Question

Describe how zone layer is formed?​

Answer 1

Answer:

ozone is a form of oxygen .It is present in rare amount in the earth's atmosphere . Approximately one molecule out of every two million present in the atmosphere is ozone .In the troposphere,ozone is generated only in small amount .But in the stratosphere at 20-50km above sea level it is present in significant amount

Answer 2

Answer:

Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. In the first step, solar ultraviolet radiation breaks apart one oxygen molecule (O2) to produce two oxygen atoms (2 O) (see Figure Q2-1).
