How is air pressure made
WebWhat causes air pressure in simple terms? The force exerted by an air mass is created by the molecules that make it up and their size, motion, and number present in the air. These factors are important because they determine the temperature and density of the air and, thus, its pressure. WebVerified by Toppr. The weight of the air above us creates air pressure. Explanation: Air has weight. The Earth's gravity exerts a force on air molecules, just as it does on us. The …
