The Himalaya is the highest mountain range in the world. It stretches from Kashmir in eastern Asia to Bhutan in western Asia. Eight of its mountains rise to over 8,000 metres (26,250 feet). This includes Mount Everest, the highest mountain in the world at 8,848 metres (29,035 feet). The Himalaya were formed when two plates of the earthâ€(tm)s crust, the Eurasian and Indo-Australian plates, collided. This forced the earthâ€(tm)s crust to be pushed up into mountains. The Himalaya are currently estimated to be rising in height at a rate of around 4mm (over 0.1 inches) a year.
