Question

Which of the following is correct about the pressure difference between polluted and non-polluted region?

• A. Pressure difference will be same as temperature and pollution has no relation with pressure.
• B. Pressure difference will be less
• C. Pressure difference will be high
• D. None of these

Answer 1

The correct option is C

Pressure difference will be high

Due to warming of the atmosphere, air expands. Due to the expansion of the air, the area becomes a low-pressure region and the wind from the high-pressure regions comes quickly to fill up the gap in the low-pressure region. Warm air region will be at low pressure as the amount of air will be less per unit area compared to less warm air region. The burning of fossil fuels causes pollution due to which temperature increases in the region where pollution is more. Hence pressure difference will be high if pollution is high. More the pressure difference, more will be the wind speeds and more will be destruction.
