What is the pressure of the weight of the air and water vapor on the surface of the Earth known as?

The pressure caused by the weight of the air and water vapor on the surface of the Earth is known as atmospheric pressure. This pressure is the result of the gravitational force acting on the air molecules in the atmosphere and is typically measured in units such as pascals, inches of mercury, or millibars. Atmospheric pressure varies with altitude, weather conditions, and temperature, but it is most commonly recognized as the standard pressure at sea level, which is approximately 101.3 kPa (kilopascals) or 760 mmHg (millimeters of mercury).

Understanding atmospheric pressure is crucial for various applications, including meteorology, aviation, and any field that concerns gas laws, since it affects the behavior of gases under different conditions. Other types of pressure mentioned, like static pressure, dynamic pressure, and hydrostatic pressure, relate to different contexts and phenomena. Static pressure refers to the pressure exerted by a fluid at rest, dynamic pressure pertains to the pressure associated with fluid motion, and hydrostatic pressure applies to the pressure in a fluid at rest due to the weight of the fluid above.
