How Does it Work? - Submarines

The video follows Sarah on her first submarine adventure, exploring the science and engineering behind submarines. It explains how submarines use buoyancy to dive and rise, the role of ballast tanks, and the propulsion system that moves the submarine. The video also covers navigation using sonar, the effects of pressure at different depths, and how submarines return to the surface. It concludes by highlighting the combination of physics, engineering, and technology that enables deep-sea exploration.

Explain how submarines are built to withstand pressure as they dive deeper into the ocean.

Describe the process that occurs when a submarine is ready to resurface.
