How do temperature inversions affect air quality?

• A. They increase the dispersion of pollutants
• B. They trap pollutants close to the ground
• C. They completely eliminate air pollutants
• D. They enhance the effects of rainfall

Answer: (B)

Temperature inversions significantly impact air quality by trapping pollutants close to the ground. Under normal atmospheric conditions, air temperature decreases with altitude. However, during a temperature inversion, a layer of warmer air sits above cooler air near the surface. This creates a stable atmosphere that prevents vertical mixing. As a result, airborne pollutants, such as smoke, dust, and other particulates, become confined within the layer of cooler air. Instead of dispersing into the atmosphere, these pollutants accumulate, leading to poor air quality and potentially dangerous health effects for those exposed. This phenomenon is particularly pronounced in urban areas with high levels of emissions, where inversions can lead to smog and increased respiratory issues among the population. In contrast, the other choices do not adequately describe the dynamics involved: temperature inversions do not enhance pollutant dispersion or eliminate pollutants, and while they can influence rainfall patterns, this is not their primary effect on air quality.
