Current Question (ID: 17849)

Question:

$\text{Which, of the following, gases contributes nearly 50 \% to the green house}$ $\text{effect (which, in turn, causes global warming) ?}$

Options:

1. $\text{SO}_2$
2. $\text{SO}_3$
3. $\text{CO}_2$
4. $\text{Water vapour}$

Solution:

$\text{HINT: CO}_2 \text{ is major green house effect gas.}$ $\text{Explanation:}$ $\text{A greenhouse gas is a gas that absorbs and emits radiant energy within the}$ $\text{thermal infrared range, causing the greenhouse effect.}$ $\text{The various gases which bring green house effect responsible for global}$ $\text{warming are the following the relative contributions:}$ $\text{Various gases Relative contribution}$ $\text{Carbon dioxide 50\%}$ $\text{Water vapour 2\%}$ $\text{Nitrous oxide 4\%}$ $\text{Ozone 8\%}$ $\text{Chlorofluorocarbons 17\%}$ $\text{Methane 19\%}$
