Question

What is smog? How is smog formed? What are its harmful effects?

Answer 1

Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air.

Smog is a deadly air pollutant that is formed by the combination of smoke and fog( The

minute water particles suspended in the air near the surface of the earth during cold weather in winter is called fog.)

Smoke contains tiny carbon particles and harmful gases such as nitrogen oxides and

sulphur dioxide. The carbon particles, nitrogen oxides and sulphur dioxide of smoke combine with the condensed water vapour called fog to form smog.

Smog causes cough and aggravates asthma and other lung diseases,

especially in children.
