How do submarines float or sink?

$\huge\red{\underline{{\boxed{\textbf{ANSWER}}}}}$

A submarine has large tanks called ballast tanks onboard that control how deep the submarine sinks or how high it rises. To sink, the tanks fill with water. A large the amount of water in the ballast tank causes the submarine to sink. Less water in the tanks cause it to sink less. To raise the submarine, the water is released from the ballast tanks and compressed air (that is kept onboard in flasks) is let into the ballast tanks. The more compressed air that is added the more the submarine rises. If a lower the amount of compressed air is pumped into the tank, the sub will not rise as much.
