Answer 2

The correct solution to the given question is option C: Air pressure outside our ears decreases.

• As we climb higher in altitude, the layer of the atmosphere thins, lowering atmospheric pressure.
• Because of the large air pressure differential caused at higher altitudes, our ears pop.
• The eustachian tube present in our ear is responsible for maintaining air pressure homeostasis.
• Due to a significant drop in air pressure, this tube abruptly opens, causing a pop sound to equalize pressure inside and outside.
• As a result, as the outside air pressure drops, ears pop.
