Question

Carbon dioxide is the major component of greenhouse gases.
(A) True
(B) False

Answer 1

In the above question, it is given that carbon dioxide is the major component of greenhouse gases. We have to see whether this statement is true or not. Greenhouse gases are the gaseous compounds that are present in the atmosphere which are capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.

Complete step by step solution
We know that greenhouse gases are the ones which contribute towards global warming.
The gases in the atmosphere absorb radiation, and hence, traps and holds the heat leading to the greenhouse effect. The most significant greenhouses gases are water vapour ( ${{\text{H}}_{\text{2}}}{\text{O}}$ ), carbon dioxide ( ${\text{C}}{{\text{O}}_{\text{2}}}$ ), methane ( ${\text{C}}{{\text{H}}_{\text{4}}}$ ) and nitrous oxide. The atmospheric carbon dioxide has increased manifold throughout the year.
There are three factors which determine the degree upto which greenhouse gas can affect global warming. These include the abundance of the gas in the atmosphere, how long it stays in the atmosphere and its global warming potential.
Hence, we can conclude the although ${\text{C}}{{\text{O}}_{\text{2}}}$ is not the primary reason of global warming but it is a major component of greenhouse gases. Hence, the statement, carbon dioxide is the major component of greenhouse gases is true.
So, the correct option is option A.

Note:
Greenhouse gases have devastating effects on both environment and health. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.
Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
