Ocean trenches have relatively steep sides falling to the ocean floor. Ocean trenches are typically caused when an oceanic crustal plate slides under a lighter continental plate or another oceanic plate. It is believed to work by density.Where one plate slides under another, this is called subduction.t least five trenches are over 6 miles (10 km) deep. The greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level.
Answer: The ocean's deepest area is the Mariana Trench (also called the Marianas Trench), which is about 11 km (almost 7 miles, or almost 36,000 feet) deep. The trench is 1,554 miles long and 44 miles wide, and is like the Grand Canyon of the ocean, although it is 120 times larger.Contrary to what you might picture, the trench is wide-according to NOAA, almost 5 times wider than it is deep. The Mariana Trench is located in the western North Pacific Ocean.he trench is 1,554 miles long and 44 miles wide, and is like the Grand Canyon of the ocean, although it is 120 times larger.
