The Mariana Trench is located in the south west of the island of Guam, the largest of the Mariana Islands in the west of the Great Ocean, and is right in the middle of Japan and Indonesia. It's the deepest point in the world. As a result of the research conducted by scientists, the deepest point was determined to be 10,994 meters and its length was 2542 kilometers. The width of the pit is 69 kilometers.
To explain how the Mariana trench was formed; Sometimes some of the plates that make up the Earth's crust collide by approaching each other. As a result of this collision, one of the plates enters the bottom of the other and performs a situation called "plunge".
The meaning of the plunge situation is that the plate, which is superior in intensity, is the phenomenon of shifting under the less dense plate. As a result, severe earthquakes can be seen in these areas, and the depths of earthquakes are 700 kilometers depending on the size of the sheets. Here in the Mariana Trench is a pit formed by the Pacific Plate and the Mariana plate bumping into each other.
The people who first landed in this very large depth of nature were American military Lieutenant Donald Walsh and Swiss scientist Jacques Piccard. In order to perform the dive, they used a vehicle that can dive under the water called BATISKAF (a steel globe shaped of hard material that can withstand very high pressures, draining gasoline for diving and taking seawater instead of the iron ballast vehicle). The dive lasted for 5 hours and landed at a depth of 10916 meters. On March 25, 2012, the director of famous films such as Titanic, Terminator, Aliens and Avatar, and also produced by James Cameron, managed to go down to the floor at 156 minutes with his own private submarine, and at this depth he made hours At the end of the ongoing research, he completed his adventure with an upward-exit journey of 70 minutes.
Although these journeys towards the depths of the Mariana trench are overcome with no accidents and no trouble, the dangers of breast strain and ignored are quite large, because the pressure at the bottom point is almost 1000 times the surface pressure of the ground. James Cameron's diving submarine was made for this reason as resistant to a pressure that could occur more than 7250 tonnes per square metre. The pressure in the ocean increases to inch in 1 kilogram every 10 meters. Given this example, it is clearly understandable that no man can land in such depths without the help and improved tool and similar equipment.
