The Geology of the Himalaya is a record of the most dramatic and visible creations of modern plate tectonic forces.
The Himalayas, which stretch over 2400 km are the result of an ongoing orogeny, the result of a collision between two continental tectonic plates.
This immense mountain range was formed by huge tectonic forces and sculpted by unceasing denudation processes of weathering and erosion.
The Himalaya-Tibet region is virtually the water tower of Asia: it supplies freshwater for more than one-fifth of the world population, and it accounts for a quarter of the global sedimentatary budget.
Topographically, the belt has many superlatives: the highest rate of uplift (nearly 1 cm/year at Nanga Parbat), the highest relief (8848 m at Mt.
Everest Chomolangma), the source of some of the greatest rivers and the highest concentration of glaciers outside of the polar regions.
