The Northern Mountains:
It stretches across northern India from Jammu and Kashmir to Arunachal Pradesh (about 2500 km) with a varying width of 240 to 320 km forming Himalaya in the East-West direction and its offshoots run in North-South direction along the India-Myanmar boundary traversing through Nagaland, Manipur and Mizoram known as eastern hills. They represent the youngest and highest folded mountains of the earth formed by the tectonic collision of the Indian plateau with the Eurasian plateau.
Longitudinally the Himalaya consist of four parallel range from South to North
ADVERTISEMENTS:
i. The outer Himalayas (Shiwalik) It is almost continuous range of low hills, composed of unconsolidated tertiary sediments emerged as most recent phase in Himalaya orogeny.
ii. The lesser Himalayas (The Himachal) It generally consists of unfossiferous sediments or metamorphosed crystalline. Important range include the Dhauladhar, Pirpanjal, Nag Tiba, Mahabharat and Mussoorie range.
iii. The Greater Himalaya (The Himadri) This is the most continuous loftiest and northern most range of Himalayas. It has a core of Archaean granites, gneisses and schist’s rocks. This range contains one of the highest mountain peaks of the world.
iv. The Trans Himalaya It is also called the Tibetan Himalaya. This range consisting of mainly Karakoram, Ladakh and Kailash range.
Purvanchal:
This is the North-Eastern Himalayas that run north to South through Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura and eastern Assam.
The Great Plains:
The Great Plains of India consists largely of alluvial deposits brought down by the rivers originating in the Himalayan and the peninsular region. They are mainly formed by the alluvial deposits of the Indus, Ganga, Brahmaputra and their tributaries.
