What Is A Deep Canyon In The Ocean Floor

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.

What is a deep canyon in the ocean floor.

Over an 80 km 50 mi distance the average slope of the canyon floor is. A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. Back in 1977 a very interesting discovery was made on the deep ocean floor where no light penetrates. Much of it is flat.

It has a steep slope with a sharp drop to the deep ocean floor. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on. 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.

While most life on this planet requires sunlight to live there is an. It lies from 3 to 6 kilometers 1 9 to 3 7 miles below the surface. Exploration of the seafloor and the earth s crust.

Many ocean floor features are a result of the interactions that occur at the edges of these plates. The shifting plates may collide converge move away diverge or slide past transform each other. A deep canyon in the ocean floor is called. Trenches occur where one tectonic plate subducts under another.

As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.
