Question

The greenhouse effect is due to the presence of
(a) Ozone layer in the atmosphere
(b) Infrared light reaching the earth
(c) Moisture layer in the atmosphere
(d) ${ CO }_{ 2 }$ layer in the atmosphere

Answer 1

It is a natural phenomenon and is beneficial for us. Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life. Human action, however, has increased the presence of these gases in the atmosphere — mainly, ${ CO }_{ 2 }$ and ${ CH }_{ 4 }$.

Complete answer:
The gases which are transparent to solar radiation but retain and partially reflect back long-wave heat radiations are called greenhouse gases. Ozone harming substances are fundamental for keeping the earth warm and neighborly. The various greenhouse gases are carbon dioxide (warming effect $60\%$), methane (warming effect $20\%$), chlorofluorocarbons or CFCs (warming effect $14\%$), and nitrous oxide (warming effect $6\%$). Other gases of minor importance are water vapor and ozone.

Additional information: The greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) brought about by the presence of water vapor,${ CO }_{ 2 }$, ${ CH }_{ 4 }$, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapor has the biggest impact. The origins of the term greenhouse effect are unclear. French mathematician Joseph Fourier is once in a while given credit as the principal individual to coin the term greenhouse effect dependent on his decision in 1824 that Earth's atmosphere.
So the correct answer is ‘${ CO }_{ 2 }$ layer in the atmosphere’.

Note: The atmosphere allows most of the visible light from the Sun to pass through and reach the Earth’s surface. As Earth’s surface is heated by sunlight, it radiates part of this energy back toward space as infrared radiation. This radiation, in contrast to visible light, will in general be absorbed by the greenhouse gases in the environment, increasing its temperature.
