Marianas Trench

The Mariana Trench is the deepest part of the world's oceans, located in the western Pacific Ocean near the Mariana Islands. It stretches over 1,550 miles and reaches a maximum depth of about 36,070 feet (10,994 meters) at the Challenger Deep. This extreme depth creates high pressure, cold temperatures, and complete darkness, making it a challenging environment for exploration. Despite these conditions, scientists study the trench to learn about deep-sea ecosystems, geology, and the Earth's structure, revealing unique forms of life adapted to this extreme habitat.
