Air Pressure and Altitude
Imagine air as tiny bits called particles. These particles are constantly moving and bumping into things, creating pressure that surrounds us all the time.
This happens because air has weight, and gravity pulls most of it close to the Earth, causing high air pressure at the surface.
This air pressure presses equally in all directions around you.
As you go higher, like up a mountain or in a plane, there is less air above you, meaning fewer particles are pushing down. This causes air pressure to decrease.
At the top of Mount Everest, the tallest mountain, air pressure is only about one-third of what it is at sea level, making it much harder to breathe.
Changes in air pressure affect the weather, how aircraft take flight, and even how we feel.
Pilots and astronauts use special equipment to manage air pressure changes so they can breathe safely at high altitudes.
Whether you are at the beach or hiking a mountain, air pressure is always present and constantly changing.
