Question

Quizplus · Accepted Answer

A temperature inversion occurs when a layer of warm air sits on top of a layer of cooler air, causing the air to be stable and preventing it from mixing. This can trap air pollutants near the surface, causing serious human health effects. Choices A and B are incorrect, as a temperature inversion actually means that air temperature increases with height above the Earth's surface. Choice C is also incorrect, as a temperature inversion tends to exacerbate the effects of air pollution.
