describe how ozone layer is formed??

Answer 1

hope this helps you buddy.... :)

Answer 2

In the stratosphere the photochemical reaction initiated by solar UV RAYS cause the formation of Ozone and so Ozone layer.

UV rays cause splitting of Oxygen molecules into atoms. These free atoms hit normal Oxygen molecules to form triatomic Oxygen or Ozone.

In stratosphere continuous intercoversion of O2 into O3 and back happens.
