman and Nicobar and Lakshadweep add to India's vast maritime boundaries and ecological diversity.
