EVOLUTION OF INDIA

Image
ssc preparation, important competetion questions, current affairs of india, latest question asked in competetion papers, EVOLUTION OF INDIA The Indian craton was once part of  the Supercontinent of Pangaea .  At that time, it was attached to Madagascar and southern Africa on the south west coast, and Australia along the east coast. During the Jurassic Period, rifting caused Pangaea to break apart into two supercontinents namely,  Gondwana (to the south)  and  Laurasia (to the north). The Indian craton remained attached to  Gondwana , until the Supercontinent began to rift apart about in the early  Cretaceous. The Indian Plate then drifted northward towards the Eurasian Plate. This orogeny, which is continuing today, is related to closure of the  Tethys Ocean .  The closure of this ocean, which created the Alps in Europe, and the Caucasus, range in western Asia, created Himalaya Mountains and the Tibetan Plateau in South Asia. The current organic event is
