Mountain formation most commonly results when two continental tectonic plates collide , causing Earth’s crust to crumple, fold, and uplift into mountain ranges such as the Himalayas.

Quick Scoop

  • When two continental plates press together at a convergent boundary, the rock layers buckle and fold upward into tall ranges called fold mountains.
  • This collision-driven uplift is the classic mechanism behind many of the world’s highest and longest mountain chains.

In a typical multiple‑choice context, the correct option is the one describing collision of continental plates (or convergence of tectonic plates to uplift the crust), not just any random plate interaction like two oceanic plates colliding alone.
