Question

Identify the wrong statements in the following:

• A. Chlorofluorocarbons are responsible for ozone layer depletion
• B. Greenhouse effect is responsible for global warming
• C. Ozone layer does not permit infrared radiation from the sun to reach the earth
• D. Acid rain is mostly because of oxides of nitrogen and sulphur

Answer 1

The correct option is C Ozone layer does not permit infrared radiation from the sun to reach the earth

Chloroflourocarbons emit nascent chlorine atoms which breaks Ozone molecule to give Oxygen molecule and responsible for Ozone layer depletion.
When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.The absorbed energy warms the atmosphere and the surface of the Earth. This phenomenon is known as Greenhouse Effect.
Ozone does not hinder infrared radiation. Ozone layer absorbs UV- rays not Infrared radiation.
Oxides of nitrogen and sulphur react with water to give acid which on mixing with rain comes to earth. So, these are responsible for acid rain.
