Formation of the Himalayas:

The Himalayas are the world’s tallest mountain range. Millions of years ago, here were no mountain peaks. Around 220 million years ago when Pangea was breaking apart, India started moving northward. Pangea broke into two parts Laurasia (northern part) and Gondwana (southern part). Later, convectional currents fractured the crust of Gondwanaland into a number of plates. One of the cracked plates called Indo-Australian plate drifted towards the north and collided with much larger Eurasian plate. This collision resulted in accumulation of sedimentary rocks in the geosynclines also known as Tethys, which were folded and elevated to form the mountain system of Western Asia and Himalayas.
