An oceanic trench is a deep canyon on the ocean floor. Back in 1977 a very interesting discovery was made on the deep ocean floor where no light penetrates.
This is caused by two plates pulling apart. While most life on this planet requires sunlight to live there is an. The canyon is located near the 100 meter isobath on the continental shelf and is 2 2 km 1 4 mi deep at the base of the continental slope. As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.
It is the largest known ocean canyon off the east coast of the united states and one of the largest submarine canyons in the world. The shifting plates may collide converge move away diverge or slide past transform each other. It lies from 3 to 6 kilometers 1 9 to 3 7 miles below the surface.

The oceans floor doesn t just keep getting wider instead the ocean floor plunges into deep underwater canyons called deepocean trenches where ever deep ocean trenches are there is subduction. I think its called either an abyss or a sea trench. The ocean floor has the same general character as the land areas of the world. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on.
Over an 80 km 50 mi distance the average slope of the canyon floor is. Trenches occur where one tectonic plate subducts under another. A submarine canyon is a steep sided valley cut into the seabed of the continental slope sometimes extending well onto the continental shelf having nearly vertical walls and occasionally having canyon wall heights of up to 5 km from canyon floor to canyon rim as with the great bahama canyon. Mountains plains channels canyons exposed rocks and sediment covered areas.
The abyssal plain forms much of the floor under the open ocean. A deep canyon in the ocean floor is called. What is the deep canyon on the ocean floor. It has a steep slope with a sharp drop to the deep ocean floor.
Many ocean floor features are a result of the interactions that occur at the edges of these plates.
