At a continent-continent convergence, folded mountains are produced.
Explanation:
Continental crusts tend to fold as a result they do not sub duct.
As in the case, if the two continents collided with each other for many many years, then the mass of both the continents create mountains that fold upward and the mountains those are formed by such process are called folded mountains. Example: Himalayas of Nepal, the Appalachian mountains etc.
When two continental crusts collide, earthquakes are generated due to the displacement of the tectonic plates.
