Video: 7 facts about the Mariana Trench - the deepest on Earth
2024 Author: Seth Attwood | [email protected]. Last modified: 2023-12-16 15:55
The Mariana Trench, an underwater trench in the western Pacific Ocean, is the deepest place on earth. The depth of its lowest point - the Challenger Abyss - is 10,994 meters. Much of what is happening there has yet to be discovered by man - the enormous depth, pressure and darkness make research extremely difficult.
--------- 1 ----------
Many people think that the Challenger Abyss is named after a professor from Arthur Conan Doyle's The Lost World. In fact, Challenger II is the ship from which it was first possible to measure it with an echo sounder. In 1951, the deepest at that time was recorded - 10,899 meters.
--------- 2 ----------
The maximum depth of the Mariana Trench has not been finally established: as of 2011, it is 10,994 meters ± 40 meters. And this may well not be the final result.
--------- 3 ----------
People have visited the bottom of the Mariana Trench. Of course, in special equipment. For the first time - in 1963. And in 2012 - James Cameron.
--------- 4 ----------
The highest point on Earth - Mount Everest (Chomolungma) - rises 8848 meters above sea level. If we could lower it to the bottom of the Mariana Trench in its deepest place, there would be even more than two kilometers of water above its top.

It has its own volcano that has created an amazing rarity: a lake of molten sulfur. And hydrothermal springs, "black smokers", the water in which is very hot: measurements showed 450 degrees. It does not boil there because of the tremendous pressure. Thanks to this, unlike many deep-sea places, the water in the Mariana Trench is generally not too cold: from 1 to 4 degrees.

The pressure at the bottom is greater than at the surface - about one thousand one hundred times. But, as you know, "life is everywhere", and even these frightening depths are no exception. Molluscs, deep-sea organisms, and the most unusual and famous "inhabitants" are xenophiophores. They are remarkable not so much for their poisonousness as for their enormous size for such creatures. 10 centimeters across - and it's all in one single cage!
