Ozone layer prevents the harmful……………… radiation of the sun to reach the earth.

A considerable part of the harmful ultraviolet radiation of the sun does not reach the surface of earth. This is because in the upper atmosphere, there is a layer of

A considerable part of the harmful ultraviolet radiation of the sun does not reach the surface of earth. This is because in the upper atmosphere, there is a layer of

Which of the following, present in the stratosphere prevents 99.5 percent of the sun’s harmful UV radiations from reaching the earth’s surface ?

Assertion : Ozone is destroyed by CFCs in the upper stratosphere. Reason : Ozone holes increase the amount of UV radiation reaching the earth.

Ozone layer protect us from the harmful effects of..........radiations.

Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun. The use of chloroflurocarbon (CFC) in aeroslos and refrigrators, and their subsequent escape into the atomsphere, is blamond for making holes in the ozone layer over the Antarctic, and Arctic. Ozone acts as a strong oxdising agent in acidic and alkaline medium. For this property ozone is used as a germicide and disinfectant for sterillising water and improving the atmosphere of croweded places. CFC damages ozone layer by reactions :

Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus protecting the people on the earth from the harmful UV radiation from the sun. The use of chlorofluorocarbon (CFC) in aerosols and refrigerators, and their subsequent escape into the atmosphere, is blamed for making holes in the ozone layer over the Antarctic, and Arctic. Ozone acts as a strong oxidizing agent in acidic and alkaline medium. For this property ozone is used as a germicide and disinfectant for sterilizing water and improving the atmosphere of crowded places. which of the following statements is correct ?

Fill in the blanks : Ozone depletion is mainly caused by the active………… atoms generated from CFC in the presence of UV radiation.

Fill in the blanks : Decrese of the concentreation of ozone in the stratosphere is the cause of formation of………. holes.
