To control its buoyancy, the submarine has ballast tanksand auxiliary, or trim tanks, that can be alternately filled with water or air. When you fill it with water, it sinks, When you first let the water out then you let the air in (from compressed air in the submarine) it floats.

What is another word for going under something?
"Subduction" is what the earth does. Submarines "submerge".
Why submarines are able to submerge and surface?
Submarines have the capability of taking on, or getting rid of ballast, to make themselves heavier or lighter as the situation requires.
When water fills a submarines flotations tanks the overall density of the submarine?
The density will rise and submerge the submarine.
What is a ballast tank?
A ballast tank is one of several external or internal tanks fitted in submarines, which allow the boat to submerge when filled with water.
What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
Why do ships float while submarines sink?
Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.
What is the reason why submarine submerge?
Submarines submerge primarily to avoid detection and protect themselves from threats, such as enemy ships and aircraft. By diving underwater, they can utilize the ocean's layers to mask their presence and minimize the risk of being targeted. Submerging also allows submarines to conduct stealthy operations, gather intelligence, and launch missiles while remaining concealed. Additionally, submerging enables them to operate in environments where surface navigation may be compromised.
What was the nickname of the confederate submarines?
They were called (davids) after the Biblical character. The true David was a steam-powered semi sub using a very tall stack or siphon , could not totally submerge, the manually cranked Davids such as the Hunley and Pioneer could fully submerge. ( Pig Boats_ as a nickname for submarines did not come into use until World War I and the Italians restricted the term to very manueverable mini-subs also called Maiale or ( Pig Boats)
Why does the submarine float and submerge in water?
Submarines must be able to float to load and offload crew and cargo and to have repairs and maintenance. They are designed to submerge either for underwater exploration or to pass undetected by ships at the surface and planes and satellites above.
How do submarines control their density?
By their pumps and ballast-tanks: allowing water into the tanks to raise the vessel's density so can submerge, or pumping air into the tanks to displace the water and allow the submarine to surface.
What part of speech is the word submerge?
submerge is a verb. example: the submarine is about to submerge
Can submarines swim?
Submarines do not swim in the traditional sense like fish or marine mammals; instead, they navigate through the water using buoyancy and propulsion systems. They can submerge and surface by adjusting their buoyancy through the use of ballast tanks and control surfaces. While they are designed to move underwater, their operation is fundamentally different from swimming.
