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.
A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
Give an example of what you mean. For example a piece of sand sinks to the bottom of the ocean in the same way that a submarine sinks to the bottom of the ocean so please be more specific in terms of what you are asking. Bigger means larger in volume Lighter means smaller in mass

your answer is subduction
The ocean and soil
The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.
If a submarine takes on enough water, like any vessel, it'll sink straight to the bottom without intervention.
subduction is the answer.
the ocean sinks and the land expands
A submarine is a ship that sinks itself in a controlled manner by flooding tanks with water and returns to the surface in a controlled manner by blowing the water out of those tanks with compressed air. The main uses of submarines so far have been military, where a ship that cannot be seen is needed.
changing in heat in the ocean colder sinks warmer floats
subduction
