Which boundary interaction is

The boundary interaction responsible for forming mountains on continental plates is the convergent plate boundary interaction. At convergent boundaries, two tectonic plates move toward each other, and when both plates are continental, they can collide, causing the crust to buckle and fold, which leads to the formation of mountain ranges. An example of this is the Himalayas, which were formed by the collision between the Indian Plate and the Eurasian Plate.
