Question

How do chlorofluorocarbons affect Earth's ozone layer?
Answer: When UV radiation hits a CFC molecule it causes one chlorine atom to break away. The chlorine atom then hits an ozone molecule consisting of three oxygen atoms and takes one of the oxygen molecules, destroying the ozone molecule and turning it into oxygen.

Answer 1

Chlorofluorocarbons will influence earth's ozone layer when UV radiation hits a CFC particle it makes one chlorine iota split away.

The chlorine particle at that point hits an ozone particle comprising of three oxygen iotas and takes one of the oxygen atoms, obliterating the ozone atom and transforming it into oxygen.
