The thick, heavy steel of its hull, combined with design elements such as internal steel crossbeams withstand the pressure of water pushing against them from outside. Only a few special research subs can actually go all the way to the bottom of the oceans. Most military submarines can only go down about 1000 feet before the water pressure is too great.
The pressure exerted on the hull of the sub will get too great and crush it.
A submarine cannot go to the bottom of the ocean because the pressure at such depths is too high for the submarine's structure to withstand, risking damage or collapse.
deep ocean currents.
The amount of sunlight increases
Submarine hulls are subject to sea pressure, and that pressure increases the deeper the submarine goes. There are design limits to the amount of pressure that a hull can take, and if that pressure is exceeded by diving too deep, the hull will fail and will be crushed.
tidal current
they are both at the bottom of the ocean full of seamen
tidal current
The answer to the location of the submarine is B.
The deepest submarine is built to go 10000 meters under water. This is so they can go to the bottom of the ocean floor.
sunlight increases
there is too much water pressure so it will be crushed under all the weight.
