The Mariana trench is the deepest known oceanic floor - at a maximum known depth of 36,070 feet (+/- 130 feet).
Mariana trench
The deepest known portion of the ocean floor is called the Challenger Deep, located in the Mariana Trench in the western Pacific Ocean. It reaches a depth of approximately 36,201 feet (11,034 meters) below sea level.

The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone. These areas are called deep sea trenches and the Challenger Deep in the Mariana Trench in the Pacific is the deepest known point in Earth's oceans.
deepest part of the ocean floor called the abyssal plains.
The Pacific Ocean has the deepest trenches.
Elongated troughs on the ocean floor are called oceanic trenches. These features are formed by the subduction of one tectonic plate beneath another, creating deep depressions in the seabed. Oceanic trenches are some of the deepest parts of the Earth's crust.
A deep-ocean trench is a long, narrow depression in the ocean floor where tectonic plates are being pulled into the Earth's mantle in a process called subduction. These trenches are some of the deepest parts of the ocean and are typically associated with intense seismic activity and volcanic processes.
