The formation of the Himalayas is considered to be associated with which process?

Correct answer: Collision of plates

The Himalayas were formed mainly through the convergence and collision of the Indian Plate with the Eurasian Plate. As the Indian Plate moved northward, its continental crust pressed against the Eurasian continental crust. Because continental crust is relatively buoyant, it did not simply sink; instead, the sediments and rocks were compressed, folded and uplifted, producing a young fold mountain system. Sea waves, river deposition and sandstorms can shape or modify landforms, but they cannot account for the enormous height, length and folded structure of the Himalayas. Thus, plate collision is the governing geological process, making option A correct.
