A) What are the features of Himalaya mountains ?
B) Write any five features of eastern ghat and western ghat .

Dear Student,

Answer (a) 1)The Himalayas is a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau.

2)The earth is composed of several plates. In the past there was only one huge land mass or the Pangea. This Pangea broke up and drifted apart from one another. The Gondwana land was the southern part of this Pangea. Due to conventional current, this Gondwana land was further broken down and split into several parts. One part of this Gondwana, the Indo-Australian plate started drifting towards the North. As a result it collided with the Eurasian plate in the North. This collision caused the sedimentary deposition of the Tethys to get folded forming the Himalayas.

3) Himalayas are regarded to be still in youth because these have been formed in the late Cretaceous-Tertiary Period i.e. relatively recently in the earth's history, compared to older mountain ranges like the Aravallis in India, and the Appalachian in the USA. 

4) Himalayas have three parallel ranges:

  • Himadri

    The features of Himadri are:

    • It is the northern most range of Himalayas, also called the great or inner Himalayas.
    • It includes the most prominent Himalayan peaks.
    • It consists of granite.
    • Many glaciers descend from Himadri.
    • The average range of mountains found here is 6,000 metres

     

    Himachal

     

    • The altitude varies between 3,700 and 4,500 metres and the average width is of 50 Km.
    • The ranges are mainly composed of highly compressed and altered rocks.

     

    Shiwalik

    • They extend over a width of 10-50 Km and have an altitude varying between 900 and 1100 metres.
    • These ranges are composed of unconsolidated sediments brought down by rivers from the main Himalayan ranges located farther north.

For rest of the queries kindly ask in separate thread.

Regards.
