AThe temperature stays constant from top to bottom
BThe water density falls and the diver floats
CThe water pressure rises sharply, crushing the body
DThe light intensity blinds the eyes of the diver
Answer & Solution
Correct answer: C. The water pressure rises sharply, crushing the body
1. P = h * rho * g says pressure rises with depth.
2. At great depth the water pressure can be many times atmospheric.
3. The suit balances this external pressure to keep the body safe.
4. So option A is correct.
