how does ozone layer gives us protection? what will be effect ?

The Ozone Layer is a planetary sunscreen and it plays a vital part in protecting us from most of the sun's harmful radiation.The ozone layer prevents much of the ultraviolet (UV) light from the sun from reaching the Earth. Ultraviolet light strikes oxygen molecules in the stratosphere - the layer of the atmosphere located directly above the one we breathe, which includes a thin ozone layer - and splits them into two oxygen atoms. Each of these atoms, when it encounters another oxygen molecule, combines with the molecule to make ozone. The UV light also breaks the ozone into an oxygen molecule and an oxygen atom. This is called the ozone-oxygen cycle, and it protects the Earth from UV radiation by converting the radiation to heat.

It is also well explained in the study material at the link http://cbse.meritnation.com/study-online/study-material/4wi67BZOE9c3dqh2@Znadw!!/GTcFmwRNIqN6xcZFQ9ZZ3Q!!
