Air pressure is lower at high altitudes. An airplane cabin can adjust, but as the plane rises, passengers can experience temporary pain in their ears. Check all facts below that explain why.
The air pressure in the ears increases.
The air pressure in the ears decreases.
The volume of air in the ears increases.
The volume of air in the ears decreases.
The change in volume causes discomfort.
It takes time for the ears to dispell excess air past the ear drum.

I'll go through each statement and mark whether it explains the ear pain on ascent, with a brief correction/why.
1) The air pressure in the ears increases.
- Partly true (if you mean “relative to the outside/cabin pressure”). As the plane climbs cabin pressure falls; the air trapped in the middle ear does not fall as fast, so the middle‑ear pressure becomes higher than the ambient cabin pressure.
2) The air pressure in the ears decreases.
- False (as an explanation for ascent pain). The middle‑ear pressure does not drop as quickly as the outside pressure, so it is relatively higher, not lower.
3) The volume of air in the ears increases.
- True. Because the middle‑ear pressure is higher than outside, the eardrum bulges outward slightly and the middle‑ear space volume increases a bit.
4) The volume of air in the ears decreases.
- False. On ascent the trapped air tends to expand and push the eardrum outward, so volume does not decrease.
5) The change in volume causes discomfort.
- True. The eardrum is stretched/bulged by the pressure difference and that stretching (and pressure on middle‑ear structures) is what causes the pain/fullness.
6) It takes time for the ears to dispell excess air past the ear drum.
- True with correction: air is vented through the Eustachian tube into the back of the nose/throat (not “past” the eardrum). If the tube is slow or blocked, equalization is delayed and discomfort persists.
Practical note: swallowing, yawning, chewing or performing a Valsalva maneuver helps open the Eustachian tube and equalize pressure.
