Air pressure is caused by the weight of air molecules pressing down on a surface due to gravity. As air molecules are pulled toward the Earth's surface, they exert force on objects, creating pressure. Factors such as temperature, altitude, and humidity can also influence air pressure, with warmer air being less dense and exerting lower pressure, while colder air is denser and exerts higher pressure. Changes in air pressure can lead to weather phenomena and affect wind patterns.
