Explanation:
1.Three major geographical entities, the Himadri (greater Himalaya), Himanchal (lesser Himalaya) and the Shiwaliks (outer Himalaya) extending almost uninterrupted throughout its length, are separated by major geological fault lines.
2.The silt deposited by river Ganga and its tributary makes the plain fertile. northern plain fertile because when the river ganga flow there it cannot carry so much silt with it so it deposits it on the bank so they are fertile since they carry alluvium with them . Thus the northern plains are very fertile.
3.Himalayas have been divided on the basis of regions from west to east or east to west. The division has been done on the basis of the rivers flowing in the Himalayan regions. Following is the division in east-west direction : Assam Himalayas: This part of Himalaya lies between the Tista and Dihang rivers.
4.Plateau can be defined as an area of raised land that is flat on top. Plateaus are often by themselves with no neighbouring plateau. The Malwa plateau lies between Aravali and Vindhya ranges. The Malwa Plateau basically refers to the volcanic upland north of the Vindhya Range. The Malwa region comprised a unique and separate political unit since the time of the ancient Malava Kingdom. The traditions in this region is mainly influenced by Rajasthani culture
5.The chain of mountains north of India. 1. They give rise to a large number of rivers for irrigation. 2. It blocks chilly winds from Siberia and also moisture bearing winds, causing rainfall.
6.
The different physiographic divisions highlight the unique features of each region.
(i) The mountains are the major sources of water and forest wealth.
(ii) The northern plains are the granaries of the country. They have provided the base for early civilizations.
(iii) The plateau is a storehouse of minerals, which has played an important role in the industrialization of the country.
(iv) The coastal region and island groups provide sites for fishing and port activities

Answer:
1. Himadri, Himachal, shiwaliks
The silt deposited by river ganga and its tributary makes the plain fertile. northern plain fertile because when the river ganga flow there it cannot carry so much silt with it so it deposits it on the bank so they are fertile since they carry aluvium with Thus the northern plains are very fertile.
2.Himalayas have been divided on the basis of regions from west to east or east to west. The division has been done on the basis of the rivers flowing in the himalayan regions.
3. The Malwa Plateau lies between the Aravali hills and the Vindhya range. The Aravali hills lie to the west of the plateau and the Vindhya range lies to its south. The part of the peninsular plateau lying to the north of the Narmada river, covering a major area of the Malwa plateau, is known as the Central Highlands.
4. The Great Himalayas are basically the young fold mountains that have come into existence because of convection currents and compressional forces. The mountains are the highest mountain ranges of the World.
1.They gives rise to a large number of rivers for irrigation
2.It blocks chilly winds from siberia and also moisture bearing winds, causing rainfall.
5.) (i) Each region
complements the other and makes the country richer in its natural
resources. (ii) The northern
mountains are the major source of water and forest wealth. (iii) The northern plains are the granaries of the country. They provided abase for early civilisations. (iv) The plateau is a storehouse of minerals, which has played a crucial role in the industrialisation of the country. (v) The coastal regions and island groups provide sites for fishing and port activities. Thus, the diverse physical features of the land have immense future possibilities of development.
