What is atmospheric pressure also known as?

Atmospheric pressure is commonly referred to as air pressure, which is the force exerted by the weight of the air above a particular point in the Earth's atmosphere. It is a fundamental concept in meteorology and physics, as it influences weather patterns and various atmospheric phenomena.

The term "air pressure" emphasizes the fact that it is specifically the pressure that air exerts in its environment. This pressure can vary with altitude—the higher you go in the atmosphere, the lower the pressure, because there is less air above you pushing down.

In contrast, external pressure, breathable pressure, and static pressure do not accurately capture the specific nature of atmospheric pressure. External pressure might refer to pressure exerted by an environment or other forces outside of a given system, while breathable pressure is not a standard term used in meteorology. Static pressure typically refers to a specific type of pressure that does not account for motion and is often used in different contexts, such as fluid dynamics. Thus, air pressure is the most appropriate and commonly accepted term for atmospheric pressure.
