CITAZIONEQuesto non credo, perchè bisogna sempre ragionare in termini di popolazione e non di singoli individui. Una popolazione stabile di "polpi in grado di distruggere una nave" penso si noterebbe...
tu dici? XD e invece città sottomarine umane e non?CITAZIONEDovrei approfondire. Wikipedia (in inglese) che dice?
The Mariana Trench is part of the Izu-Bonin-Mariana Arc convergent boundary system that forms the boundary between two tectonic plates. In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., is drawn under and downward) beneath the smaller Mariana Plate that lies to the west. Because the Pacific plate is the largest of all the tectonic plates on Earth, crustal material at its western edge has had a long time since formation (up to 170 million years) to compact and become very dense; hence its great height-difference relative to the higher-riding Mariana Plate, at the point where the Pacific Plate crust is subducted. This deep area at the plate boundary, is the Mariana Trench proper.
The movement of the Pacific and Mariana plates is also indirectly responsible for the formation of the Mariana Islands. These volcanic islands are caused by steam pressure from the boiling of water that is trapped in minerals in the Pacific Plate, where the water is superheated as it descends to hotter depths below the Mariana Plate.
dice anche che potrebbe essere un deposito di scorie nucleari e un sito di test... mutanti arriviamo! XD.
