Assertion : Ozone is destroyed by \(CFCs\) in the upper stratosphere. Reason : Ozone holes increase the amount of \(UV\) radiation reaching the earth
1 Assertion and reason are incorrect
2 Assertion is false, but the reason is correct
3 Assertion and reasons are both correct, and the reason is the correct explanation for the assertion
4 Assertion and reason are correct, but the reason is not the explanation for the assertion
Explanation:
The upper stratosphere consists of ozone \((O_3)\), which protect us from harmful ultraviolet \((UV)\) radiations coming from sun. The layer get depleted by \(CFC’s\)

Excessive release of \(CO_2\) into the atmosphere results in
1 formation of smog
2 depletion of ozone
3 global warming
4 polar vortex
Explanation:
Carbon dioxide is very important for maintaining the climate which is suitable for our survival. \(CO _2\) has the property of trapping heat from the sun. So higher the level of carbon dioxide, the higher will be the heat trapped. This leads to the rise in the temperature of the earth, resulting in global warming. Therefore, we can say excessive release of \(CO _2\) into the atmosphere results in global warming.

The layer of atmosphere between \(10\, km\) to \(50\, km\) above the sea level is called as
1 troposphere
2 mesosphere
3 stratosphere
4 thermosphere
Explanation:
The layer of atmosphere between \(10 \,km\) to \(50 \,km\) above sea level is called as the stratosphere.
Environmental Chemistry

The regions of the atmosphere, where clouds form and where we live, respectively, are
1 Troposphere and Stratosphere
2 Troposphere and Troposphere
3 Stratosphere and Stratosphere
4 Stratosphere and Troposphere
Explanation:
Troposphere is the lowest region of atmosphere bounded by Earth beneath and the stratosphere above where most of the clouds form and where life form exists.
