The deepest point on Earth is called the Mariana Trench, specifically the Challenger Deep, which reaches a depth of about 36,000 feet (over 10,900 meters). Located in the western Pacific Ocean, east of the Mariana Islands, the trench was formed by the subduction of one tectonic plate beneath another. The extreme depths create unique environmental conditions, including high pressure, low temperatures, and complete darkness. Despite these harsh conditions, extraordinary life forms have adapted to thrive in this abyss, making the Mariana Trench a focus of scientific study and exploration. Its depth represents a fascinating frontier in oceanography.
