Unlike deep sea trenches which are found in areas where one tectonic plate slides beneath another undersea canyons are found along the slopes of most continental margins the submarine canyons for example tend to have steeper side slopes much higher gradients and considerably narrower floors. thats how they different
They are both giant holes in the ground. Trenches are found underwater and valleys are found on land.

coninental trenches are trenches that go across countries...i think
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 :)

They are narrow trenches or small, narrow valleys.
Trench. I believe they are known as trenches.
They are called oceanic trenches.
The Marianas Trench, and many other deep undersea valleys, can be found on the ocean floor.
Yes the ocean floor has mountains and deep trenches.
