Does your ears pop when you’re flying on an airplane? one third of all passengers will experience this ear pain at least once.
So, Why do your ears pop in airplanes?
Rapid changes in air pressure inside the aircraft cause the air pocket inside the ear to expand during takeoff and contract during descent, stretching the eardrum. To equalize pressure, air must enter or escape through the Eustachian tube.
Airplanes cabin pressurization is the active pumping of air into an aircraft cabin to increase the air pressure within the cabin. Planes are pressurized as cruising altitudes are freezing and lack sufficient oxygen to breathe inside.
Other than it’s reputation as predators, Sharks can also save lives by giving early warnings of storms.
British research has found that they can sense minute changes in air pressure and head for the safety of deeper waters when a storm is brewing. A drop in air pressure – a sign of imminent bad weather – is mirrored in the pressure of the water.
