The Mariana Trench is the deepest trench in the ocean. It is located in the western Pacific Ocean, 200 kilometres east from the Mariana Islands. It is crescent shaped and is all together 5,238 kilometres squared without counting the depth. The deepest depth that is known by us is 10,984 metres. It is known as challenger deep because, the ship that found it was called the Challenger. It was measuring the depth of the sea with a long rope, then when it got to the Mariana Trench (they didn’t know about it back then), it used all of the rope. Anyone who tries to go down the trench will either want to go up or too late, they are squeezed to death by the pressure. Also, there are mud volcanoes coming from it. When the underwater mud volcanoes erupt, they release gas, mud and water. There are at least 10 currently active volcanoes leading from the giant trench.
