Question

Which of the following is not a green-house gas?
A.\[C{O_2}\]
B.\[{N_2}O\]
C.\[{O_3}\]
D.\[{N_2}\]

Answer 1

Hint: About three fourth of the sun’s energy reaching the earth is absorbed by the earth’s surface which leads to an increase in temperature of the surface of the earth. Some of the heat is trapped by gases such as carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbon compounds, and water vapor in the atmosphere. An increase in the concentration of these gases leads to the effect of Global Warming which is a potential threat to today’s world.

Complete step by step answer:
Step 1
Heating of the earth and its environment due to radiation of the Sun trapped by carbon dioxide and other gases in the atmosphere is known as the greenhouse effect. The name greenhouse has been taken from the glass structure called the greenhouse which is used to grow green plants in the colder countries. The glass structure allows the sunlight to reach inside but does not allow the reflected radiation to escape, thus heating the greenhouse.
Step 2
The sunlight received by the earth has three components: the ultraviolet radiation, the visible light, and the infrared radiation. As sunlight passes through the atmosphere most of the U.V. radiation is absorbed by the ozone layer and around \[30\% \]of the IR radiation reaches the earth’s surface and heats it.
Step 3
As the earth’s surface starts heating up, it starts emitting radiations having lesser energy and hence have a longer wavelength. Some parts of the emitted radiations are absorbed by the greenhouse gases resulting in restoring the warmth of the earth’s surface even in the absence of sunlight.
Step 4
The various greenhouse gases are carbon dioxide, methane, chlorofluorocarbon, ozone, nitrous oxide, and water vapor.
Hence the gas which is not a greenhouse gas is nitrogen and the correct answer for the given question is option d).

Hence the gas which is not a greenhouse gas is nitrogen and the correct answer for the given question is option d).

Note:When the concentration of greenhouse gases rises it leads to global warming which can have far-reaching consequences on the earth’s atmosphere. Climate change includes both global warmings driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns.
