Have you heard that the ultraviolet radiations from the sun may cause skin cancer? Can you tell me which layer of the earth’s atmosphere protects the earth from these dangerous ultraviolet radiations of the sun?
A. Stratosphere B. Ozonosphere C. Ionosphere D. Troposphere
Ozonosphere-the ozonosphere is a layer of the atmosphere, which contains a blanket of the ozone gas, this, is also called the ozone layer. the presence of the ozone layer in the upper atmosphere, blocks almost all ultraviolet solar radiations from reaching the earths surface. these radiations can injure or kill most living things. however, large-scale use of ozone destroying gases like chlorofluorocarbons (cfcs) is leading to the depletion of the ozone layer. in fact a very large hole in the ozone layer has been detected over the antarctica, near the south pole.
