प्रश्न
How does the following element influence the weather of a place?
Pressure
उत्तर
Pressure: Atmospheric pressure is the pressure that the atmosphere exerts on the surface of the earth because of its weight. There is a close relationship between pressure and temperature — high temperature means low pressure and vice versa. The pressure difference causes horizontal movement of air called wind and vertical movement of air called current, which together cause circulation of air in the atmosphere.
