What do smog look like?

Smog typically appears as a thick, hazy layer of air pollution, often giving the sky a gray or brownish tint. It can obscure visibility, making distant objects appear blurred or indistinct. Smog is most commonly seen in urban areas with high levels of industrial activity and vehicle emissions, especially during warm, stagnant weather conditions. The presence of smog can also lead to a noticeable odor and a feeling of heaviness in the air.
