Physiographic Divisions
India is broadly divided into six physical regions: the Himalayas, the Northern Plains, the Peninsular Plateau, the Indian Desert, the Coastal Plains, and the Islands.
The Northern Plains
Formed by the alluvial deposits of the Indus, Ganga, and Brahmaputra river systems, these plains are very fertile and densely populated, often called the 'Food Bowl of India'.
The Peninsular Plateau
A tableland composed of old crystalline rocks, rich in minerals, and bordered by the Western and Eastern Ghats on its sides.
The Thar Desert
Also known as the Great Indian Desert, located in the western part of India, characterized by arid climate, sandy soil, and scanty vegetation.
Coastal Plains and Islands
Narrow strips of flat land flanking the Arabian Sea and Bay of Bengal, along with island groups like Lakshadweep and Andaman & Nicobar, add to India's unique coastline diversity.
