Question

The young fold mountain of India is _____.
a.The Aravalis
b.The Himalayas
c.The Satpura ranged.
d.The Vindhyan range

Answer 1

Hint: Globally, India lies in the Northern Hemisphere. India has extreme relief features. The major physiographic divisions of India are;
The Himalayas
The Indo - Gangetic plain
The Peninsular plateau
The coastal plains
The Great Indian Desert
The Islands

Complete answer:The peninsular plateau is considered to be the oldest landforms of India while the Himalayas are considered to be the recently formed landforms.
The Himalayas play an important role in the Indian subcontinent. They act as a protective barrier for India.
-The Himalayas are called young fold mountains and are formed a few million years ago.
-Fold mountains are usually formed when two or more Earth’s tectonic plates are pushed together.
-At the point of their collision, the compressing boundaries and debris are folded into rocky terrain, hills, and mountain ranges.
-These mountains were formed due to the collision of the Eurasian plates and the Indo-Australian plates due to Continental Drift.

Looking at the above options:

Option a: The Aravalli ranges are the oldest residual fold mountains. Hence, this is an incorrect option.

Option b: The Himalayan ranges are the youngest landform of the Earth. Hence, this is a correct option.

Option c: The Satpura range is a horst mountain which is flanked by the Narmada and Tapi graben. This is an incorrect option.

Option d: The Vindhyan ranges are fault black mountains that are formed from the faults evolved from the earth's crust. Hence, this is an incorrect option.

Option 'b' is correct.

Note: The young fold mountains are a result of the compressive forces involved in the collision of the two continental plates, that is, the Asian and the Australian. The Alps are an example of young fold mountains. They contribute much to the original forest cover of central and southern Europe.
