Major Physiographic Divisions
The physical features of India are grouped under the following physiographic divisions:
The Himalayan Mountains
The Northern Plains
The Peninsular Plateau
The Indian Desert
The Coastal Plains
The Islands
Let’s discuss each of them in detail:
The Himalayan Mountains
Himalayan mountains are stretched over the northern borders of India. These mountain ranges run in a west-east direction from the Indus to the Brahmaputra. The Himalaya consists of 3 parallel ranges in its longitudinal extent.The northern-most range is known as the Great or Inner Himalayas or the Himadri. It is the most continuous range consisting of the loftiest peaks with an average height of 6,000 metres.
The folds of the Great Himalayas are asymmetrical in nature. The core of this part of Himalayas is composed of granite.
The range lying to the south of the Himadri forms the most rugged mountain system and is known as Himachal or lesser Himalaya.
Pir Panjal range forms the longest and the most important range.
The outermost range of the Himalayas is called the Shiwaliks. These ranges are composed of unconsolidated sediments.
The longitudinal valley lying between lesser Himalaya and the Shiwaliks are known as Duns. Dehra Dun, Kotli Dun and Patli Dun are some of the well-known Duns.The Himalayas have also been divided on the basis of regions from west to east.
The mountains are the major sources of water and forest wealth.
The northern plains are the granaries of the country. They provide the base for early civilisations.
The plateau is a storehouse of minerals, which has played a crucial role in the industrialisation of India.
The coastal region and island groups provide sites for fishing and port activities.
