Question
Global warming is caused by ‘greenhouse effect’.
✓
Answer
- Carbon dioxide along with methane, nitrogen oxides and CFCs can absorb infrared radiations reflected from the earth’s surface.
- The blanket formed by these gases in the atmosphere traps the reflected infrared rays and produces heat on the earth’s surface which results in greenhouse effect.
- The greenhouse effect in turn causes global warming.
