Ozone is also destroyed naturally in the stratosphere, being dissociated by ultraviolet radiation: This is the reaction that is responsible for O3's absorbtion of uv radiation that would otherwise reach earth.
As a result, the largest ozone produc-tion occurs in the tropical stratosphere.The production of stratospheric ozone is balanced by its destruction in chemical reactions. Ozone reacts continu-ally with sunlight and a wide variety of natural and human-produced chemicals in the stratosphere.
