The Mariana Trench is located in the western Pacific Ocean at approximately 124 miles from the Mariana Islands. It's a crescent-shaped scar in the earth's crust and measures 1500 miles long and 43 miles wide. The trench's deepest point is called the Challenger Deep. It's considered the deepest point of our planet. The distance between the Challenger Deep and the surface of the ocean is roughly 7 miles. The Mariana Trench was formed due to the collision of converging plates of oceanic lithosphere. The high pressure at the seabed causes an increase of water density by 4.96% at the bottom of the trench.
