Current Question (ID: 17857)

Question:

$\text{Gases responsible for greenhouse effect are:}$ $1.\ \text{Carbon dioxide (CO}_2\text{)}$ $2.\ \text{Ozone (O}_3\text{)}$ $3.\ \text{Nitrous oxide (N}_2\text{O)}$ $4.\ \text{All of the above.}$

Options:

1. $\text{Carbon dioxide (CO}_2\text{)}$
2. $\text{Ozone (O}_3\text{)}$
3. $\text{Nitrous oxide (N}_2\text{O)}$
4. $\text{All of the above.}$

Solution:

$\text{HINT: CO}_2\text{, N}_2\text{O and O}_3\text{ all are greenhouse gases.}$ $\text{Explanation:}$ $\text{A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.}$ $\text{Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, ozone, and some artificial chemicals such as chlorofluorocarbons (CFCs).}$
