The ozone layer is a deep layer in the stratosphere, encircling the Earth, that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun.
Introduction. The ozone layer is a layer of ozone particles scattered between 19 and 30 kilometres (12 to 30 miles) up in the Earth's atmosphere, in a region called the stratosphere. The concentration of ozone in the ozone layer is usually under 10 parts ozone per million.Without the ozone layer, UV radiation would not be stopped from entering the Earth's atmosphere and arriving at the surface, causing untold damage to most living species.he concentration of ozone in the ozone layer is usually under 10 parts ozone per million.
