Definition
Air pressure is the force exerted by the weight of air above a given point. 💨 It's caused by the constant motion of air molecules colliding with surfaces. Imagine the air molecules like tiny bouncy balls hitting you from all directions; the combined force is air pressure. Air pressure varies depending on altitude and temperature. Higher altitudes have lower air pressure because there's less air above. Changes in air pressure can indicate weather patterns; falling pressure often signals an approaching storm. Air pressure is essential for many processes, from breathing to flying airplanes. It's the invisible force that shapes our atmosphere.
