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 Himalayas
The young fold mountains in the northern border of India that act as a climatic barrier and are the source of major perennial rivers like the Ganga and Brahmaputra.
Northern Plains
Formed by the deposition of silt by rivers like the Ganga, Brahmaputra, and Indus, these plains are highly fertile and densely populated, serving as the food bowl of India.
Peninsular Plateau
A triangular tableland lying to the south of the northern plains, rich in minerals and bordered by the Western and Eastern Ghats.
Coastal Plains and Islands
Narrow strips of flat land flanking the peninsular plateau along the Arabian Sea and Bay of Bengal, along with island groups like Andaman and Nicobar, and Lakshadweep.
