Yes, it will crush you
The pressure of the water beyond a certain depth will collapse the vehicle--its crush depth-- we go down there in. Modern submarines may go down to almost 1,000 feet. In 1960, the Bathyscaphe Trieste descended to the bottom of the Mariana Trench near Guam, at 35,798 feet. Other than that, the closer to the crust, the hotter the water is.
The deepest trench is marianas trench and no.
No, all bodies of water have to have a bottom or else they'd go right through the earth. Some areas of the ocean, or ocean trenches, are extremely deep, with the Mariana Trench having a depth of 11km
You can pass over it in a ship but to go to the sea floor in it you need a special bathysphere.

Mariana Vincenti goes by Luna.
Mariana Seligmann goes by Muni.
Mariana Seoane goes by Mari.
Mariana Renata goes by Mar.

Mariana Ximenes goes by Mari.
The Mariana Trench runs south from central Japan, to the east of the Philippines. It's north end is a few hundred miles south of the point where the current severe earthquake activity is happening in Japan and it stretches about 1500 miles in an arc, curving east in a half-moon and southwards where the Pacific Plate dives below the Mariana Plate which holds the Mariana island arc. It's then another 1000 miles and more south to Papua-New Guinea. Because the plates are thick at this point, the Pacific plate dive a long way down to go under the Mariana Plate and the trench is the deepest place you can reach without drilling holes - it's nearly 36,000 feet deep, which is deeper than Everest is above sea level.
