Answer 1

1. The three parallel ranges of the Himalayas are the Himadri, the Himachal and the Shiwaliks. The Himachal range lies towards the south of the Himadri. The range is also known as the Lesser Himalayas. A lot of hill stations are located in this range. Some of them are Nanital, Shimla, Mussoorie, Dehradun, Kullu and Manali.


2. The Purvanchal range is found on the eastern part of the Indian territory. It is made up of soft rocks, mud and silt. Hence, it is more prone to landslides. It comprises the following low hills:

• Patkai Bum and Naga hills in the north
• Garo, Khasi and Jantia in the centre
• Mizo hills towards the south

3. The Great Indian Desert lies in the western part of the country in Rajasthan. It is also known as the Rajasthan Desert. It is the region with very less humidity and rainfall. Also, it is the only area in India that witnesses inland drainage.

4. The Northern Plains of the Indian territory are drained by several rivers. Most of the area is drained by the River Ganga. The silt brought by the river has made the soil in these plains very fertile. Hence, agriculture is the major occupation of the people living in these plains. The Ganga Basin covers the states of Haryana, Rajasthan, Uttar Pradesh, Bihar, Madhya Pradesh and West Bengal.


5. The Peninsular Plateau is divided by the River Narmada into two parts: the Deccan Plateau and the Central Highlands. The Central Highlands comprise plateaus made of igneous rocks. The rivers flowing from these highlands join the rivers Yamuna and Ganga from the southern direction.
