Explanation:

That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.

One of the most noticeable effects of shifting air pressure occurs when a plane changes altitude rapidly. As expanding or contracting air in the middle ear equalizes its pressure with the surrounding atmosphere, ear popping and pain are common.

Meteorologists use a unit for pressure called a millibar - and the average pressure at sea level is 1013.25 millibars. A blown-up balloon is a good example of atmospheric pressure. ... An airliner is virtually a pressure capsule—like a big aluminum can filled with air.
