They use a periscope. See the related link for more information.

What the name of the instrument used by submarine to allow the crew to see above the surface of water?
Periscope.
How do you see out of a submarine?
Other than the periscope, which was designed to be extended up above the surface of the water to see what's on top, there isn't really a way to look out of a naval submarine. There are no windows or the like.
How does a crew see the surface of water in a submarine?
Traditionally, by using a periscope to view optically above the surface. As periscopes are a weak point in a submarine - modern nuclear submarines use external cameras instead of periscopes.
What is the name of a submarine viewing device?
Submarines can see the surface of the ocean with a periscope when they are close to the surface.
Which instrument is used to observe objects on the surface from a submarine?
A periscope is used to observe the surface from a submarine
Where periscope can be used?
In a submarine where it stays underwater but can see on surface. Or in a war it is used in trenches to see over the top without getting shot.
What are the uses of a periscope in a submarine?
The periscope is used by the submarine to look around the surface of the water, while the rest of the submarine is under water. It makes the submarine harder to find and destroy by enemy antisubmarine warfare. The periscope might be just a simple set of mirrors or it might have a "heads up display", similar to HUD found in some combat aircraft, that give the range to the target, as well as a magnifying glass that also makes the target easier to see, similar to a pair of binoculars.
What will float then sink then float?
[I've heard this question asked as a kind of a twisted riddle, the answer to which is, "A drowning person": When a person is first in the water, they have air in their lungs and will float. As they drown, their lungs fill with water and they sink. Then, as their body decays and gases expand, the body floats to the surface -- LibertarianLaw]A submarine or a ship can float because the weight ofwater that it displaces is equal to the weight of the ship. This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below). When the submarine is on the surface, the ballast tanks are filled with air and the submarine's overall density is less than that of the surrounding water. As the submarine dives, the ballast tanks are flooded with water and the air in the ballast tanks is vented from the submarine until its overall density is greater than the surrounding water and the submarine begins to sink (negative buoyancy). A supply of compressed air is maintained aboard the submarine in air flasks for life support and for use with the ballast tanks. In addition, the submarine has movable sets of short "wings" called hydroplanes on the stern (back) that help to control the angle of the dive. The hydroplanes are angled so that water moves over the stern, which forces the stern upward; therefore, the submarine is angled downward.
Do people go in submarines for fun?
Yes definitely. Maybe not military class submarines but there are many public submarine tours that take you under the water to see shipwrecks, sea life etc
Where is capt sterns submarine in emerald?
Team Aqua/Magma took it underwater. Dive a look around for a secret entrance underwater and go in it. You will see the submarine. Then one you are at the sub, go up to the surface above it and defeat team Aqua/Magma.
Compare the advantages and disadvantages of using surface water and ground water as a source of freshwater?
Advantages: 1.) Surface water can be easily retrieved and carried in buckets 2.) Surface water stops isomorphic deterioration of the surface land below it. 3.) Surface water evaporates thus making clouds Disadvantages: 1.) Surface water kills loads of people every month. If there were no surface water, people in major cities wouldn't have to worry about drowning every day. 2.) Surface water killed a whole load of bison. And that's terrible. 3.) Surface water provides a very easily accessible hideout for terrorists and criminals running from law enforcement officials. Breaks bullets, too, so they can't shoot at them even if they see them hiding.
Where does surface water travel?
Surface water flows downhill or seeps into the ground becoming groundwater. The natural flow of surface water is downhill or seaward. See the related link for more information.
