The Mariana Trench is the deepest part of the world's oceans, and the lowest elevation of the surface of the Earth's crust. It is currently estimated to be up to 10,971 metres (35,994 ft or 6.817 miles) deep. It is located in the western Pacific Ocean, to the east of the Mariana Islands.
what happens is the ocean floor does not just keep spreading.instead, it sinks beneath deep underwater canyons called deep- ocean trenches

It is the Abyssal plain.

At deep-ocean trenches, subduction allows part of the ocean floor to sink back into the mantle. The ocean floor does not just keep spreading. Instead, it sinks beneath deep underwater canyons called deep-ocean trenches. Where there are trenches, subduction takes place.
