Interpretation Introduction

Interpretation:

The reason for the formation of good and bad ozone molecules is to be explained.

Concept Introduction:

In the stratosphere, small concentrations of ozone occurs naturally which is related to the upper atmosphere of earth. It protects life from the ultraviolet radiation which can cause skin cancer, cataracts, damage crops, and disrupt marine life.
