Normal ships are designed to move on the surface of the water. Submarines are designed to be able to submerge and travel under the water's surface, as well as on the surface.
When normal ships go down, they stay down. Submarines are able to come back up after they go down.
All American submarines are nuclear powered. With the exception of Aircraft carriers, surface ships are powered conventially.
a ship floats on the water and a submarine can go underwater and on top of the water
A submarine is a ship that can travel underwater.
submarine.
A submarine best fits the description.
Submarine - A ship designed to travel underwater used for exploration and warfare. Submarine - A sandwich that is shaped like the submarine ship, also known as a grinder or hoagie.
"Navy" is a military institution operating on the water, whereas "seaman" refers to a specific grade of military personnel serving aboard a ship or submarine in the Navy. It is kind of like the difference between government and a senator.

"The submarine fired a torpedo at the large ship."
A submarine is to spy on ship movements and if necessary sink ships
Nothing. A schooner IS a tall ship.
Using Archimedes' Principle, it is clear that a change in mass of an object affects how much liquid has to be displaced. In submarines, this is controlled by ballast tanks which are found between the submarine's inner and outer hulls.. When the tanks are empty, the submarine has less mass and it floats like a normal ship. As water is allowed into the tanks, the mass of the submarine increases, the downward gravitational force on the submarine increases and the submarine begins to sink. Careful balancing of the water ballast enables the craft to stay at any chosen depth.
