|  The Himalayas include over a hundred mountains exceeding 7,200 metres (23,600 ft) in height.  By contrast, the highest peak outside Asia--Aconcagua, in the Andes-- is 6,961 metres (22,838 ft) tall. According to the modern theory of plate tectonics, their formation is a result of a continental collision or orogeny along the convergent boundary between the Indo-Australian Plate and the Eurasian Plate abut 50 million years ago. So the Himalayas are among the youngest mountain ranges on the planet.
