Topic: Atmospheric Pressure. Why don't we get crushed by atmospheric pressure? Hey. Did you hear that? His ears popped. Is this related to atmospheric pressure? Yes. We know that our earth is surrounded by a layer of air called the atmosphere. The gravitational force of earth constantly pulls this atmosphere towards itself. Due to this, the atmosph... Read More

Key Insights

• ❓ Earth's atmosphere exerts pressure on objects, known as atmospheric pressure.
• 😍 Changes in atmospheric pressure can lead to ear popping and bottle crushing during flights.
• 😍 The internal air in our body balances the atmospheric pressure, preventing us from being crushed.
• 🙃 Atmospheric pressure at sea level exerts about 14.7 psi of force on our body.
• 😍 Understanding atmospheric pressure helps explain phenomena like ear popping and bottle crushing.
• 👱 External air pressure and internal air pressure in the body cancel out, preventing us from feeling crushed.
• ❓ Atmospheric pressure is crucial for various natural processes and phenomena on Earth.

Questions & Answers

Q: Why do our ears pop during changes in atmospheric pressure?

Our ears pop because the air pressure inside rushes out or in to balance with the changing atmospheric pressure, affecting our eardrums.

Q: Why do water bottles sometimes get crushed during flights?

Water bottles get crushed due to differences in atmospheric pressure inside the bottle and outside, caused by low pressure in airplanes.

Q: How is atmospheric pressure related to lifting heavy objects?

We are also under immense atmospheric pressure, but internal air in our body balances it, preventing us from being crushed like lifting a car.

Q: How does our body handle the pressure from the atmosphere?

Various body parts like ears, nose, lungs, and stomach contain air that exerts pressure, balancing atmospheric pressure, preventing us from being crushed.

Summary & Key Takeaways

• Earth's atmosphere exerts pressure on objects, called atmospheric pressure.

• Changes in atmospheric pressure cause ear popping and bottle crushing.

• The body's internal air pressure balances atmospheric pressure to prevent being crushed.
