The Navy term is "Silent Running"; when ordered, a submarine crew refers to one of the battlestations rigging bills to "Rig for Silent Running". It tells the crew which systems to shut down or reduce operations on, and all non-essential personnel not on watch or at critical tracking stations are ordered to their racks.
The usage hails from the Fleet Submarine days, when detectable noise was a real issue when dealing with attacking Destroyers of the day. Limited speed, maneuverability, and depth capability required every advantage to avoid detection, and Silent Running was part of that strategy.
Today's modern submarines are quiet enough that they are difficult to detect by anything other than another submarine, and even that's not easy with today's improved Sonar systems. However, being too quiet is also a dead giveaway in the ambient noise of the ocean; a trained Sonar crew will notice an acoustic dead spot moving through the water as well.
The ability to use the ocean environment to its advantage (depth, thermoclines) to hide in acoustic areas of advantage has also made the need for SR almost obsolete.
the name of a boat that goes underwater is called a SUBMARINE.
When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
Yes, the water pressure on a submarine increases as it goes deeper.
Yellow Submarine goes for 2 minutes and 41 seconds.
When a floating submarine submerges, it deliberately goes beneath the surface - which it is designed to do

An underwater volcano is called a submarine volcano.
Sonar was invented during World War I, with the first patent being issued in 1918. Its development was driven by the need to detect submarines and underwater objects.
As a submarine moves more quickly through the water, the fluid friction will increase. The two (the magnitude of the speed and the magnitude of fluid friction) are directly proportional. That means what happens to one happens to the other. If one goes up, the other goes up. And if one goes down, the other goes down.
Credit for the creation of the submarine goes to William Bourne, a British mathematician and former Navy gunner. He published his design for it in 1578.
quiet silent and it goes on
