Answer 1

Answer:

Northern Mountains, Purvunchal, Peninsular Plateau

Explanation:

Northern Mountains:

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.

Purvunchal:

This is the North-Eastern Himalayas that run north to South through Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura and eastern Assam.   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.

Peninsular Plateau:

It covers an area of about 16 lakh sq km forms the largest and oldest physiographic division of India. It is bounded by the Aravallis in the North-West, Maikal range in the North, Hazaribagh and Rajmahal Hills in the North-East, the Western Ghats in the West, and the Eastern Ghats in the East.

To the South the coastline is more rugged. It is called the Konkan Coast up to Goa and from there onwards in Karnataka, it is the Kanara Coast, further South the part that lies in Kerala is called Malabar Coast till Kanyakumari, the southern tip of the Indian mainland.

The East coastal plain is broader and more continuous than the West coastal plain and lies between the Eastern Ghats and the Bay of Bengal. A major part of the eastern Coastal Plains is covered by the deltaic deposits of rivers Mahanadi, Godavari, Krishna and Cauvery. It is called northern Circars between Mahanadi and Krishna rivers and Coromandel Coast South of the Cauveri up to the southernmost tip of the Indian mainland.
