Ozone is a gas made up of molecules that are formed by three oxygen atoms. Its molecule formula is O3. Ozone is formed when the sunlight hits oxygen molecules (O2) and breaks them up into individual atoms. These individual atoms then join up with O2 molecules and make O3, or ozone.
Ozone molecules in the atmosphere provide us with important protection from the rays of the sun. Specifically, these molecules are good at absorbing certain ultraviolet rays that can cause sunburn and skin cancer.

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earthfrom its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface
