The Himalayas is a convergent boundary mountain range. The theory behind the beginning of the Himalayas is that the Indo-Australian plate shifted into the Eurasian plate and crumpled together to form one of the youngest mountain ranges in the world. As long as it spans and high as the peaks reach, the Himalayas are still forming and growing. The Himalayas are currently moving about 67mm north a year and will rise about 5mm per year. I think that in about ten million years the Himalayas will shove up hundreds of miles into Asia and grow even higher to dwarf the size of Everest. Even further into the future I expect the continents to reverse their drift causing India to separate from Asia and to collide with South America and Antarctica.
