Why should deep-sea divers come up slowly while returning to the surface?
Answer and explanation
Correct answer: Dissolved gases may form bubbles rapidly when pressure decreases
At deep-sea pressure, more inert gas, especially nitrogen, can dissolve in a diver's blood and tissues. A rapid ascent causes the surrounding pressure to fall before the body can remove that gas safely through breathing. The dissolved gas may then form bubbles, producing decompression sickness and related injury. A controlled ascent allows gradual release; the other choices are unrelated physical claims.
