Question

Explain how a submarine can both float and travel submerged underwater.

Answer

A submarine can float on the surface by filling its ballast tanks with air and can submerge by filling them with water. It can travel underwater using a propulsion system and can control its depth by adjusting the water level in the ballast tanks, making it more or less dense than water.
