Question

What is the difference between the type of smog experiences by cities in the Eastern United States and that found in Southern California?

Answer 1

Whenever smog forms in dry air, it often takes on the characteristics of Los Angeles-style smog. Photochemical interactions between hydrocarbons and sunlight lead to the formation of this substance.

Smog that resembles Eastern United States is really a mixture of smoke and fog, which is common in moist areas.
