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.
About 71% of the Earth's surface is covered by water, with the majority of the Earth's surface below sea level being the ocean floor. Specifically, approximately 90% of the Earth's total surface area that lies below sea level is made up of oceanic basins, while the remaining part consists of features like rift valleys and other landforms. Thus, a significant portion of the Earth's surface below sea level consists of the ocean floor.
