What Is Atmospheric Pressure?


Atmospheric pressure is defined as the force per unit area that is wielded into a surface by the weight of air that is found above such as surface in a planets atmosphere. Atmospheric pressure is measures in Newtons.

bob Atmospheric pressure is caused by the weight of air molecules above it. As elevation increases, fewer air molecules are present. Therefore, atmospheric pressure always decreases

Air pressure is the force exerted on an object or area by the weight of surrounding air particles.
Atmospheric pressure is the force that the weight of the air above puts on any part of surface of the earth. Most of the time, atmospheric pressure is considered equivalent (or nearly so) to the hydrostatic pressure, which is the weight of the air above the point where the measurement is being taken.
