Trenches are deep trenches at the bottom of the ocean. For humans, many of them are still unknown because some of them are too deep for humans to reach the bottom. What is the name of the deepest trench in the world? Let’s get to know.
The Mariana Trench is 2550 km long and curved, with an average width of 70 km. It has been verified by scientists that this trench has been formed for 60 million years.
The deepest part of the Mariana Trench is 6 to 11 kilometers, which is the deepest part of the ocean currently known. The water there is high pressure, complete darkness, low temperature, and extremely low oxygen content. It is one of the harshest areas on earth.
For the formation of the Mariana Trench, many people believe that it was formed by the collision between the ocean plate and the continental plate. Because of the high density and low location of the ocean plate rocks, the ocean plate subducted and inserted under the continental plate, and the plate gradually melted and disappeared after entering the mantle. A trench will be formed at the place of collision.
In January 1960, scientists first successfully dived to the bottom of the Mariana trench in a deep-sea submersible. The bottom of the trench is up to 1,100 atmospheres.
The usual temperature in the Mariana Trench is only 2℃. But at these depths, scientists found flounder and small red shrimp swimming.
