पर्याय

Answer 1

Smog is common in winter mornings in big cities.

Explanation:

Smog is a mix of smoke and fog and is especially common on cold, calm winter mornings when vehicle and industrial emissions are trapped near the ground; this occurs most often in cities because they produce much more smoke/soot than villages or hill stations.
