Air Exerts Pressure

Air Exerts Pressure: The pressure exerted by air is called air pressure. The air in the atmosphere exerts pressure on every object and in all directions (up, down, left, right, etc.). The pressure exerted by the atmosphere depends on many factors. For example, it depends on the height of a place and also on the temperature. Generally, places at a lower temperature are at a higher pressure than places at a higher temperature. Air moves from an area of higher pressure to an area of lower pressure.
