3. The diverse physical features of India are of immense value’.
Justify the statement by giving suitable examples.
4. Describe the “Theory of Plate Tectonics”.
5. Which range of the Himalayas has hill stations? Give some examples.​

Answer 1

Explanation:

1) This plateau consists of two broad divisions, namely, the Central Highlands and the Deccan Plateau. 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.

2) himadri range- 1. it is the northern most range of himalayas and also known as inner or greater himalayas. 2. the average height of the mountains is around 6000 meters 3. this is home to loftiest mountains.

shivalik range- 1. it is the outermost range of himalayas and also known as outer himalayas. 2. the average altitude is around 900-100 meters above sea level. 3. it is home to flat floored structural valleys called duns.

3) 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.

4) The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

5) The lesser Himalayas , 3. The Great Himalayas and Zanskar range . There are many hill picturesque for example Dhauladhar , Shimla hills, Pir panjal , Rohtang Pass , Kangla , Bara Lacha , Parang , Pin Parbati, Kinnaur and many more.

Answer 2

Answer:

1. The plateau has broad and shallow valleys and rounded hills. This plateau consists of two broad divisions, namely, the Central Highlands and the Deccan Plateau. 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.
2. 1) It is the outermost range of Himalayas. 2) Its height varies between 900 and 1100 metres. 3) These ranges are composed of unconsolidated sediments brought down by river from the main Himalayan ranges located farther north.
3. The mountains in the northern part of the country are abundant in water and forest resources while the plains are full of granaries. The plateau in central India has paved way for various industries owing to its rich mineral content and has led to the overall development of the country.
4. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. The lithosphere includes the crust and outer part of the mantle.
5. The Himachal range, in the northern Indian state of Himachal Pradesh, is the region of the Himalayan Mountains that is the most popular for hill.
