Question

Air ____ as a diver comes up from depth due to pressure

A) compresses
B) expands
C) pressurizes
D) depresses

Answer 1

D) depresses

Step-by-step explanation:

When you dive, the water builds pressure and the the antonym (opposite) of pressurize is depressurize. Therefore, the water pressure depresses.

Answer 2

B) Expands

Step-by-step explanation:

When the diver surfaces- one of the most important rules is to be continuously breathing. Never hold your breath when ascending. This is due to the air in the lungs will start to expand because there is less pressure of the water exerted on the body. Holding your breath can cause catastrophic injury to divers lungs.
