Where is the Mariana Trench

Where is the Mariana Trench?

The Mariana Trench (or the Marian Trench)is a trough in the earth's crust in the shape of a crescent, a size of 2550 by 69 km. This is the deepest place on Earth (about 11 thousand kilometers!). There is a depression in the western part of the Pacific Ocean near the Mariana Islands, which gave it its name.

Below is a detailed description of the Mariana Trench and its distinctive features.

The uniqueness of the cavity

Few people decide to sink to the ocean floor in this place, since in the Mariana Trench the water pressure exceeds the pressure in other places of the ocean by about a thousand times.

The water temperature in the trough varies from 1 to 4degrees of heat. In addition, there is a large number of hydrothermal sources (differently, "black smokers"), from which water reaches a temperature of 450 ° C.

Because of the strong pressures of water, all living things in thethis part of the sea are doomed to extinction. But at the beginning of the 21st century near the serpentine accumulations living organisms (mollusks) were found that could survive in such conditions.

In addition, liquid carbon dioxide was detected here. The Mariana Trench is the only such underwater area called Champagne (in honor of the bubbles that break out of the water).

Dirt or mucus is a habitual cover of the bottom of the cavity. Due to the fact that the pressure does not allow the remains of animals and plankton to go up, everything remains at the bottom of the ocean, turning into a mud of gray-yellow color. Sand in the trench is practically absent.

The deepest point of the Mariana Trench is the "Challenger's Abyss".
