The Mariana Trench (sometimes called the Mariana Trench) is a mysterious and incredibly deep ocean trench. It extends below the level of Mount Everest and is five times longer than the Grand Canyon, making it the deepest place on Earth (that is currently known).
Despite technological advances and improvements in mapping the deep sea, much of the ocean floor remains unexplored. In fact, more people have walked on the moon than have walked in the Mariana Trench.
This is because the conditions in the Mariana Trench are extremely harsh. Sunlight does not penetrate to such depths, so it is constantly dark, the temperature is around freezing, and the pressure is so great that it can crush people and most man-made equipment.
