Question

describe how Himalaya mountain were formed ???

Answer 1

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.

Answer 2

The world's tallest mountain ranges formwhen pieces of Earth's crust—called plates—smash against each other in a process called plate tectonics, and buckle up like the hood of a car in a head-on collision. ... Thirty of the world's highest mountains are in the Himalaya.
