Question

The Himalaya was being formed with the folding of sediments which were deposited in the ______ sea.
A: Tethys
B: Arabian
C: Caspian
D: South China

Answer 1

Hint: The Himalayas are very popular as the young fold mountains. This is because of the facts like: These were formed a few million years ago. Fold Mountains are formed while two or more of the Earth’s tectonic plates are pushed together.

Complete answer: The Tethys Himalaya i.e. TH is the approximately 100-km wide synclinorium. These are formed by strongly folded and imbricated, weakly metamorphosed sedimentary series.
The Tethys Ocean was the ocean which existed between the continents of Gondwana and Laurasia. These existed during much of the Mesozoic era, before the opening of the Indian and Atlantic oceans. It was during the Cretaceous period. These are also referred to as the Tethys Sea of Neotethys.

Additional Information:
At this point of collision between the plates, the compressing boundaries, rocks and debris are warped. And hence these are folded into rocky outcrops, hills, mountains, and the entire mountain ranges. These mountains were being formed because of the folding of the earth’s crust. This was due to the tectonic activity of the Fold Mountains. These mountains are formed when two tectonic plates collide with one another. These are formed due to the collision of the Eurasian plates and the Indo-Australian plates due to Continental Drift.

Thus, The correct option is A.

Note: Some facts are:
-Himalayan Region is in the shape of the arc.
-Himalayan Region is composed of the sedimentary rocks.
-In the Himalayan Region, normally the height of Mountain peaks is approximately 6000 metres.
-It is the northernmost and in a continuous range.
-By nature these are symmetrical and have granite.
