What type of plate boundary formed the Himalayas when the Indian Plate collided with the Eurasian Plate?

The Himalayas formed at a convergent boundary when the Indian Plate collided with the Eurasian Plate.

The Indian Plate began moving northward after separating from Gondwana and eventually encountered Eurasia. Because both plates carried continental crust, neither easily sank into the mantle. Instead, compression shortened, folded, and thickened the crust, raising the Himalayan mountain system and the Tibetan Plateau.

This collision remains active. The Indian Plate continues to move northward, so the region experiences frequent earthquakes and ongoing uplift. Earthquakes in Nepal, northern India, Bhutan, and southern Tibet reflect continuing strain along major thrust faults.

A convergent boundary is broader than a subduction zone. Oceanic–continental and oceanic–oceanic convergence commonly involve one plate descending beneath another, but the India–Eurasia collision is primarily a continent–continent collision. The Himalayas are therefore not an example of a divergent or transform boundary.
