Answer:

3 Factors Affecting Air Pressure:

1. Temperature

2. Gravitation of Earth

3. Moisture in Air (Humidity)

Explanations and definitions :

Temperature:

As the temperature increases, air expands because of which its density decreases which results in low pressure. On the other hand air shrinks due to low temperature because of which its density increases which creates high pressure.

Gravitation of Earth:

Atmosphere glues around the Earth due to its gravitation. The intensity of gravitational pull decreases as we get away from core of Earth. Another fact is that as Earth rotates round its axis, average distance of Polar Regions and equatorial regions varies from the core of Earth. For example Polar Regions are nearer to core of the Earth as compared to Equatorial regions and hence have higher air pressure.

Moisture in Air (Humidity):

Conversion of water from liquid state to gaseous state because of evaporation is known as atmospheric humidity. Water vapours are light in weight therefore they rise up and pressure of humid air decreases as compared to dry air. Amount of water vapours changes with time and place and because of this the pressure of air also varies.
