The Mariana Trench is known for its exceptional depth and length, making it the deepest part of the world's oceans. Located in the western Pacific Ocean, it reaches a maximum known depth of approximately 36,000 feet (11,000 meters). The trench is of great scientific interest due to its extreme conditions, which support unique ecosystems and organisms that have adapted to survive in such an environment. Understanding the trench deepens our knowledge of marine biology and the geological processes of the Earth.
