Earth 39 s atmosphere is composed primarily of nitrogen and oxygen Consider the following about thes...........

Explanation:

They are transparent to outgoing infrared radiation, which means that they do not absorb or emit solar or infrared radiation. The image below explains the absorption by different gases.
However, there are other gases in Earth's atmosphere that do absorb infrared radiation. These gases are known as greenhouse gases.
Water vapor (H2O) is the strongest greenhouse gas, and the concentration of this gas is largely controlled by the temperature of the atmosphere. As air becomes warmer, it can hold more moisture or water vapor.
