Question

what is ozone layer

Answer 1

Ozone is an atmospheric layer at heights of about 20 to 30 miles (32 to 48 kilometers) that is normally characterized by high ozone content which blocks most solar ultraviolet radiation from entry into the lower atmosphere.

The main advantage of the ozone layer is that it absorbs the ultra violated rays(UV rays)of the sun ,preventing it to reach the earth's surface,which is very harmful.If the ozone layer was not present ,then the life on earth would be really difficult.The ozone layer is getting affected due to human activities and pollution.We have to try our best to save it.....

Hope this helps u.............^_^
