coninental trenches are trenches that go across countries...i think
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
Trenches are caused by plate movement.
Reserve trenches
In the Trenches was created on 2007-01-30.
Reserve trenches were used as supplies for the trenches out the front. In world war one, they had come up with a technique of hiding in trenches before they fight. To do this properly, they had made them zig-zags. The trenches on the front line were where the soldiers would fight from. Reserve trenches were used in case these people had anything happen to them and they needed to use more trenches and more men. Throughout the war, the conditions of the front line trenches became worse as the communication and reserve trenches improved. I hope that helped :)
Deep ocean trenches form
Rise
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
Continental shelf
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.
It is a passive continental margin. There is no subduction or convergence.
Treches are formed when an ocean plate subducts under a continental plate.

when two plates collide they form trenches.
Ocean trenches and Island arcs.
A continental slide is the new crust on the earth surface. It happens when two plates below the earth surfaces meets and the boundary became deep trenches.
Convergence can occur between oceanic-oceanic, oceanic-continental, and continental-continental plates. This process typically leads to the formation of mountain ranges, deep ocean trenches, and volcanic arcs.
