|
The Gondwanaland split into a number of plates.
|
|
|
The continents of Europe and Asia were formed.
|
|
|
Sedimentary rocks accumulated in the Tethys geosyncline were folded.
|
|
|
India and Australia were formed.
|
Detailed explanation-1: -After separating from the Gondwana land, the Indo-Australian Plate drifted towards the north in the direction of the Eurasian Plate. This resulted in the collision of the two plates, and due to this collision, the sedimentary rocks in the Tethys got folded to form the mountain system of western Asia and the Himalayas.
Detailed explanation-2: -This plate boundary is called the Sumatran Subduction Trench, and it is where the oceanic Indian/Australian plate is slowly descending beneath (subducting under) the continental Eurasian plate at a rate of about 4.5 cm/year (2 inches/year).
Detailed explanation-3: -The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today.
Detailed explanation-4: -As the Indian plate is moving northward relative to the Eurasian plate and collides with it, a convergent boundary is created.
