when two plates collide they form trenches.
Yes
Subduction (where one plate is forced beneath another less dense plate - may occur at oceanic-oceanic and oceanic-continental boundaries), obduction (where oceanic plate is forced over a continental plate) and orogenesis where two continental plates collide and mountains are formed (e.g. the Himalayas).
The oceanic plate goes under the continental plate and into the mantle in a process known as subduction. This results in the formation of mountains and volcanoes on the continental plate.
The Himalayas are formed from a continental to continental plate convergence.
A convergent boundary between an oceanic plate and a continental plate.
The Andes Mountains in western South America are a result of an oceanic-continental convergence of lithospheric plates. It would occur anywhere that an oceanic plate and a continental plate are moving toward each other.
When two continental plates collide or a continental plate collides with an oceanic plate.
