The sensation of popping in the ears during airplane travel is typically caused by changes in air pressure. As the airplane ascends or descends, the pressure inside the ear is different from the pressure outside, leading to the popping sensation. Swallowing, yawning, or chewing gum can help equalize the pressure and relieve the discomfort.
The change in air pressure as the airplane ascends or descends can cause your ears to pop. Your Eustachian tube, which helps regulate air pressure in your middle ear, may have trouble equalizing the pressure, leading to the popping sensation. Swallowing, chewing gum, or yawning can help relieve the pressure and stop the popping.
As the airplane ascends to 30,000 feet, the air pressure outside the airplane decreases. This is because air pressure decreases with altitude due to less air molecules exerting pressure on the aircraft. The difference in pressure between the inside and outside of the airplane is managed by the aircraft's pressurization system to ensure a comfortable environment for passengers and crew.
Atmospheric pressure decreases as one ascends from the beach to the mountains.

A bag of crisps expands on planes due to changes in air pressure as the aircraft ascends. At higher altitudes, the atmospheric pressure decreases, causing the air inside the sealed bag to expand. Since the bag is airtight, this expansion results in the bag puffing up. Once the plane descends and pressure increases, the bag may return to its original shape.
When the plane ascends or descends, the air pressure inside the cabin changes, causing your ears to feel blocked. This is due to the Eustachian tube, which helps equalize pressure in your ears. Swallowing, chewing gum, or yawning can help alleviate this discomfort by opening the Eustachian tube and allowing air to pass through.
Divers breathing compressed gases at depth are themselves under pressure. For each 33 feet/10 meters that a diver descends, they add approximately 1 atmosphere of pressure to their body. When they breathe gases whilst their bodies are under this pressure, the gases dissolve into their bodies tissues. When they ascend, the pressure is relieved, and gases are released. Provided that diver ascends sufficiently slowly, the gases are released slowly and no problems result. But if the diver ascends too slowly without allowing the gases to expire at a slow enough rate, then the diver will suffer decompression sickness when gas bubbles form in the diver's tissues and blood.
Median is the middle number of a list that ascends or descends in order. 30 would be the median of 28, 30, 30, 31, 31.
Crude pain is transmitted via A-delta and C fibers to the spinal cord and then ascends to the brainstem and thalamus. From the thalamus, the pain signals are projected to the somatosensory cortex for processing and perception.
If a hot air balloon ascends too high, the air pressure decreases and the balloon may burst or lose control, potentially causing it to crash.
