What is atmospheric pressure?

Answer 1

Atmospheric pressure:

1. The atmospheric pressure at a point is defined as the force acting normally on a unit area around that point, due to the total height of the air column of the atmosphere above it.
2. That pressure is known as atmospheric pressure, also known as air pressure.
3. It is the force exerted by the air above a surface as gravity pulls it to Earth.
4. A barometer is commonly used to measure atmospheric pressure.
