17 interesting facts about the Mariana Trench

Of course, the Earth has not yet been thoroughly studied by us, but we already know that the Mariana Trench is the deepest place in the world’s oceans. However, the degree of study of the sea depths as a whole leaves much to be desired, and we do not even know what is happening at a depth of hundreds of meters. What can we say about many kilometers? After all, it is possible that somewhere, deep below, under the monstrous pressure of the water column, there is also life, strange, unusual and incomprehensible to us.

Interesting facts about the Mariana Trench

  1. Recent studies have found that in depth it does not reach the round figure of 11 km, only some 6 meters.
