Question

The Himalayan mountain system belongs to which of the following?
A.Fold mountains
B.Volcanic mountains
C.Block mountains
D.Glacier mountains

Answer 1

Hint: The Himalayan mountain system is created when two or more tectonic plates of the earth are pushed together. The debris and rocks are folded and wrapped into mountain ranges and hills at these compressing and colliding boundaries.

Complete answer:
 Fold mountains are formed when the horizontal layers of sediments that are deposited on the sea bed are folded and squeezed when subjected from both sides to the force of compression. They get uplifted gradually and thus, result in the formation of extensive fold mountains. Formed in the recent ages, the great Himalayas, the Rockies, the Andes and the Alps are all young uplift fold mountains. The Urals, The Aravali and the Appalachians are the old fold mountains. They have rounded peaks and are low in height, whereas the young fold mountain peaks are sharp pointed and very high. The Himalayan mountain is one such example of the young fold mountain that began to form when Indian plate and Eurasian plate, two large land masses collided due to plate movement, around 40 to 50 million years ago. Most of the mountain peaks are covered with snow and glaciers, which is one of the common features of many mountain slopes. Perennial rivers also rise from these glaciers.The Himalayan mountain system belongs to fold mountains.

Hence, the correct answer is option (A).

Note: Mountains are generally stretched over hundreds of kilometers as a long chain that are called ranges. Snow fields or snow caps also occur that are those mountain peaks which are covered with snow permanently.
