Directions :
The following five (5) items consist of two statements, Statement I and Statement II. Examine these two statements carefully and select the correct answer using the code given below.
Statement I :
34. Global warming signifies the rise in global surface temperature.
Statement II :
The increase of concentration of greenhouse gases in the atmosphere causes the rise in global surface temperature.
[amp_mcq option1=”Both the statements are individually true and Statement II is the correct explanation of Statement I” option2=”Both the statements are individually true but Statement II is not the correct explanation of Statement I” option3=”Statement I is true but Statement II is false” option4=”Statement I is false but Statement II is true” correct=”option1″]
– Statement II: Greenhouse gases (like carbon dioxide, methane, nitrous oxide, etc.) trap heat (infrared radiation) in the Earth’s atmosphere, creating a warming effect. An increase in the concentration of these gases enhances this trapping, leading to a rise in global surface temperature. This increase is primarily attributed to human activities.
