What is the deepest part of the ocean?

The deepest part of the ocean is the Challenger Deep, located in the Mariana Trench in the western Pacific Ocean. It reaches a depth of approximately 10,984 metres (36,037 feet). This extreme depth is a result of the subduction of the Pacific Plate beneath the Mariana Plate. The conditions at Challenger Deep are harsh, with immense pressure, low temperatures, and complete darkness. Despite these conditions, unique organisms, such as deep-sea fish and microorganisms, have adapted to survive in this environment.
