EXCLUSIVE: Graham Greene, most recently on the A&E (and now Netflix) crime drama Longmire, has joined Sam Worthington and Octavia Spencer in Lionsgate âs faith-based feature film The Shack.
The hole in the ozone layer happens because the ozone in the stratosphere is destroyed by chlorine and bromine from halogen atoms. These atoms come from man-made halocarbon refrigerator gases (chlorofluorocarbons [CFCs], freons and halons) which are emitted at ground level but move up into the ozone layer.zone depletion was observed to increase as emissions of halo-carbons increased. Ozone is a protective layer in the upper atmosphere. It is formed when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.
Ozone is a gas that is present in the ozone layer in the stratosphere of the Earth. 1  There, it will absorb almost all ultraviolet light which is harmful to many organisms. The term Ozone depletion can refer to a number of distinct, but related phenomena: Since about the 1970s, there has been a decrease in total volume of the Ozone in the ozone layer, of about 4%, per decade. There are seasonal variations in the ozone layers; in springtime, there is less ozone in the ozone layer over the polar regions, esp. the south pole. This is generally known as ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events. The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens.
