what does the ozone layer protect us from
Ozone layer acts as a shield against the ultra violet rays and protects the life on the earth. Ultra violet rays are emitted by the sun. These rays are intercepted by the ozone layer of the atmosphere before they reach the surface of the earth. Ozone layer absorbs harmful emissions from the sun and protects the life on the earth. Ozone layer is composed of ozone, a molecule made up of three oxygen atoms which are bonded together.
