What is Atmospheric pressure and The Factors Influence a.p

Atmospheric pressure:

The weight of the column of air at any given point on the earth surface is called Atmospheric Pressure, and It is also Known as Barometric Pressure because Barometer records the atmospheric pressure

The Factors Influence 


With an increase in the altitude, the length of the column of the overlying air on the surface of the earth decreases and hence the weight or the pressure exerted by the atmosphere also decreases.


When the atmospheric temperature increases, the air expands and loses density and similarly when the temperature decreases the air becomes denser and naturally a.p increases.

3.Water Vapour:

Water Vapour is lighter than the dry air so,if the content of water vapor in the air is higher, The a.p would be lower and vice-versa.

4.Atmospheric Pressure and air currents:

When temperature increases in an area, the air becomes lighter nd rises up, as a result, a low pressure develops there and to fill up the void and neutralize that low pressure, Cooler air descends in that area.

Ours is a youth-led virtual learning platform with dedicated social scientists and students. We aim at providing virtual guidance to the ones taking their first steps into the world of Social Science, either through formal education or because of their never-ending quest for learning. We believe in sharing with our readers the knowledge that we have gained, through simple transcription of social theories and their real-life application. We also believe in the power of knowledge in making the world a better place to thrive and survive.
