An oceanic crust and a continental crust collide, which plate will be sub-ducted and why?
The oceanic crust will subduct under the continental crust because it is more dense.

Two oceanic plates collide, one slides under the other. What geologic event would this cause?
Continental Rift
Mid-Ocean Ridge
Oceanic Trench
Chain of Volcanoes
15
What is the theory of plate tectonics?
The theory that parts of the crust and upper mantle are broken into sections that can move and interact with each other to cause geologic events and structures.
