A temperature inversion increases urban air-pollution concentration because it:
Correct answer: A. Prevents vertical mixing of polluted air
- A. Prevents vertical mixing of polluted air
- B. Raises the wind speed near the ground
- C. Converts all particulate matter into gases
- D. Increases rainfall over the emission source
Explanation
During an inversion, warmer air overlies cooler air near the surface and suppresses vertical circulation. Pollutants then remain trapped close to ground level and may reach harmful concentrations.

About Environmental Engineering
Environmental engineering examines water supply, water quality, treatment processes, wastewater collection and treatment, solid waste management, air pollution and public health protection. It covers sedimentation, coagulation, filtration, disinfection, biological treatment and disposal methods, while distinguishing drinking-water treatment from sewage treatment and BOD from COD.
