AIR PRESSURE


Meaning of AIR PRESSURE in English

Air pressure is the weight of the atmosphere caused by the way that gravity pulls gas molecules towards the centre of the Earth. A region of high pressure is formed where air currents cause air to sink over a region of the Earth; a region of low pressure is a region where air is rising, and so reducing the normal weight of air at a place.
