Question
How does the following element influence the weather of a place?
Pressure
Solution
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.

This could be a classroom activity. If your school laboratory has an anemometer, use it to record your city’s wind speed for a week. Use the Beaufort Scale to find out the character of wind during these days. Record your observations carefully in your notebook. You could even draw small neat sketches to show the effect of the wind.
