Question

Usually photochemical smog is mostly produced in the summer season but it becomes denser and it effects on our health more apparent during the winter season. Can we say that the earth temperature and earth's rotation around the sun are responsible for this change? if yes please explain​

Answer 1

Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. ... The ozone layer high up in the atmosphere protects us from the sun's dangerous ultraviolet radiation. But when ozone is close to the ground, it is bad for human health.
