Trenches are formed at convergent plate boundaries involving at least one oceanic plate, where the more dense plate subducts under the less dense plate.

How are mountains chains formed?

When two edges of tectonic plates collide (convergent boundary) they can cause a crumpling effect and an upthrust to form mountains. The Himalayas, for instance, were formed when the Indian Plate crashed into the Asian Plate. Convergent boundary also applies to the situation where one plate moves under the other (subduction) this kind of plate boundary can also form mountain chains. An example of this is the Andes mountains.
