Questions Related to depletion of ozone layer
Greenhouse effect is due to
-
accumulation of $ { O } _{ 3 } $ and depletion of $ { CO } _{ 2 } $
-
accumulation of both $ { O } _{ 3 } $ and $ { CO } _{ 2 } $
-
accumulation of $ { CO } _{ 2 } $ and depletion of $ { O } _{ 3 } $
-
presence of green plants on the Earth.
Read the given statements and select the correct option.
Statement 1: The average temperature of Earth has increased by $ 0.6 $ during the past century.
Statement 2: There has been a progressive increase in the use of fossil fuels generating more greenhouse gases.
-
Both statements 1 and 2 are correct.
-
Statement 1 is correct but statement 2 is incorrect.
-
Statement 1 is incorrect but statement 2 is correct.
-
Both statements 1 and 2 are incorrect.
The various greenhouse gases are $ { CO } _{ 2 }, { CH } _{ 4 }, { CFC } _{ s } $ and $ { N } _{ 2 }{ O } $. Excessive use of fossil fuel is adding more $ { CO } _{ 2 } $ to atmosphere. This increase in concentration of greenhouse gases has led to considerable heating of earth leading to global warming. During the pas century, the temperature of earth has increased by $ 0.6 $.
Identify the incorrect statement from the following
-
Oxides of nitrogen in the atmosphere can cause the depletion of ozone layer
-
Ozone absorbs the intense ultraviolet radiations of the sun
-
Depletion of ozone layer is because of its chemical reactions with CFC
-
Ozone absorbs infrared radiations
Ozone doesn't absorb infrared radiation , it absorbs ultraviolet radiations .
Which of the following is not a greenhouse gas?
-
Methane $CH _4$
-
Ozone $O _3$
-
Oxygen $O _2$
-
Carbon dioxide $CO _2$
Oxygen is not greenhouse gas, because they are transparent to infrared light.
In absence of Green House Gases, the temperature of Earth shall fall down to ___
-
-18 degree Celcius
-
-15 degree Celcius
-
-20 degree Celcius
-
-10 degree Celcius
Because Green House Gases are responsible to trap heat in earth surface. If green house gases are absent, the temperature of Earth shall fall down to -18 degree Celcius
Correct percentage of two green house gases is
-
$N _2O-6\%, CO _2-86\%$
-
$CH _4-20\%, N _2O-18\%$
-
$CO _2-40\%, CFC-30\%$
-
$CFC-14\%, CH _4-20\%$
Which of the following is a green house gas?
-
Methane
-
CO
-
Water vapour
-
Oxygen
Carbon dioxide is called a green house gas because
-
It emits light
-
It traps infra red radiations
-
It traps ultraviolet radiations
-
It is involved in photosynthesis
Which greenhouse gas contributes 20% to global warming?
-
Methane
-
N$ _2$O
-
CFCs
-
CO$ _2$
Earth is kept warm due to green house flux.
-
True
-
False
