Sagot :
Air pressure is caused by the mass of the air being pulled down by the gravity of the earth over a particular object or surface.
What do you mean by gravitation?
Any two mass-containing objects are drawn together by the gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive. In reality, everything in the cosmos is tugging on everything else, including you!
The force that air applies to the earth's surface is known as air pressure (also known as atmospheric pressure).
Gravity and its impact on the gaseous molecules that make up the atmosphere are primarily responsible for its existence.
As a result, the atmospheric pressure varies with height and air temperature.
A relief's altitude, or how high it is above sea level, determines its relative height and, thus, its air pressure.
This explains why vast mountain ranges have a thinner atmosphere because gravity holds most of the air close to the surface.
