Question
Statement I: The global atmosphere is currently warming.
Statement II: The depletion of the stratospheric ozone layer has increased the amount of ultraviolet radiation reaching the earth.
- Statement I is correct, statement II is incorrect.
- Statement I and II are correct.
- Statement I is incorrect, statement II is correct.
- Statement I and II are incorrect.
Hint:
Global warming is increasing the temperature of the Earth and greenhouse gases are reacting with ozone in the stratosphere and depleting it
The correct answer is: Statement I and II are correct.
Due to greenhouse gases and greenhouse effect the atmosphere is heating up. The free chlorine and other elements formed due to breakdown of CFC's etc. in the atmosphere and then these react with the stratospheric ozone thereby depleting it and causing more UV light to come through
