100 Words Essay on Submarine
What is a Submarine?
A submarine is a special kind of ship that can go underwater. Unlike regular ships that float on top of the water, submarines can sink on purpose and move beneath the surface. This allows them to explore the ocean or travel without being seen.
How Submarines Move
Submarines use engines to move forward. To go deeper into the water, they fill large tanks with water to become heavier. When they want to come back up, they push the water out of these tanks to become lighter.
Uses of Submarines
Submarines are used for many things. They can be used by the navy to protect a country, by scientists to study the ocean, and sometimes even to take people on deep-sea adventures to see underwater life.

What is a Submarine?
A submarine is a special kind of ship that can go underwater. Unlike regular ships that float on top of the water, submarines can sink on purpose and move beneath the surface. This allows them to explore the ocean in ways that other ships cannot.
How Submarines Move
Submarines use engines to move forward. To go underwater, they fill large tanks with water, which makes them heavy enough to sink. When they want to come back up, they push the water out of the tanks with air, which makes them lighter and allows them to float to the surface again.
The Uses of Submarines
Submarines are used for many different things. The navy uses them to protect the country by hiding underwater where enemies can’t see them. Scientists use submarines to study the ocean and the creatures that live there. Some companies even have small submarines to take people on tours of the underwater world.
Conclusion
Submarines are fascinating ships that can go underwater. They move by controlling their weight and use engines to go forward. They serve many purposes, from defense to research and exploration. Submarines open up a whole new world beneath the sea for us to learn about and enjoy.
500 Words Essay on Submarine
What is a Submarine?
A submarine is a special kind of ship that can go underwater. Unlike regular ships that float on top of the water, submarines can go beneath the surface. This allows them to explore the deep parts of the ocean where humans can’t easily reach. Submarines are very important for several reasons. They help scientists learn more about the ocean, they are used by the navy to protect a country, and they can also be used for rescue missions.
How Do Submarines Work?
You might wonder how submarines can stay under the water without sinking. Well, submarines have special tanks called ballast tanks that can be filled with water or air. When the tanks are filled with water, the submarine becomes heavy and goes down into the water. When the tanks are filled with air, the submarine becomes lighter and rises to the surface. This system allows the submarine to control its depth and position in the water.
The History of Submarines
Submarines have been around for a long time. The first submarines were simple and not very effective. Over time, they have become more advanced. The first successful submarine was built in the 17th century, but it was very different from the submarines we see today. Modern submarines are powered by nuclear energy or diesel engines, making them faster and able to stay underwater for a longer time.
Life Inside a Submarine
Living in a submarine is not like living on land. Space is limited, and there is no natural light. People who work on submarines have to stay underwater for many weeks or even months. They breathe air that is made fresh again and again inside the submarine. They eat, sleep, and work in the same small space. It requires teamwork and discipline to live and work in such close quarters.
Uses of Submarines
Submarines are used for many different things. Navies use them to protect their country’s waters. They can sneak up on enemy ships without being seen. Scientists use submarines to study the ocean. They can take pictures and collect samples from deep underwater. Sometimes, submarines are used to find shipwrecks or to help in rescue missions when ships sink.
The Future of Submarines
The future of submarines looks exciting. New technologies are making submarines even more powerful and easier to use. For example, some new submarines can stay underwater for longer periods without needing to surface for air or supplies. There are also plans to use submarines for tourism, allowing people to explore the deep ocean and see amazing sea life.
In conclusion, submarines are fascinating machines that allow us to explore and use the ocean in ways that were once impossible. They have a rich history, serve many purposes, and promise an exciting future as technology continues to advance.
