It’s usually found in the upper atmosphere, about ten and thirty miles above. However, the gas is harmless, and it helps in forming a protective layer that protects the ultraviolet rays of the sun.

It doesn’t just happen in the summer

Many people believe that smog only gets worse in hot seasons or sunny days of the summer. It could happen at any time if the weather conditions allow it. During warmer months, the smog comes from chemicals in factory or car that reacts with the sunlight. And in the colder months, the inversion becomes common.

It causes a runny nose

Smog may also cause all kinds of problems. Even our health would be compromised because, on a typical smoggy day, anyone can experience symptoms like watery eyes, runny nose, scratchy throat, and cough. Worse, people with asthma may also experience breathing difficulty during smog days.

Affects plant growth

Crop yields would be lesser as it reduces the ability of a plane to fight off pests and diseases.
