Scientific Article: The Ozone Layer The Ozone layer is located in the Earth’s upper atmosphere. It acts as a barrier and absorbs majority of UV radiation before it hits Earth’s surface. Ozone is made up of three oxygen atoms that are naturally occurring molecules. The depletion of the ozone has become a worldwide issue and is caused by the release of CFCs into the atmosphere. CFCs release chlorine atoms which break down ozone molecules. The depletion of the ozone layer threatens to leave life on

continent-size hole in Earth ’s ozone layer keeps getting bigger and bigger. Each year since the late 1970s‚ much of the protective layer of stratospheric ozone above Antarctica has disappeared during September‚ creating what is popularly known as the ozone hole. The Antarctic hole now measures about 9 million square miles‚ nearly the size of North America. Less dramatic‚ still significant‚ depletion of ozone levels has been recorded around the globe. With less ozone in the atmosphere‚ more ultraviolet
