Question

When an oceanic plate and a continental plate collide, what is the resulting feature?

Answer 1

oceanic plate crust is thinner and denser than continental crust, so the thinner oceanic crust gets bent and pulled under the continental crust. this creates a subtraction zone.

Answer 2

it could form a trench, or a mountain range, or one plate could subduct beneath another and the other "floating" on top.
