Atmospheric pressure, also known as air pressure, refers to the weight of the atmosphere pressing down on the Earth's surface. It is the force exerted by the weight of air molecules in the atmosphere and is typically measured in units such as pascals (Pa) or millibars (mb). Atmospheric pressure decreases with altitude, meaning that as one ascends in elevation, there are fewer air molecules above, resulting in lower pressure. This phenomenon significantly influences weather patterns and climate, as variations in atmospheric pressure can lead to the formation of wind, storms, and other meteorological events.

Air pressure is a specific term often used interchangeably with atmospheric pressure, but it can also refer more broadly to the pressure exerted by air in a given space, regardless of altitude. It is a crucial factor in various physical processes, including the behavior of gases and the functioning of meteorological instruments. Air pressure is influenced by temperature, humidity, and altitude, and can be measured using barometers. Changes in air pressure are essential for understanding weather systems, as they contribute to the movement of air masses and the development of different climatic conditions.
