Question

Quizplus · Accepted Answer

When a swimmer attempts to snorkel more than a meter deep, the pressure on the lungs increases due to the weight of the water above. Air at the surface will not freely enter the compressed lungs because of the higher pressure region. This can cause discomfort, shortness of breath, and possible lung injury. Therefore, option D is the correct choice. The other options (A, B, C, and E) are not accurate explanations of why a snorkeler can't go deeper than a meter.
