The Mariana Trench (sometimes called Marianas Trench) is a mysterious and extremely deep oceanic trench. Plunging deeper than Mount Everest is tall and stretching five times longer than the Grand Canyon, the Mariana Trench is the deepest place on Earth (that we currently know of).

Despite advancements in technology and seabed mapping, a large part of the ocean floor remains unexplored. In fact, more people have been to the moon than to the bottom of the Mariana Trench.
