🌍The Earth is surrounded by a layer of air called the atmosphere, which exerts atmospheric pressure.
👂Changes in atmospheric pressure can cause our ears to pop.
🧳Changes in atmospheric pressure can crush objects, like water bottles on airplanes.
💪Our bodies can handle the atmospheric pressure because the air pressure inside us balances it.
🌬️Air rushes in and out of our ears to balance the pressure when atmospheric pressure changes.
Why do our ears pop when there is a change in atmospheric pressure?
—When there is a change in atmospheric pressure, the air inside our ears rushes out or in to balance the pressure, causing our ears to pop.
Why do objects get crushed on airplanes?
—Objects like water bottles can get crushed on airplanes due to the difference in atmospheric pressure inside and outside the bottle, caused by the change in altitude.
How is our body able to handle atmospheric pressure?
—Our body contains air in various parts, such as the ears, nose, lungs, and stomach, which exerts pressure that balances the atmospheric pressure.
What happens if the atmospheric pressure is higher than the air pressure inside our body?
—If the atmospheric pressure is higher than the air pressure inside our body, the outside air rushes into our body to balance the pressure.
What happens if the atmospheric pressure is lower than the air pressure inside our body?
—If the atmospheric pressure is lower than the air pressure inside our body, the air inside our body rushes out to balance the pressure.
00:00The Earth is surrounded by the atmosphere, which exerts atmospheric pressure on the surface.
00:58Changes in atmospheric pressure can cause our ears to pop.
02:49Objects like water bottles can get crushed on airplanes due to changes in atmospheric pressure.
04:34Our bodies can handle atmospheric pressure because the air pressure inside us balances it.
04:51Various parts of our body contain air, which cancels out the atmospheric pressure and prevents us from getting crushed.
