Question

The greenhouse effect is due to the presence of
A.The ozone layer in the atmosphere
B.Infrared light reaching the Earth
C.Moisture layer in the atmosphere
D.\[C{{O}_{2}}\] layer in the atmosphere

Answer 1

Hint:The greenhouse effect is an important phenomenon to sustain life on Earth. The greenhouse effect refers to the trapping of the sun’s heat by greenhouse gases that form an insulating shield around the earth. The greenhouse gases involve methane, chlorofluorocarbons, carbon dioxide, nitrogen oxide, and fluorinated gases.

Complete answer:The Earth’s atmosphere is made up of dense layers of different gases. The greenhouse gases are one of the very important parts of Earth’s atmosphere. The greenhouse gases include carbon dioxide, nitrogen oxides, fluorinated gases, methane, etc. The greenhouse gases have the capability to keep Earth’s surface warm and provide sustainable temperature to all the life forms on Earth. These gases entrap the sun’s radiations of heat and act as a glass shield of the greenhouse that insulates the Earth’s atmosphere. The entrapped heat of the sun is responsible for the warmth we experience. Without greenhouse gases or the greenhouse effect, the Earth’s temperature will go freezing and which will lead to the freezing of life forms on Earth. Carbon dioxide is a major greenhouse gas that accounts for the warming effect of $60%$.
Now, let us discuss other options.
The ozone layer is a gaseous shield of Earth present in the lowers region of the stratosphere layer of Earth. The ozone layer acts as a protective covering for the earth by blocking harmful UV or ultraviolet radiation from the sun.
Infrared light is a portion of sunlight radiation that is emitted by the sun and emitted on Earth’s surface. Infrared light has extensive use in various fields related to science and industry as important electromagnetic radiation.
Moisture refers to the amount of humidity or water vapor levels present in the air.
Hence, the right answer is option D. It is due to \[C{{O}_{2}}\] the layer in the atmosphere that causes the majority of the greenhouse effect.

Note:Global warming is now a common phenomenon that is heard in almost every environment-related activity. It is due to the gradually increasing temperatures on Earth. The greenhouse effect is essential for Earth but it is exceeding its normal values due to increased pollution. The increased pollution is leading to excess releases of greenhouse gases in the atmosphere that leads to the elevated greenhouse effect. It is dangerous for Earth. If the temperature exceeds a maximum tolerance limit, the Earth will burn out or end in disasters.
